This multi-temperature cycling thermostat regulates the dryer's drum heat, switching the heater on and off to match the temperature setting you choose. It can help restore consistent drying if temperatures are erratic, loads run too hot, or cycles take too long.

  • Maintains target temperature by opening and closing the heater circuit across multiple heat settings
  • Provides calibrated temperature control for safe, efficient drying
  • Failure may present as no heat or low heat, overheating, very long dry times, or inconsistent temperatures
  • Intended for models with multiple temperature selections
What's included: 1 cycling thermostat Install notes:
  • Unplug the dryer; shut off gas supply if applicable. Allow the appliance to cool before servicing.
  • Take a photo of wire positions; move wires to the new thermostat one at a time to matching terminals and ensure snug connections.
  • Remove/install mounting screws and seat the thermostat flat against the mating surface for proper sensing.
  • After reassembly, clear lint passages and verify proper vent airflow.
Diagnostic tips:
  • If there's no heat at all, also check the thermal fuse, high-limit thermostat, heating element (electric), or igniter/burner components (gas).
  • Restricted venting can mimic thermostat issues and cause overheating or long dry times.

Chris for Model Number LDE8300ACW

My dryer stopped heating, but continues to tumble and blow air normally. I have checked the hi limit switch and the two thermal fuses and all show continuity. When checking the cycling thermostat (wp307249) I get continuity between the outer contacts at room temperature, and open circuit at high temperature. The inner contacts however always show high resistance (approx 50k ohms). Is this correctly functioning? Are there any other components I should be testing?

Answer

Hello Chris, yes that is how it works, next check that there is 240v at the dryer's terminal block Black L1 to Red L2 with the dryer running, next check the heating element for correct resistance about 10-12 ohms, lastly if all checks are good, check that the heater is actually getting 240v at its terminals while running.
