When using dryer in auto dry or perm press mode, timer won't shut off on it's own .Dryer dries fine. On fluff dry, timer will advance and shut off on it's own, but it also is heating in fluff dry mode. Shouldn't fluff dry, be operating without heat?
Is it a bad timer, or a bad cycling thermostat?
ANSWER Jim, Your first check should be the heating element Y313538 or Y308612 (depending on serial number) if it is shorted or grounded it will continue to heat on all settings, including air fluff, and this could cause the dryer timer to not advance in the auto cycles. The dryer has to heat properly in order for the timer to advance.
