Trouble Shooting Fault Codes
F1 Shorted sensor or shorted sensor wire harness
F2 Open sensor or sensor wire harness disconnected
F3 EEPROM corrupted. Dryer will not start and “F3” appears on the 4-digit display. The power to
the dryer must be cycled to reset the controller. Fault should only occur when starting a dry
cycle.
F4 Gas valve on fault. The drying temperature did not increase 1ºF. in 15 minutes. “F4” will ash
on the display and the dry cycle will nish without calling for heat (energizing gas valve).
Opening the door or pressing the STOP key will reset the fault and clear the remaining time in
the dry cycle.
F5 Temperature fault. The drying temperature is at least 25ºF. above the temperature setting.
“F5” will ash on the 4-digit display and the dry cycle will nish without calling for heat
(energizing the gas valve). The power to the dryer must be cycled to reset the controller.
Troubleshooting Tips
Symptom Probable Cause Suggested Remedy
Tumbler does not turn Drive belts Check both drive belts.
Replace if failed.
Drive motor Check capacitor and
motor. Replace if failed
Door switch Check door switch
contacts and
adjustment. Adjust or
replace the door switch
Electronic Control Is electronic control
closing motor relay to
power drive motor?
Check for motor light on
electronic control. If no
light change control. If
light is on, check voltage
and wiring to motor.
Symptom
Probable
Cause
Suggested Remedy
Tumbler turns
but no spark
at burner
Glass fuse Check small glass control fuse in back of dryer.
Replace if failed.
Temperature
Sensor
The temperature sensor should have between
30,000 ohms and 60,000 ohms resistance at
room temperature if okay. Replace if not in this
range.
Ignition Check for 24VAC output from transformer.
Transformer Replace if have 120V between black & white
and no 24V between red and yellow.
Over
temperature
Check to see if manually resettable thermostat.
Thermostat is kicked out. Reset by pushing red
reset button.
Ignition control Check for 24VAC coming into the control on the
at burner red wire. If voltage, then check for
24VAC out on the brown wire. Also check for
spark at the ignitor. If no 24VAC output or no
spark to the ignitor, replace ignition control.
Air Flow Switch Check air ow switch to be sure it closes when
dryer is running. If not, adjust or replace
switch.
Hi-limit Check for continuity. Should be 0 ohms
resistance when cold. If not, replace
thermostat.
Gas supply No gas can cause system lockout
Electronic
Control
Is electronic control closing gas relay to power
Control heat circuit? Check for gas light on
electronic control. If no light change control. If
light is on, check voltage and components in
heat circuit at transformer at rear of unit.
