What does it mean when h5 appears on the air conditioner?

The air conditioner display "H5" usually indicates high temperature protection, evaporator temperature sensor failure or poor condenser heat dissipation. Solutions include lowering the room temperature, checking the sensor, or cleaning the condenser. If the problem cannot be solved by yourself, it is recommended to contact maintenance personnel.

The meaning of "H5" on the air conditioner display

"H5" on the air conditioner display usually means the following:

1. High temperature protection

• When the air conditioner is running, the indoor temperature is too high or the air conditioner load is too large, which will cause the compressor to overheat. At this time, the air conditioner will The high temperature protection function is automatically activated and "H5" is displayed to protect the compressor.

2. Evaporator temperature sensor failure

• The evaporator temperature sensor is responsible for detecting the evaporator temperature. If the sensor fails, the air conditioner cannot accurately sense evaporation. If the temperature of the air conditioner is lowered, the cooling effect of the air conditioner may be poor or the "H5" error may be displayed.

3. Poor heat dissipation of the condenser

• The condenser is responsible for heat dissipation. If the condenser heat dissipation is poor, it will cause the compressor to overheat and the air conditioner will display "H5" error.

Solution:

• Reduce the indoor temperature or reduce the air conditioning load.
• Check the evaporator temperature sensor. If it is faulty, replace the sensor.
• Clean the condenser and make sure it dissipates heat well.
• If you cannot solve it by yourself, it is recommended to contact professional maintenance personnel for inspection and repair.
