Check filter light keeps blinking. Unit will run but no heat. I have completely disassembled and cleaned everything including duct work, blower motor, inside unit. Still flashing check filter light. Is there a sensor to replace? thermostat? Thx
Answer Hello Paul,
The parts you need to check with a test meter are the centrifugal switch in the motor (AP4438218), the safety thermostats (AP4440977), (AP4440976), the high limit thermostat (AP4440975), and the heating elements' inner and outer coils (AP4439759). These are all of the components in the heating circuit. If all of these components check good, the control (AP4442894) has failed.
Dryer turns on, drum rotates for a few seconds, then stops. Tested on air dry and get same result. There is an electrical burn odor. What can be the cause and how do I test part? Thank you!
This issue sounds like the run winding on the motor may be bad. The unit will start via the start winding and after a few seconds the centrifugal switch switches to the run winding and keeps unit running. The motor windings should have a resistance value of 3-5 ohms. Check from terminals 1 to 3 for resistance values.
Dryer runs but wont heat up, checked and cleaned sensors, gas flow is okay (shutoof is open), vents are okay - air coming out but cold. I reset the house circuit breaker as per manual.
Answer Hello Dennis,
You will want to look for a bad heating element or thermostats/thermal fuses. Check continuity on the themostats, thermal fuses and heater. If any are open then it needs to be replaced.
