3. Air conditioner E3 troubleshooting methods
For air conditioner E3 failure, you can follow the following steps to deal with it:
1. Preliminary inspection
First, check whether the power supply of the air conditioner is normal and whether the connecting wires of the indoor and outdoor units are loose or fallen off. If it is a communication failure, replugging and unplugging the signal cable may solve the problem.
2. Clean the radiator
If it is a high voltage protection problem, it may be caused by poor heat dissipation of the outdoor unit. After turning off the power, clean the outdoor unit radiator with a soft brush to ensure smooth ventilation.
3. Check the refrigerant
Too much or too little refrigerant may cause E3 failure. Professional maintenance personnel are required to use a pressure gauge to detect the refrigerant pressure and make appropriate adjustments.
4. Check the sensor
For sensor failures, it is necessary to check whether the relevant sensors are damaged and replace them with new ones if necessary.
5. Professional maintenance
