General Information
HOW IT WORKS
The cycles are made up of three basic operations.
White & Colors, Permanent Press and Delicates and
Knits. These operation are sequenced by the controls
(timer or microprocessor board) to provide a drying cycle
for each of several different fabrics.
imit
rmostat
Secondary
Coil
Radiant
Sensor
Incoming air is pulled over and around the exterior of the
rotating tumbler. The air passing over the tumbler is
preheated from the warm tumbler. This incoming air also
passes over the inside of the cabinet lowering the
cabinets temperature and minimizing the heat being
dispelled into the laundry area.
Igniter
Gas Valve
Holding &
Booster Coil
The pre-conditioned air is pulled through the heat
enclosure. As the air passes over the flame or heating
element, it is heated causing the air to expand which
increases its ability to absorb more moisture.
Igniter - When the controls call for heat, line voltage is
applied to the igniter. This causes the igniter to heat up
and glow. It can reach a temperature of approximately
2200º F in approximately 30 seconds. Gas contacting
the igniter at this temperature will ignite immediately.
The heated air is pulled up the stack and through the grid
in the tumbler back, through the tumbler, and to the lower
area of the tumbler front. The tumbler is rotating in a
clockwise direction lifting the
garments to the top of the tumbler. The garments fall
free of the clothes lifters through the air stream. As this
tumbling takes place, the garments keep turning over
within the tumbler. Moisture is evaporated from the
garments tumbling in the warm, dry air.
Radiant Sensor - The radiant sensor operates much
like a regular thermostat. It is mounted to the side of
the combustion cone over an opening which exposes
the sensor to the heat of the igniter and burner flame.
In its normal condition, the contacts in the radiant sensor
are closed and the circuit is completed to the igniter.
The igniter glow causes the radiant sensor contacts to
open, thus breaking the circuit to the igniter.
After passing through the garments, the air will contain
moisture and lint. This air is pulled from the tumbler
through a fine mesh filter located in the bottom of the
door opening. The quantity of lint collected on the filter is
dependent upon the size and type of load being dried.
Gas Valve - The gas valve is actually two gas valves,
one in series with the other. The first valve is opened by
a solenoid which has two separate coils built into one
solenoid. This solenoid uses what is termed a split coil.
The coils are referred to as the Holding Coil and the
Booster Coil.
From the filter, the air is pulled into the exhaust blower
and forced out the exhaust system. The high speed
blower is capable of moving up to 220 CFM of air. The
volume of the tumbling chamber is approximately 6.0
cubic feet.
Both coils are needed to lift the armature and open the
valve. The holding coil is strong enough to keep the
valve open once the armature has been lifted.
GAS VALVE ASSEMBLY
The second of the two valves is operated by a one-coil
solenoid. This is called a Secondary Coil.
The gas controls utilize a hot surface ignition system.
The three major components of the gas ignition system
are: Igniter, Radiant Sensor and Gas Valve.

General Information
Holding Coil
Booster
Step 1: Operation: Dryer Controls calling for heat:
The red wire in the gas valve harness is normally the
"hot" side of the line. Voltage is routed to the gas valve
assembly through the cycling thermostat located on the
blower cover and the hi-limit thermostat on the heater
cone. The black wire to the gas valve is normally the
neutral side of the line and is completed through the
motor centrifugal switch.
Secondary
Co
Radiant Sensor Contact Closed
Function of Gas Valve System
The holding coil, booster coil and igniter all receive line
voltage. The holding coil and booster coil open Valve 1.
Valve 2 is still closed, prohibiting gas flow to the burner.
The igniter, operating at line voltage, begins to get very
hot. (As the igniter gets hotter, the resistance of the
igniter drops.) The igniter glow radiates heat to the
radiant sensor.
The sensor, igniter and gas valve are interrelated and
function as ignition and heat source. At the start of the
cycle, the radiant sensor contacts are closed, the igniter
is at room temperature and the gas valve is closed,
blocking the flow of gas. NOTE: On the wiring diagram,
the radiant sensor contacts are wired in parallel with the
secondary coil. This bypasses current around the
secondary coil when the radiant sensor contacts are
closed. Valve 2 cannot open with the radiant sensor
contacts closed.
Holding
Coil
Radiant
Sensor
To
Motor

