Will not start or run:

 

-

  All wires are hooked up to their corresponding 

terminals. 

-

 Dryer 

is 

plugged 

in. 

-

  Blown fuse or circuit breaker. 

-

 Start/Pause 

switch 

functional. 

-

 Control 

Board 

operational. 

-

  Drive motor functional. 

-

 Blown 

thermal 

fuse. 

Motor runs/ tumbler will not turn:

 

-

  Belt off or broken/damaged. 

-

  Idler tension spring too weak or stretched. 

-

  Idler pulley jammed or stuck. 

Runs a few minutes and then stops:

 

-

  Lint buildup around drive motor. 

-

 Low 

voltage 

present. 

-

  Blower impeller blocked in blower  

 housing. 

-

  Drive motor - start switch contacts stuck closed. 

Blows fuses or trips circuit breaker:

 

-

  The amperage readings are at 240 volts. One line 

will be 24 amps and the other line will be 21 amps. 
The neutral line will be at 3 amps. If the above 
amperages are present, then the house wiring, fuse 
box or circuit breaker should be suspect. 

-

  Shorted heating element to housing. 

-

  Incorrect wiring or a wire shorting to ground. 

-

  Drive motor winding shorting to ground. 

Will Not Dry 
Will not heat (motor runs):

 

-

 Open 

heating 

element. 

-

  Hi-Limit trips easily or is open. 

-

  Regulating thermostat trips easily or is open. 

-

  Membrane switch open. 

-

  Drive motor centrifugal start switch not allowing 

voltage to  heating element. 

Improper drying/clothes wrinkled/ rough 
texture/long dry time: 

-

  Lint filter is not clean. 

-

  Restriction in exhaust. 

-

  Outside exhaust hood damper door stuck closed. 

-

  Exhaust too long, too many elbows, flex ductwork 

installed. 

-

  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. 

-

  Clothes too wet due to insufficient spin out by 

washer. 

Will Not Shut Off 

 Short 

in 

Sensor 

Circuit. 

 

Check Membrane Pad. 

 

Check Electronic Control Board. 

Troubleshooting the electronic  
control circuit: 

-

  Check for miswiring of the electrical connector at the 

electronic control board. 

-

  Does not shut off, then the problem is in the 

electronic control unit. Disconnect the sensor wire 
from the sensor bar. If the dryer runs for about 20 
minutes, then shuts down or the timer advances, 
then the electronic control unit is good and the 
problem lies in the sensor bar.  

-

  Check sensor for continuity. If found, replace sensor 

bar or clean with alcohol. Some fabric softener 
sheets will coat the sensor bars. 

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 bearings. 

-

 

Roaring

 

Check for blower wheel rubbing on blower 

housing or bad motor bearings. 

-

 

Popping or squealing sound

.

  Check for a sticky or 

frayed belt. 

Display shows 18 or other unexpected display

:- 

-

  If a consumer inadvertently presses the hidden 

switch when a cycle 

is not running

, there will be an 

audible beep and the display will change to 18.  The
