I cannot find any tech info on this unit so am doing some guessing here.

Unplug the unit and at least one wire from the thermal fuse (item K560 in Section 3).
This is the thermal fuse that will kill power to the motor.
Unplug the unit and check the fuse with a meter should be 0 ohms.

Jiggery Pokery method is.
Unplug the unit.
Remove both wires from the fuse, short them together and tape them up so they will not short to the frame.
Plug the unit in and give it a try.

If blown, replace the fuse ASAP as it is a critical safety device re: prevents lint fires which can turn into house fires.

Also clean/check your vent system and the blower as these are the most common causes of it blowing.


In the same section F140 is a hi-limit thermostat. If the temperature in the heater assembly gets too high it will open. Note that it will re-close once the heater cools down. F130 is a thermal cut-off (fuse) (non-resettable). It will blow if the temperature in the heater gets too high and must be replaced. It kills power to the heater so if blown the unit runs but has no heat.

FYI: The thermal fuse is an additional back-up safety device for the hi-limit thermostat. It blows at a higher temperature than the hi-limit. So lets say there is a too hot condition. The hi-limit opens and when the heater cools it closes again so the hi-limit is regulating the heater temperature. The problem is that it's contacts are not made to do this so after a while they fuse together so no temperature regulation. The temperature rises until it blows the thermal cut-off.