Coil
Igniter
Valve 1
Valve 2
The secondary coil on Valve 2 is bypassed because the
radiant sensor contacts are closed. By not allowing
voltage to the secondary coil, the second valve cannot
open and prevents gas flow to burner.
The booster coil and the igniter are wired in parallel.
Note: While these two components are in parallel with
each other, they are wired in series with both the
radiant sensor and secondary coil combination.
Step 2: Radiant Sensor Contact Open:
The igniter is now hot and valve one (1) is open. The
heat from the igniter causes the radiant sensor switch
contacts to open.
When the radiant sensor contacts are closed, full line
voltage is available to the booster coil and to the igniter.
With the radiant sensor contacts open, the secondary
coil is no longer bypassed. The secondary coil is now in
series with the parallel circuit combination of the booster
coil and the igniter.
When the radiant sensor contacts open, current has to
flow through the secondary coil on Valve 2 in order to get
to the booster coil and igniter. A significant voltage drop
develops across the secondary coil. While the parallel
booster coil and igniter are still in the circuit, they
become ineffective due to their low resistance and the
resulting reduced voltage available to them.

General Information
Safety Features
Holding
Coil
The design of the system provides for fail-safe operation
in the event of power interruption, ignition failure, or
flame failure as described below.
Radiant
Sensor
Power Interruptions
To
Motor
If the power to the burner assembly is cut off, either by
opening the dryer door or by a power line failure, both
valves in the gas valve assembly will close. Gas flow will
cease.
Booster
Coil
Igniter
Valve 1
Valve 2
Because of the relatively low resistance of the hot igniter,
most of the line voltage is dropped across the secondary
coil. The remaining voltage is dropped across the
booster coil and igniter.
When power is restored to the valve, the radiant sensor
will start the process again. However, if the radiant
sensor has not cooled and the contacts are still open, the
secondary coil will receive full voltage and OPEN with no
gas flowing through the secondary valve.
Since the secondary coil is in series with the booster coil,
the reduced current flow through the booster coil is
insufficient to create a strong enough magnetic field to
help open the first coil valve. When the radiant sensor
cools and closes its contacts, the sensor will shut the
secondary coil again, providing a full current flow to the
igniter and the booster coil, and system will go through a
normal ignition sequence.
Ignition Failures
The secondary coil now opens the second valve
releasing gas across the still extremely hot igniter. The
gas ignites immediately and the burner flame is
established.
When the radiant sensor reacts to the heat from the
igniter and the contacts open, the secondary coil
energizes, opening the secondary valve. This allows gas
to flow to the burner.
If no gas is present or the gas flow is not ignited, the
radiant sensor will cool and the contacts will close,
causing the secondary valve to close, thus allowing the
igniter to reheat. The system will continue to cycle in this
manner until normal ignition occurs or the dryer is turned
OFF.
Note: Since the igniter will cool, the tip is positioned in
the burner flame which keeps it hot and
resistance low.
The ignition cycle is now completed and the drying cycle
begins.
Flame Failure
If the burner flame should go out for any reason, the
radiant sensor contacts will close in about 45 seconds
and the gas system will go through a normal ignition
sequence.
Gas Conversions
The gas valve is set for use with natural gas when
shipped from the factory. Because of differences in
operating pressure and heat content of gases, the valve
must be converted to use fuels other that natural gas.
Conversion kits are available to convert from natural to
L.P. and back to natural. Check parts catalog for correct
part number.

