What would make the dryer get too hot, even on the lowest setting?
Answer Hello Al,
Several things can cause this. You could have a stuck thermostat, a shorted harness, a heating element that is touching the rear of the drum from worn bearings and glides. The timer contacts could be sticking. This is the kind of problem that you will have to disassemble and search for with a test meter and looking for discolorations.
This unit is old enough that there are no service manuals available on it anymore. I can refer you to the wiring diagram on the unit, if it is still there. It should be either under the main top, in a brown envelope inside the cabinet, in the control panel, or stuck to the back.
My white westinghouse turns on but does not heat up. I checked the heating element it looks ok, I think it maybe a thermostat. How do I test these so that I buy the right part ? The one with part number AP2142632 and has two yellow wires coming from the one side looked to be a little melted. The coating just above the quick connect was a little crispy every thing else seems to be ok. HELP me please
Answer Hi Larry. You need the digital volt/ohm meter part # MA-12815. When you use the R x1 scale in ohms, and touch the meter leads together, the meter will read close to 0-ohms or .01 ohms. Anyway it will not read open or infinity. This is a short test to make sure the meter and battery works in the meter. Then the hi-limit switch will be normally closed before the heater will work. The thermal fuse , hi-limit fuses will all read closed. If they are open then that plus finding out why it opened will be the issue. Such as a normally clogged vent system will "overheat" the element to a white hot and expand the coils of the element. They in turn will sag and touch ground, shorting out and burning open after many uses of expanding and contracting. The element will normally read between 8-18 ohms of resistance. Then check each terminal to ground to quickly find a short to ground. Heater assy. part # 3937010. Thermal fuse part # 134120900. On the side of the exhaust tube is the control thermostat which needs to read closed also. part # 3204307. Thank You.
