Camry air conditioner frequently turns on and off (short cycling)

Safety first: No high-voltage work is required for basic checks.

• 1. Check sensor placement: Ensure the room temperature sensor is near the air intake, not hanging in the cold air stream from the outlet.
• 2. Clean filters and coil: Dirty filters can cause rapid temperature changes at the sensor; clean them thoroughly.
• 3. Avoid obstructions: Do not place heat sources or electronics directly under the indoor unit.
• 4. Adjust setpoint: Set a moderate temperature to reduce rapid cycling.
• 5. PCB evaluation: If short cycling persists, a technician should evaluate the indoor PCB and sensor calibration.
