Possible Causes

Overheating triggering thermal cutoff, intermittent power cord connection, failing main control board, fan slowing down and causing overheat

How to Fix / Troubleshooting

Safety First: Unplug the unit after an unexpected shutdown and allow it to cool before restarting.

Step-by-step checks:

  • Ventilation: Ensure the unit has adequate clearance and vents are not blocked. Overheating can cause safety cutoffs to trip.
  • Check cord and outlet: Wiggle the plug gently (with unit off) to see if there is any looseness. Try a different outlet.
  • Monitor fan: During a test cycle, listen for consistent fan speed. If the fan slows or stops before shutdown, see fan troubleshooting steps.
  • Thermal cutoff (advanced): With the unit unplugged, locate and test the thermal cutoff or high-limit thermostat for intermittent behavior (may require heating and cooling tests).
  • Replace components: Replace a weak high-limit thermostat, failing fan motor, or main control board if they are identified as the cause.

Note: Document when shutdowns occur (time into cycle, temperature setting) to help pinpoint overheating vs. power issues.
