My dryer was running fine, but was not producing any heat so I checked vents (clear of obstruction) and checked the voltage at the outlet (240V). Then I checked all of the fuses and thermostats with a multimeter. The upper high-limit thermostat (aka cut-off thermostat) appeared to be the culprit. I removed it and replaced it with a working one (different part number, but similar temp limits) just to test it before I bought a new one. The dryer would not start. I then re-installed the old thermostat and still the dryer will not start. All wires to thermostats and fuses have been securely re-attached. What could have gone wrong!? Now I don't want to spend $30 on a kit to replace high-limit thermostats because I can't even get dryer to start... Help!

What is the model number of the dryer? In general, the heat circuit including all thermostats, has no effect on the motor circuit. There may be, depending on model, a thermal fuse, generally located on the blower housing, that would affect the motor circuit.

I will get you the model number tonight when I get home but I did check the thermal fuse for continuity and it appeared to be fine. I will confirm this tonight and let you know.
Let me know if you think of anything else.

Thanks!!

Eric,

So, I tested the thermal fuse and it had gone bad (maybe because I tried to run the dryer with the wrong cut-off thermostat?). In any event, I had a spare thermal fuse (same part #) So I put that on and it is running again. So now I've ordered a cut-off thermostat kit that I'm going to install. Stay tuned because I may have more problems after I get it installed...

Thanks for the help.
