Possible Causes

Oversized unit for room, Thermostat sensor located too close to air outlet, Dirty filters causing rapid temperature swings, Refrigerant charge issues

How to Fix / Troubleshooting

Safety first: Turn off power before moving sensors or opening covers.

  • Step 1 – Check sensor placement:
    • Ensure the room sensor is not directly in the cold air stream.
    • Reposition within its holder if necessary so it senses return air.
  • Step 2 – Clean filters and coils:
    • Dirty filters can cause uneven cooling and rapid cycling; clean them.
  • Step 3 – Evaluate sizing:
    • If the unit cools the room very quickly and then shuts off, it may be oversized; consider using a lower fan speed or adjusting setpoint.
  • Step 4 – Technician check: If short cycling persists, a technician should check refrigerant charge and control logic.
