Cause analysis of P2 code problem in air conditioner
P2 (compressor top temperature protection)
The p2 fault code of the air conditioner indicates that there is a communication fault in the air conditioner. P2 fault occurred in the air conditioning circuit and the air conditioning system itself.
If the circuit board of the air conditioner fails, it is necessary to replace the damaged computer board of the air conditioner. If the air conditioning motherboard can't transmit information, it will also be removed. Of course, the air conditioner will not display p2 fault. Confirm whether the air-conditioning circuit board is damaged, and measure whether there is 220V current and voltage at the inlet and outlet of the air-conditioning circuit board with a multimeter. If it does not exist, the circuit board is damaged.
The outdoor power supply module of the air conditioner has loose wiring, which causes the air conditioner to display p2. In this case, it is enough to connect the disconnected line. In this case, the air conditioner needs to be disassembled, and the failure point can be confirmed by observing the module of the air conditioner. After processing, the air conditioner will not display p2.
Communication failure means that the connecting line between the outdoor unit and the indoor unit is propped up, so that the damaged line can be reconnected without p2 failure of the air conditioner. It is very normal for the air-conditioning circuit to fail, so it is ok to reinforce the connection.
