How to Fix / Troubleshooting
Safety: Unplug the unit and allow it to cool if it feels hot to the touch.
Steps:
- Improve airflow: Ensure adequate clearance around the unit and clean the condenser coil.
- Check ambient conditions: Move the unit away from heat sources and ensure room temperature is within spec.
- Inspect sensors: Check the ambient and evaporator sensors for secure mounting and intact wiring as described in the E1 and E2 procedures.
- Monitor operation: After corrections, run the unit and observe whether it still shuts down prematurely. If so, the control board may be misreading sensors and require replacement.
