Customer Questions and Answers for Dryer Cycling Thermostat by Ge

Hello Kenn, I believe you will find that if the duct is removed from the rear of the unit, the timer will once again advance. If this is the case you will need to correct the dryers' ducting in the home that leads to outside atmosphere. This is a common issue and customers like to say the duct has been in place for years and cannot be the problem but the longer the duct is in place, the more lint accumulation restricting air flow is present. As per the manufacturer: Use rigid metal duct and exhaust the dryer to the outside by the shortest route possible. Dryer exhaust duct MUST NOT terminate under the home. Exhaust duct must not be connected to any other duct, vent or chimney. Venting materials are not supplied with the dryer. Do not use plastic or thin foil flexible ducting. Static pressure in the dryer’s exhaust duct should be no greater than .6 inches (1.5 cm). Check with dryer running and no load. Measure with a manometer placed on the exhaust duct approximately two feet (61 cm) from the dryer. For the best exhaust system Locate dryer so exhaust duct is as short as possible. Verify old ducts are cleaned before installing new dryer. Use 4" (10.2 cm) diameter rigid metal duct. Use as few elbows as possible. Use duct tape on all joints. Exhaust System Materials Exhaust duct must be four inches (10.2 cm) in diameter without obstructions. Rigid metal duct is recommended. DO NOT use plastic pipe, foil pipe, or flexible plastic pipe, because it contributes to poor drying performance and collects lint, which can lead to a fire hazard.
