To fix this error code, you can try the following methods:

- Replace the compressor
You can try replacing the compressor. This will fix the error. Some compressors have a thermal cut-out switch. If the compressor is still under warranty, contact the compressor manufacturer for repair.
If the compressor is not under warranty, you can buy a new one from an auto parts store.
- Check the compressor wire for faults
You can check if there is any fault in the compressor wire. If there is a fault, replace it immediately to fix this error code.
They connect the wire to the compressor through a nut, so you need to remove the nut to disconnect the wire. You can find a service manual in your AC’s documentation or on the Internet.
It’s better to take out the entire wire from each place and then you can get it connected with a new one without damage. Once you get this disconnected wire, put it aside for future use.
