Midea P2: the compressor top temperature protection has acted

What Does Error P2 Mean?

Midea gives P2 as compressor top temperature protection. A sensor on the compressor shell has reported a temperature above what the control permits, and operation has stopped to keep the motor and its lubricant inside their design range. It is a protection acting correctly, not a declaration that the compressor has failed. Applies to: Midea residential split air conditioners and heat pumps covered by the Midea online troubleshooting code reference Midea builds equipment for several brand programmes alongside its own range, and code assignments vary between them. This reading applies to Midea-branded residential split equipment covered by the Midea troubleshooting reference; a P2 on a unit sold under another name follows that brand's documentation. Owner-safe checks: Stop calling for operation and leave the system off so the compressor is not repeatedly restarted into the same condition. | Isolate the outdoor unit at its dedicated switch, then clear leaves, cuttings, and vegetation from around the casing without touching the coil fins. | Note the outdoor temperature at each stop and how the system had been performing in the weeks before. Qualified technician: Charge measurement, leak detection, coil cleaning, and shell sensor testing are certified refrigerant and electrical tasks. | Never add refrigerant without finding where the previous charge went, and never wash or comb an outdoor coil without the training to avoid damaging the fins.
