You answered my question about my dryer it works fine on timed dry as I have heat & it dries clothes and turns off, however, on auto-sense it has heat, it drys clothes, but the dial does not move. It just keeps running. The dial won't advance to off. You said to, it could be the resister part #279872, however, under the compatable section it says this part is not compatable with my dryer. Can I use it anyway?
Answer Hello Michael,
This is an issue of air flow. You need to check the entire exhaust duct for clogs and crimps. When the unit cannot exhaust the moist air, it is blown past the drum seals and released directly back into the cabinet. This makes the sensors continue to pick up the moisture and the timer will not advance. The duct should also be as short as possible. To verify that this is correct information, remove the exhaust duct and turn the unit on, on an auto-dry setting. Within about 5 minutes, you will be able to tell that the timer has begun to advance.
As far as the resistor 279872 goes, it can be at fault, but if you test it with a resistance meter set to the proper scale to read up to 5000O, (or 5KO.....same thing), This resistor should give a reading between 4050O and 4950O. If the reading you get is between these readings, the issue is the exhaust duct. And, by the way, this resistor is the satisfactory substitution as recommended by the manufacturer. Our compatibility tool does not always recognize crossed or substituted parts.
