How can I prevent the P5 error from occurring again after it has been fixed on my Mitsubishi air conditioner?

To prevent the P5 error from recurring, regular maintenance is crucial. Ensure that the outdoor unit is kept clean and free from debris, which can affect overall system performance and lead to overheating. Periodically inspect visible wiring for any signs of wear or damage. Professional annual servicing can also help, as technicians can check electrical connections, sensor integrity, refrigerant levels, and clean coils, all of which contribute to the longevity and proper functioning of critical components like thermistors and the compressor.
