The F1 error code indicates an overcurrent condition or compressor protection issue. The system has detected excessive current being drawn by the compressor motor, which can cause damage if not addressed.
The compressor may be drawing too much current due to a malfunction.
Short circuits or wiring problems can trigger the overcurrent protection.
Obstructions in the refrigerant lines can cause excessive pressure, leading to an overcurrent condition.
Turn off the unit for 5–10 minutes and then turn it back on to reset the overcurrent protection.
Inspect the refrigerant lines for blockages.
Check the compressor motor for malfunction or wear.
