Over Current Error (CT Error) Troubleshooting Checklist
- Check for clogged fins on the heat exchanger and/or obstructions in the air passages.
- If no obstructions are found proceed to ohm the condenser fan motor. The compressor should also be ohmed out as well.
- If fan motor ohms within proper readings replace the Main Control board.
- If the Main Control board has already been replaced then replace the compressor, Main Control board, IPM and ACTPM boards.
- Also, verify line sets!
