Whirlpool electric dryer will not heat

Check the thermal limit on the side of the heater housing and the blower thermal on the blower housing
the emement limit is at the top of the blower housing and will have 2 red wires going to it
the blower limit will have blue wires going to it
withe the power cord unpluged, remove the wires to these two limits and with a meter on rx 1 ect. read across each of these if you do not get a meter fluctuation , all the way to the right as you check the part os bad

Hello. Heating element's probably O.K. In addition to the breaker, there's probably a THERMAL fuse inside the unit. This will go if it get's too hot.

SOME thermal fuses reset themselves, and some don't. It's a safety issue. You'll probably need to "get inside the dryer" (not the drum - but the overall machine) to find it and check it for continuity (with an ohmmeter). There's probably a schematic inside the dryer that'll help you locate it.

I hope this helps.
