Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the unit before repositioning sensors or opening covers.
Steps:
- Filter and coil: Clean the air filter and check the evaporator coil for ice. If iced, let it thaw completely and correct airflow issues.
- Sensor placement: Locate the room temperature sensor. Ensure it is positioned in the return air stream, not directly in the cold discharge air.
- Room conditions: Avoid setting the temperature extremely low; set a moderate temperature and observe operation.
If short cycling continues with clean filters and proper sensor placement, a refrigerant or control issue may be present and should be evaluated by a technician.
