How to Fix / Troubleshooting
Safety first: Turn off power before cleaning the outdoor unit.
- Step 1 – Clear surroundings: Ensure at least 30–50 cm clearance around the outdoor unit. Remove any obstructions.
- Step 2 – Clean condenser coil: Use a soft brush or low-pressure water to clean the coil fins thoroughly.
- Step 3 – Check outdoor fan: Confirm the fan runs at full speed when the compressor is on. Replace the fan motor if it is slow or intermittent.
- Step 4 – Technician check: If the unit still stops prematurely, a technician should measure compressor current and check the thermal protector and refrigerant charge.
