Possible Causes

Overheating due to poor ventilation, Intermittent power connection, Loose thermistor connection causing false readings, Faulty control board

How to Fix / Troubleshooting

Safety first: Unplug the unit before inspecting wiring or moving it.

Steps to diagnose:

  • Improve airflow: Ensure proper clearance and clean the condenser and fan.
  • Check power cord and outlet: Wiggle the plug gently (with unit off) to ensure a snug fit. Avoid using loose adapters or power strips.
  • Inspect thermistor wiring: Loose temperature sensor connections can cause the board to think the unit is too hot or cold. Reseat connectors on the PCB.
  • Monitor behavior: After adjustments, run the unit and see if shutdowns persist. If so, the control board may be failing and require replacement.