Continuity tests of switches will show virtually no

low value indicate burned or dirty contacts in a switch.
!
CAUTION
Resistance or continuity testing is done with the product
disconnected from power. Failure to do so can result in
damage to your meter.
When checking components or circuit paths for
continuity, external wiring should be disconnected to
eliminate false readings through external paths. Isolate
what you want to test.
For the most part, we will only be concerned with
continuity. Is there a path or not? References are made
between a “closed” (Continuity) reading and an “open (No
continuity) reading. One note, when you get and “open”
reading, try a higher resistance range (setting). A very
high resistance appears as an “open” on the lower ranges.
For best accuracy always “rezero” meter when changing
ranges and/or the physical position of the meter.
Drive Motor Check
The motor features a leadless motor connection,
comprised of a quick connector wire harness which
connects directly to the motor. The connector has two
locking tabs securing the connector to the motor switch.
Press on both locking tabs to release the connector from
the motor switch.
Continuity testing, as related to an electrical component,
is the check of a part for an “open” or closed” circuit.
Press Here to Release
Connector

Electrical components fall into two general categories.
1. Loads - Devices that use or consume electricity.
Examples would include drive motor, timer and
solenoids coils.
With the wire harness connector removed, press inward
on the brown actuator disc in the motor. The start and run
winding can now be checked for proper ohms. Place the
leads from an ohm meter on the proper terminals as listed
in the following chart.
2. Switches - Devices that control the supply of
electricity to the load or loads in a circuit.
Examples include lid switches, timer contacts
selector switch and relay contacts.
Using an ohm meter, you can also check the wiring
harness for continuity from the timer to the motor.

Troubleshooting Procedures
! WARNING
To avoid risk of electrical shock, personal injury or death, disconnect power to unit before servicing, unless testing
requires power.
Centrifugal Switch
Checking heater/gas valve and motor:
1. Disconnect the wire harness from the motor.
2. Place ohm meter leads to terminals 1 and 2.
3. With your thumbs, depress the BROWN disc
located behind the motor switch on the motor
shaft. The BROWN disc actuates the lever of
the motor switch when the motor is at rest. At
optimum motor speed, the disc moves away from
the switch lever. When the disc is pressed in
toward the windings, the actuator arm of the
centrifugal switch will be relaxed. This allows the
contacts to close, completing the heater circuit.
If no continuity is found when the disc is
depressed, change the centrifugal switch.

Motor Test Cord
A motor test cord may be used to electrically check
operation of the various electrical components without
removing them from the unit. Testing in this manner
determines whether or not the part will function
independently of other electrical components. In order to
make an accurate test, proper connection of the motor
test cord is important.
Air Shutter Adjustment
The air shutter has been
stamped "LP" and "N" (for
Natural). Loosen the screw
holding the shutter, rotate the
shutter until the end of the slot
(labeled for the gas to be used)
contacts the screw. Tighten the
screw to lock the shutter in

Aflexible rubber hose is connected to the lower, open end
of the manometer and to the gas source. Gas pressure is
exerted on one of the water columns, pushing it down.
The water level then rises in the other column. The
difference in water levels equals the measure of gas
pressure.
Note: IF HIGH WATER COLUMN PRESSURE IS
DETECTED; the gas flame can damage the
flame spreader on the burner. (this can be
cuased by the wrong orfice, improper air mixture
or high gas pressure. If pressure is as high as
suspected, contact the local gas utilities
company to check the outside regulator.)

