Question:

What is Error Code 81E or 81C and how can it be resolved?

Answer:

Error Code 81E or 81C refers to compressor starting failure. This issue may occur due to an abnormality in the Inverter PCB IPM operation (with voltage lower than DC 13.5V) or a short circuit in the compressor. To resolve this issue, first check the power supply to ensure proper voltage. If the voltage is stable, then check the compressor for any potential short circuits. After identifying and fixing the problem, try starting the compressor again.
