DRYERTROUBLESHOOTING
PROBLEM Motor runs but drum does not operate Drum operates but is noisy Motor will not stop Motor does not start Slow drying- improper drying Clothes not drying on auto- dry setting Drum turns but heat does not come on Element burns out frequently
RESISTORS Theresistor,locatedin thethermostatheatercircuit, causes the thermostat heater to generate varying amounts of heat. Resistors are connected to the timer or selector switches. Refer to the applicable wiringdiagram. Resistors are checked with an ohm meter and resistorvalues aremarked on theschematic wiring diagram. A bad resistor will give improper drying temperatures. CONTROL THERMOSTAT Thethermostat and biasheater are locatedon the blowerhousing. CHECKING THE CONTROL THERMOSTAT Remove harness wires from the thermostat. Determinetheinteriorwiringbyreferringtothewiring diagram. Use an ohm meter to check the thermostats. 1. Remove the exhaust venting from the rear of
dryer. Place a thermometer (pocket type readingatleast 300°F.)in rearof exhaust pipe. If dryer is installed between cabinets, making rear access difficult, the temperature can be checked by placing a thermocouple in the lint trap opening. Thermocouple shall be located oneinchtotherightoflintscreenopening center line and extend three inches below the top of opening.
2. Set timer for 30 minutes, or long enough to
permit cycling of thermostat.
3. Allow thermostat to cycle 3 or 4 times. 4. Checktemperature immediately after thethird
orfourthcycle ofthermostat.The temperatures (dependingon thetemperature setting) should conform to those listed in the Temperature Chart. - ATEXHAUSTDUCT - NO LOAD

HI-LIMIT THERMOSTAT The hi-limit thermostat, single-pole, single throw switch wired in series with the control thermostat andheatsource, ismounted to thetop of theheater housing. Should the control thermostat fail or an air blockage occur, raising the heater housing temperature to 260° F. on electric or 240° F. on gas., the hi-limit thermostat opens the circuit to
the heat source and allows the heater housing to cool down to 190° F. To check the thermostat, remove drum. To check forstuck contacts inthe thermostat, startthe dryer and run on HIGH heat with the exhaust duct completelyblocked.Thehi-limit thermostatMUST openwithin three minutes. To check for an open thermostat, remove the harness wires from the thermostat terminals. Test forcontinuity.Youshould havecontinuity througha goodthermostat at room temperature.
SAFETY THERMOSTAT The safety thermostat is wired in series with the motor for ELECTRIC MODELS and the burner for GAS MODELS. The purpose of the safety thermostat is to shut down the dryer if the control thermostatandhi-limit thermostat failtoopen. Once the safety thermostat has opened, it must be replaced.The condition thatcaused itto openmust becorrected. HEATERASSEMBLY(ELECTRIC ONLY)
The heater assembly (208/240 volts) is located behindthedrum.Perforationsinthedrum back allow heated air to be drawn into the drum. Theheater isan opencoil typeheater madefrom a continuouscoilofresistancewireattachedtoa metal support plate with ceramic stand offs. HeaterAssemblyTesting: 1. Disconnect Laundry Center from electrical
supply.
2. Removedrum. 3. Removeleads to the heaterelement. 4. Connect ohmmeter across heater element
terminals.
5. Checkeach terminalto ground. 6. Ifopen or grounded, replace heater element. To Remove or Replace HeatingElement: 1. Disconnect Laundry Center from electrical
supply.
2. Removedrum. 3. Disconnect wires from safety thermostat, hi-
limit thermostat, and ceramic insulator.
4. Removefourscrews securingheating element
assemblyto rear panel andremove assembly.
5. Installnew heating element. 6. Reverseprocedureto reassemble.
IGNITOR The ignitor is a silicon thermistor. When it attains
approximately 1800 F, the sensor (mounted on the side of the burner tube) detectes this high radiant heat and opens its contacts.
