Customer Questions and Answers for Sensor Harness (Dryer Moisture Sensor) by Whirlpool

Andy, The moisture control system doesn't affect the start or program of the dryer. It senses the moisture in the clothes, in the drum and informs the control to advance to the end of cycle cool down and shut off. If the dryer is "dead" and can't be programmed then you want to check and reset the breakers in the panel box a few times and make sure you have 220 VAC at the terminal block on the back of the dryer. If the dryer display is illuminated, but the dryer won't start you'll need to check the thermal fuse, belt switch and 120 VAC at the machine control board. If the dryer is in a temperature controlled environment, then moisture inside the drum is due to an exhaust vent issue. You may want to disconnect the dryer exhaust vent from the dryer for a few days to verify the issue. You may also want to remove the lower front access panel and retrieve the tech data information sheet in order to test the control assembly and circuit test the other components of the dryer.
