Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power before moving sensors or opening covers.
Steps to check:
- 1. Clean filters and coil: Ensure good airflow to reduce rapid temperature changes at the sensor.
- 2. Check sensor placement: Confirm the T1 room sensor is in the return air stream, not touching the coil or near the supply outlet.
- 3. Avoid blocking airflow: Do not place curtains or furniture directly under the indoor unit.
When to call a technician: If short cycling persists, a technician should check sensor calibration, refrigerant charge, and confirm the unit is correctly sized and installed.
