Possible Causes
Compressor drawing excessive current, Shorted compressor windings, Failing fan motor causing high load, Defective current sensor on PCB
How to Fix / Troubleshooting
Safety first: Turn off and unplug the unit. If you smell burning or see smoke, do not restart the unit.
- 1. Check airflow and cleanliness: Clean filters, intake, and exhaust grilles. Poor airflow can increase compressor load.
- 2. Verify supply voltage: Use a multimeter (if qualified) to ensure the supply voltage is within the range specified on the rating plate. Low voltage can cause high current draw.
- 3. Listen to compressor: After cooling down, restart the unit and listen. If the compressor hums loudly and trips quickly, it may be mechanically seized or electrically shorted.
- 4. Do not bypass protection: Never attempt to bypass fuses, thermal protectors, or current sensors.
- 5. Call a technician: A professional should measure compressor current, check windings, and test the PCB current sensor. Compressor or PCB replacement may be necessary.
