Customer Questions and Answers for Dryer Thermal Cut-Off Kit by Whirlpool

SamH, First check and make sure both breakers/fuses are reset and you have 220 VAC at the wall outlet and the terminal block on the back of the dryer. Then check the door switch circuits and wires. You didn't supply a model number, but the basic wiring diagram indicates; the L2(red wire) is a "direct" link to the element, and terminal block, through the heat switch on the motor, and only affects the heater element. L1(black wire) supplies power to the drum light, and the circuit is completed through the door switch to the neutral leg(whit wire). You'll also need to check for L1 power to the timer. There are no fuses in the L1 circuit(except to the motor) but that wouldn't affect the drun light or power to the timer. Repost your question and include a model number Please, we can review the diagram and make a more proper diagnosis and help direct you to other possibilities. Thanks,
