dryer runs constantly in all settings, heats and dryies ok but never shts off until door is opened. is this the timer? and if i buy one and it turns out not to be, can i return it
I never got a refund on a timer once it was out of a sealed container it came in.
Check the paper wiring diagram you'll find in the control panel, look for a resistor and have some one check it for you. If bad the dryer timer won't stop, replace it
Timer?
