Troubleshot entire power circuit. Ohms/continuity checked door switch, motor start and run windings, thermal switch and broken belt switch. Even though the drive belt did not break, I found the broken belt switch failed. Meter cked open when should have read continuity/closed. Ordered part from AppliancePartsPros (cheaper than Whirlpool for same part) on a Wednesday night around 9 p.m. and had new part in my hand by 2 p.m. Friday of the same week....20 minutes later, and the dryer is runnin like a champ...Couldn't be happier, and the wife is impressed...BONUS!