This energizes the secondary solenoid valve coil, allowing gas to flow through the gas valve orifice and impinge upon the hot glowing ignitor. The total sequence occurs within 15 to 90 seconds. The igniter is mounted to the burner at an angle with the silicon carbide stem extended into the flame area. The stem is very fragile and susceptible to contamination from skin oils. HANDLE WITH CARE by using the ignitor's insulated support. To test the ignitor: 1. Disconnect Laundry Center from electrical supply. 2. Remove the dryer access panel and safety cover. 3. Disconnect plug connector from ignitor-to-coil harness. 4. Check resistance value of ignitor. It should be
approximately 50 to 800 Ohms depending on the
room temperature. To replace ignitor: 1. Disconnect Laundry Center from electrical supply. 2. Remove burner assembly. 3. Remove burner tube from burner assembly. 4. Remove the 1/4" hex head screw and washer
securing ignitor to its mounting bracket.
5. Reverse procedure to reinstall.
DOOR SWITCH Whenever the door is opened, the door switch will open the circuit to the motor and the external switch in the motor will open the circuit to the heat source. CHECKING THE MOTOR The drive motor is 1/4 H.P., 1725 RPM with automatic reset overload protector. 1. Disconnect electrical current and remove
ventilation panel. Remove harness wires from motor.
2. Operate motor by connecting a properly fused
service cord to terminals 4 and 5. The motor should start and run.
3. If motor runs, problem is open circuits in the dryer
electrical or control system. If motor does not run, check the centrifugal switch.
4. When motor runs and the problem is NO HEAT,
check continuity between terminals 1 and 2 with the switch button out (run position).
No continuity shows the switch is inoperative.
Replace motor.
DRYER DRIVE BELT To Remove or Replace Dryer Drive Belt: 1. Disconnect Laundry Center from electrical supply. 2. Remove front panel and air duct assembly. 3. Disconnect belt from idler pulley and motor pulley. 4. Remove belt from dryer drum. 5. Install new belt. 6. Reverse procedure to reassemble.

CAUTION
THIS MACHINE MUST BE
ELECTRICALLY GROUNDED
It can be grounded thru the ground lead in the 4-prong power cord, if plugged into a properly grounded appliance outlet or thru a separate No. 12 or larger wire from the cabinet to an established ground. In all cases, the grounding method must comply with any local electrical code requirements.
IMPORTANT - RECONNECT ALL
GROUNDING DEVICES
ALL PARTS OF THIS APPLIANCE CAPABLE OF CONDUCTING ELECTRICAL CURRENT ARE GROUNDED. IF GROUNDING WIRES, SCREWS, STRAPS, NUTS OR WASHERS USED TO COMPLETEA PATH TO GROUND AREREMOVED FORSERVICE, THEY MUST BE RETURNED TO THEIR ORIGINAL POSITIONANDPROPERLYFASTENED.
OPERATION - DRYER Onelectricmodeldryers, airisdrawn into theheater housing and across the open coils of the electric heater. On gas model dryers, air is drawn into the combustionchamber andover the burner flame. It thenis drawnthrough thetumbling clothes,picking up moisture and lint. Lint is filtered out as the air passes from the drum into the blower where it is discharged out the vent. The air temperature is controlled by the biased thermostat according to thesetting of thefabric selector switch.The length of the drying cycle is controlled by the number of minutes selected on the timer, or automatically controlled by the timer, in conjunction with the electronic moisture sensor, for the type of fabric selected (automatic dry cycle). To operate thedryer,firstcheck the lint screen and be certain that the screen is completely free of all lint. Place clothes in dryer and close door. (Dryer will not operate unless door is closed.) 1. Select the drying time, or automatic drying
cycle, by turning timer knob to the right.
2. Setdryingtemperature using timer for the type
offabric beingdried.
3. To start the dryer, turn the start knob to the
right and hold for 2 seconds.
DRUM SPEED 48-54 RPM in a counterclockwise direction as viewedfrom the front.