Mechanical Troubleshooting
Will Not Shut-Off
On time dry settings, check the following:
Will Not Run
If dryer will not start or run, check the following:
• All wires are hooked up to their corresponding
terminals.
• Timer motor receiving proper voltage.
• Check timer motor connections.
• Timer functional.
Will Not Dry
• Dryer is plugged in.
If dryer will not heat (motor runs), check the following:
• Restricted exhaust caused by plastic or thin
foil flexible duct.
• Blown fuse or circuit breaker.
• Door switch functional...door closed.
• Push-to-start switch functional.
• Timer functional...set in a cycle.
• Drive motor functional.
• Open heating element.
• Hi-Limit thermostat trips too soon or is open.
• Cycling thermostat trips too soon or is open.
• Temperature selector switch mis-wired or contacts
open.
• Blown thermal fuse.
If drive motor runs, but the tumbler will not turn, check the
following:
• Belt off or broken/damaged.
• Idler tension spring too weak or stretched.
• Idler pulley jammed or stuck.
• Timer functional.
• Cycle selector switch mis-wired or contacts open.
• Drive motor centrifugal start switch not allowing
voltage to gas valve or heating element.
If improper drying/clothes wrinkled/rough texture/taking
too long to dry, check the following:
• Restricted exhaust caused by plastic or thin foil
flexible duct.
If dryer runs a few minutes and then stops - motor
overload protector opens, check the following:
• Lint buildup around drive motor.
• Low voltage present.
• Lint filter is not clean.
• Restriction in exhaust.
• Blower impeller blocked in blower housing.
• Drive motor - start switch contacts stuck closed.
• Outside exhaust hood damper door stuck closed.
• Exhaust too long, too many elbows, flex ductwork
installed.
If dryer blows fuses or trips circuit breaker, check the
following:
• Poor makeup air available for the dryer.
• Incorrect tumbler speed. Tumbler belt slipping.
• Blower impeller bound; check for foreign material
in blower area.
• Customer overloading dryer.
• Check clothing labels for fabric content and cycle
selected.
• Gas valve coil opens - weak point in coil opens
when stressed under heated conditions.
• Clothes too wet due to insufficient spin- out by
washer.
Electric Models
• The amperage readings are at 240 volts. One line
will be 24 amps and other line will be 21 amps.
The neutral line will be at 4 amps. If the above
amperages are present, then the house wiring,
fuse box or circuit breaker should be suspected.
• Shorted heating element to housing.
• Incorrect wiring or a wire shorting to ground.
• Drive motor winding shorting to ground.
Gas Models
• During ignition, the dryer will draw 7 amps. With
the burner ON, the dryer will draw 4.5 amps. If
the dryer is drawing amperages below this, then
the house wiring, fuse box or circuit breaker are
suspected to be at fault.
• Igniter harness loose and shorted to base.
• Incorrect wiring or wire shorted to ground.
• Drive motor winding shorting to ground.
Noisy and/Or Vibration
• Thumping. Check for loose tumbler baffle, rear
tumbler roller(s) worn or misaligned, out-of-round
tumbler or high weld seam on tumbler.
• Ticking. Check for loose wire harness or object
caught in blower wheel area.
• Scraping. Check for front or rear bulkhead
felt seal out of position or worn tumbler front
Rulon™ bearings.
• Popping or squealing sound. Check for a sticky or
frayed belt.

PROGRAMMING PROCEDURES
NOTE: Before proceeding please note that an
owner can choose to uncrate a new commercial
machine, hook it up, plug it in and have a unit
which operates.
How to Use the Keypads to Program
the Controls
1. The Whites & Colors keypad is used to
change information in the programming codes,
permitting adjustment. Pressing the keypad will
change the characters by one (1). Rapid
adjusting is possible by holding the keypad
down.
PD units are pre-set at the factory for fixed cycle
price with top off.
PR and PN units are pre-set for free cycle operation
so they can be run without readers or coins.
2. The Permanent Press keypad will advance you
through the programmed codes. Holding the
keypad down will automatically advance through
programs at a rate of one (1) per second.
The appliance is programmed at the factory as
follows:
5 minutes dry time/quarter (Coin 1).
3. The Delicates keypad is used to select or
deselect options. This is an "OFF" or "ON"
selection.
$1.50 dry price (Fixed cycle with top off-PD/
PS models).
$0.00 dry price (Fixed cycle-PR/PN
models).
START OPERATING SET-UP
GENERALUSER INFORMATION
PD and PS Models (Single Load Dryer): Insert
access door key, turn, and lift to remove access
door.
Blank Display: This condition indicates that the
appliance is inoperative.
PD Models (Stacked Dryers): Insert access panel
key and turn.
"0" Minutes Showing in Display: This condition
indicates that the appliance cannot be operated.
Coins dropped during this condition will be stored in
escrow, but cannot be used until normal operation
is restored by opening and closing the door. If the
door switch fails, recovery from this condition is
impossible without service.
PN Models: Insert service key and turn to
"PROGRAM."
PR Models: Once the debit card reader is installed
(according to the reader manufacturer's
instructions), the set-up mode can be entered by
inserting a manual set-up card (supplied by the
reader manufacturer) into the card slot.
Warm Start - After Power Failure: After a delay of
a few seconds, the appliance is restored to the
state that existed at the time of power failure.
"Reselect Cycle" will flash in the display. Select
fabric setting to restart dryer.
If manual set-up card is not available, manual set-
up mode can be entered by removing connector
AA1 on the circuit board.
Pricing
CAUTION: The console must not be opened
unless power is first removed from the dryer.
To access connector AA1, remove power, open
console, disconnect plug on AA1, close console,
apply power to dryer. The dryer is now in the set-up
mode.
After the door is opened, following the completion of
a cycle, the display indicates the cycle price (unless
set for free operation). As coins or debit inputs
arrive, the display will change to lead the user
through the intiation of a cycle.
There are four (4) types of pricing.

