Possible Causes

Stuck heater relay on main control board, Shorted heating element to ground, Restricted airflow causing overheat, Failed high-limit thermostat not opening

How to Fix / Troubleshooting

Safety First: Unplug the dryer and shut off power at the breaker before inspection.

  • Check airflow:
    • Clean lint filter, lint housing, and exhaust vent thoroughly.
    • Ensure the vent hose is not crushed or kinked.
  • Inspect heating element for grounding:
    • Remove rear panel and access the heater housing.
    • Disconnect heater wires.
    • Measure resistance from each heater terminal to the metal heater housing; any continuity indicates a grounded element that must be replaced.
  • Check thermostats:
    • Test the high-limit thermostat and cycling thermostat for proper continuity and operation.
  • Inspect main control board:
    • Locate the heater relay on the control board.
    • Look for welded contacts (relay stuck closed) or burnt areas.
    • If the heater continues to heat when the dryer is off or in air-fluff, the relay is likely stuck and the control board must be replaced.
