whirlpool washer not completing cycles
my whirlpool estate clothes washer is not completing teh wash cycles. i hear a buzzing coming from the panel behind the controls. i can lift the knob, and turn it a few clicks and it will resume. i don't want to assume its a faulty control,but if it is, what does it cost and can it be the problem? it complete 80% of the cycle, ususally stopping during the rinse.
