Roper washer doesn't spin and drain it also doesn't make a humming noise. Model # 17A21XO3B or 17A21X03B. The washer runs just fine when its first started it fills and agitates just fine, u can also here a normal humming sound when its started. But when it get to the spin cycle it just stops running and there is no humming sound. I have read that it could be the lid switch, how can i check to find out if its the lid switch? Also could it be the main control unit? Hoping its a cheap fix.
