I'm working on a Bosch Axis dryer that won't heat. I've changed the heater element (including overtemp thermal) and the control board which drives the heater. Gets warm but not hot. I don't have documentation for the dryer. There are 2 temp sensors in dryer but not sure where they are. There are 2 sliding probes that contact the drum. Are these the sensors? I looked up parts at Appliance Parts Pros, and they list a temp thermostat, but I don't know where this is either. Anyone familiar with this model who can lend a hand?

Thanks,
Paul

Paul,

Did you clean the heat exchanger (condenser)? It should be cleaned 3-4 times a year.

Hi Gene. Thanks for your reply. No, I haven't cleaned the condenser. Would a dirty condenser prevent the heater from coming on? Also, there is a temp regulator, I believe, mounted somewhere near the dryer door. Would a defective one also prevent the heater from coming on? I see that this sensor plugs directly into X11-2 connector on power module.

Regards,
Paul

Paul,

Lets do one thing at a time. Clean the condenser first and post the result.

I also am having trouble with a dryer not heating. After resetting the thermal overload it will work for about a week and then not heat again. The dryer runs, just no heat. Checked continuity of sensors and all read within parameters. Heater elements read within specs and are clean and free of debris. The relays on the control board have dark areas on them where the contacts are but as they all are this way assume it to be normal.
Thanks for any response..
I also noticed that none of the threads for this issue were ever completed. Is there an unresolved issue with this particular unit??
