The air conditioner appears E7
It is the air conditioner fault code and it is an overcurrent or phase sequence protection external feedback fault.
If it is not a new machine, it can be concluded that it is over-current protection. The over-current protection means that the voltage is low and the compressor starting capacitor can be replaced, which can basically solve the problem. This is a common problem with old air-conditioning machines. . And it has been raining a lot recently, so we encounter more of this kind of situation.
If it is a new air conditioner, follow the following methods for maintenance:
1. Check whether the power access methods of the internal and external machines are consistent. The hot and neutral wires must be connected to the corresponding positions. In addition, check whether the signal connection cables of the internal and external machines correspond one to one and cannot be misaligned;
2. Check the voltage. If the phase sequence is reversed, change the phase sequence of the external power cord.
