Will Not Run 
Will not start or run:

 

•  All wires are hooked up to their corresponding 

terminals. 

•  Dryer is plugged in. 
•  Blown fuse or circuit breaker. 
•  Door switch functional...door closed. Check for 

error code 3 (See Table for code definition). 

•  Start/Pause rotary selector dial functional. 
•  Control Board operational. 
•  Drive motor functional. 
•  Check motor winding resistance: 2.88ohms 

between pin #3 and 4, 3.5ohms between pin #4 
and 5. 

 

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. 

Gas Models 

•  During ignition the dryer will draw X amps. With the 

burner ON, the dryer will draw X amps. If the dryer 
is drawing amperages above this, then the house 
wiring, fuse box or circuit breaker is 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. 

 

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. 
• Check 

Thermistor. 

 

Will Not Dry Gas Models 
Poor Gas Ignition 

When the dryer is operated on a heat setting, the 
igniter should be energized and burner shall fire within 
45 seconds at 120 VAC. The failure of a component in 
this system will usually be indicated by one of three 
symptoms: 
 

The igniter does not glow. 

If the igniter does not 

heat up, remove power and using an ohmmeter, 
check the following: 
•  Open flame sensor 
• Open 

igniter 

•  Shorted booster coil 
• Open 

wiring 

•  Bad motor switch ( Neutral supply) 
•  No power from control ( L1 supply) 

Igniter glows - No gas ignition. 

If the igniter heats 

up but the main burner flame is not ignited, remove 
power and using an ohmmeter, check the following: 
•  Open secondary coil 
•  Open holding coil 
•  Open wire harness 
•  Stuck flame sensor (Stuck closed) 

The gas is ignited but the flame goes out. 

If a 

normal ignition takes place and after a short while the 
flame goes out, check for the following: 
•  Radiant sensor contacts opening  
 prematurely. 
•  Weak gas valve coil may open when 

stressed by higher temperatures. 

• Weak 

Hi-Limit 

• Poor 

venting 

•  Bad drum seals

 

 
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 intake 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.
