The press failure of the air conditioner remote control is caused by the internal failure of the remote control. Check whether the air conditioner remote control is faulty, and check whether the positive and negative spring plates of the battery are corroded and rusted, resulting in poor power contact of the remote control. If so, use a blade or sandpaper to scrape away the rusty place and replace the battery. If the air conditioner remote control still cannot be used, check whether there is a problem with the crystal vibration in the air conditioner remote control that is easy to wear. If it can be replaced. After checking the crystal oscillator, check whether the LED of the remote control is damaged. At this time, the output voltage of the remote control integrated block can be measured with a multimeter. If the voltage changes, it indicates that the dust removal block has signal output and the infrared emission tube has a problem. If the voltage does not change, the integrated circuit will be damaged. In this case, you can directly replace the remote control. The reason why the air conditioner remote control does not respond may also be that the remote control has too much dust, or the conductive rubber is aging, resulting in poor contact of the remote control. At this time, you only need to wipe the remote control with alcohol and replace its conductive rubber. You can also add a layer of tin foil on the conductive rubber to improve its conductivity.

1. Determine whether your air conditioner power socket is powered. If there is no power, repair the power supply.
2. If the power supply is normal and cannot be started through the remote control, please turn on the manual switch on the air conditioning panel by hand. If it can be started, it means that the remote control or reception board is faulty. Find the manufacturer to replace the parts.
3. If the manual switch cannot be opened, it means that the main control board of the air conditioner is faulty. Mainly check whether the fuse is burnt out, whether the transformer is in good condition, and whether the rectifier power supply is in good condition. These require professional personnel to operate. 4. The fuse in the special circuit of the air conditioner is burnt out, or the power switch is in poor contact, or the power phase is insufficient. At present, due to the abnormal operation of other electrical appliances, many users use a power supply, resulting in abnormal power supply.
