Customer Questions and Answers for Washer Timer by Whirlpool

Karin, You would need to carefully check for 120 VAC into the timer (L!-black wire) then check for 120 VAC out of the timer (SW-black wire) to the lid switch, no voltage on either check would indicate a failed timer or no voltage from the outlet/power cord. If OK, then check for voltage on the SW terminal of the lid switch(double black wires). close the lid and check for 120 VAC on the red wire on the "check" switch,if no voltage replace the lid switch assembly.
