I think the thermal fuse is shot but when I check it for voltage I show 110v from one side to the other. It's like one side of it ( the wiring) is grounded out. This is the second time in one year that this fuse has gone bad. I have also replaced the control panel. Any ideas?
Answer Warren, Check for voltage at the thermal fuse by checking for 120 VAC from each terminal to chassis ground. This will verify if you have voltage in and out of the fuse. Then check and make sure the wiring connections in the junction box on the front frame, behind the lower kick plate and access panel. Make sure the connections are tight and there is no discoloration or melted areas on the wiring. From there check the wiring at the heater element and thermostat. Make sure you have a constant and proper 120 VAC, polarized power supply. Any loose connections and low voltage issues can cause the thermal fuse to open prematurely.
