3387134 cycling thermostat is in tune with the temperature of your dryer and regulates it in order to maintain a certain temperature. This thermostat reaches a temperature of 155 degrees, turns off, and then turns on again once it has dropped by 25 degrees. If your dryer is not giving off enough heat, is over-heating, is not turning on, or is having issues with the timer functionality, it could indicate an issue with the thermostat. The installation of the cycling thermostat is simple and the only tool required is a 1/4 inch nut driver (and gloves for safety).Replaces the following part numbers: 306910, 3387134, 3387135, 3387139, WP3387134VP.Works for brands: Whirlpool, Kenmore, Maytag, KitchenAid, Roper, Crosley, Estate, Amana, Inglis, Admiral, Magic Chef, Jenn-Air.Fit Models: Kenmore 11060012000, 11060012001, 11060012002 etcFixes problem with: No heat or not enough heat Takes too long to dry Will Not Start Timer will not advanceContact Us If you are not sure if part is correct, ask us in Customer questions & answers section or contact us by visiting the Discount Parts Direct storefront.Business Wholesale We are a small local company from Houston, Texas offer discount parts for retail and wholesale.
