What to do if my Fujitsu Air Conditioner shows an IPM protection error?

If your Fujitsu Air Conditioner displays an IPM protection error, it could be due to the following reasons: * Blocked heat radiation (inlet/outlet): Ensure that there are no obstructions blocking the inlet or outlet. * Defective outdoor fan: Check if the outdoor fan is working correctly and rotating properly. * Open valves: Verify that the 2-way or 3-way valve is not left open. * Compressor issues: Inspect the compressor's winding resistance value and check for any loose lead wires.