Fixed "Vend" Pricing
A dryer set up for "Fixed Cycle" operation can only
accept additional time accumulated by increments
equal to the length of a complete dry cycle. A
maximum of 99 minutes may be purchased; no
additional credit is given when 99 minutes is in the
display.
Accumulator Pricing
If the price is equal to the value of coin 1, then
accumulator mode is in effect (stacked models also
require Fixed Cycle with Top Off option to be
selected). Cycle time can be purchased one coin
at a time (PD and PS models) up to the maximum
time of 99 minutes. While in accumulator pricing,
stacked machines will credit all money to a cycle
with a single button press.
Fixed Cycle With Top Off Pricing
A dryer set to offer "Top Off" capability will allow
time to be added to an existing dry cycle in
increments equal to the number of minutes of dry
time per quarter (coin 1), up to 99 minutes,
regardless of the cost required to start the machine.
No credit is given for coins or debit inputs entered
when the control is displaying 99 minutes.
PR Models: In Enhanced Debit Mode, the Top Off
price can be set independently. (See VALUE OF
COIN 2), and the top off time is calculated
according to the following equation:
top off price
full cycle price
=
=
top off time
full cycle length
Penny increment offset is not applied to top off
purchases.
Free Cycles and PN Models
This is established by setting the cycle price to
zero. When this happens, "select cycle" will appear
rather than a cycle price. Any cycle started as a
free cycle will automatically terminate when the
door is opened.
Debit-Card Ready
This appliance is debit-card "cable ready." It will
accept a variety of debit card systems, but does
NOT come with a debit-card reader. Connection to
the control board is by means of a Molex brand
connector (housing and terminals.) See your
distributor for appropriate connector part numbers.

Stacked Models Only:
This mode is entered by depressing DELICATES for one
second while in any of the set-up codes one through six
(or while dAS displays if operating with Maytag Data
Acquisition setup) or with a diagnostic code present.
Diagnostic codes are cleared on entry and all display

display flashing, the cycle is started by pressing the
UPPER DRYER PERMANENT PRESS key pad. The
cycle consists of seven minutes of heat and one
minute of cool down. The UPPER DRYER WHITES &

the LOWER DRYER DELICATES key pad will cancel
this cycle and exit the diagnostic mode.
2. Lower Dryer Field Diagnostic Cycle – With entire
display flashing, the cycle is started by pressing the
LOWER DRYER PERMANENT PRESS key pad. The
cycle consists of seven minutes of heat and one
minute of cool down. The LOWER DRYER WHITES &
COLORS key pad will increment the diagnostic cycle
minutes up to 99, then roll over to 2 minutes. Pressing
the LOWER DRYER DELICATES key pad will cancel
this cycle and exit the diagnostic mode.
All Single Load Models:

by depressing the PERMANENT PRESS key pad. The
cycle consists of seven minutes of heat and 1 minute of
