Nutone model 9422P-R01bulb heater. I have this bulb heater connected to a thermostat type switch. When I turn the switch to lets say 10 minutes it only turns on for 20/30 seconds then turns off. It will come back on again but only for a brief time IE 20/30 seconds.I'm thinking the switch is the problem? If so what type Model should I have installed?? Thanks

pull out flame sensor and sand. Re install and call for heat

You should probably replace the heater motor. All the parts should still be available for you fan and it should only take a few minutes to change out.

My guess it will be the motor.That would be the first thing I would do is replace it.

Sounds like the relay that controls the heating element is sticking.

The "diode" that your electrician mentioned is actually a one shot thermal fuse.
You can either go to the Nutone website for parts, or remove the thermal fuse, extract the info written on it and buy a replacement. Mine was a 100C 10A thermal fuse. I got mine from DigiKey.
