How would you know high limit thermostat is defective. need to know before ordering part
Hi, you'll need a ohm tester (multi-tester) you will have to remove / disconnect wires from hi-limit, in normal room temperature, place tester lead on terminals where you remove wires, if you get a beep/continuity, hi-limit is o/k, if no beep/continuity, hi-limit faulty, for further test you can heat up hi-limit, (oven) and check with tester, hi-limit switch off when temperature gets to high, and switch on when temperature drops, so at room temperature hi-limit should be on, (hear beep on tester), if there's no beep/continuity at room temperature, high-limit is faulty. disconnect power before doing any repairs, good luck.
