Possible Causes

Oversized unit for room size, Thermistor (T1) sensing return air incorrectly, Dirty filters causing rapid temperature swings, Incorrect installation location (thermostat too close to supply air)

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.
