Hi and welcome to
FixYa, I am Kelly.
For post reference use this parts diagram:

Usually either the capacitor (Item 20 above) or the diode (item 19 above) causes this problem.
You POWER OFF the unit completely. CB OFF or local plug un-plugged.
- Open the chassis and you FIRST discharge the capacitor by holding a screwdriver way back on the handle and GROUND the capacitor across the 2 terminals at least 3 times. (
Trust me if the capacitor is good and you do not do this your in for a really bad day)
- Disconnect one end of the power diode and then test the diode for continuity 2 times reversing the leads. It should read continuity on ONE direction / polarity only. If it reads open in both directions or short in both directions it has failed.
- Next test the capacitor by probing the terminals and again reversing the leads. On a scale of R x 1,000 or R x 10,000 (X 10 better) your looking for a momentary jump in resistance and then the meter returns to near infinity. (Just make sure all the leads are off ONE set of terminals first) Reverse the test leads and probe again. You should see the resistance jump and then fade to near infinity EACH time the leads are reversed..
These are the 2 most common reasons for the unit to run but not heat. If after testing you still have no isiolated the problem, respond with your results and we can proceed from there.
