How to solve the air conditioner display e 1?

E 1 Solutions for air conditioner display include restarting air conditioner, checking air conditioner temperature sensor, adding refrigeration oil, etc.

1, restart the air conditioner.

Try to restart the air conditioner first, turn off the power supply of the air conditioner, and wait for about 5 minutes before restarting. This will clear the past fault codes and reset the air conditioning system, which is sometimes enough to solve the problem.

2. Check the air conditioning temperature sensor.

If e 1 is still displayed after restarting, it may be that the temperature sensor of the air conditioner has failed. In this case, it is necessary to check whether there are sundries or dust inside the indoor unit of the air conditioner, and clean it if necessary. Then check whether the temperature sensor is in good contact with the air conditioner. If it is loose, it needs to be reinserted.

3. Add refrigeration oil

When the air conditioner shows the fault sign of e 1, it is likely that there is something wrong with its compressor. Insufficient refrigerant oil in the compressor cylinder will cause the sign of e 1. If there is a shortage of refrigeration oil, just add some refrigeration oil.

The reason why the air conditioner displays e 1 may be that

1. e 1 appears in the air conditioner. If the compressor is stuck or the refrigeration oil is not enough, you can add enough refrigeration oil to the air conditioner. After adding it, restart the air conditioner and it will return to normal.

2. The air conditioner appears e 1, probably because the refrigeration mechanism is blocked and the branch pipe is blocked, so the pressure will rise and the compressor exhaust temperature will rise. When the compressor is overheated, it will stop for protection.

3. e 1 appears in the air conditioner, probably because the heat sink of the outdoor unit of the air conditioner is blocked, the heat sink can't work normally, the heat of the outdoor unit can't be discharged, and the outdoor unit is overheated, which will also protect the shutdown.

4. The air conditioner appears e 1, probably because the air fan blade is damaged and can't work normally, resulting in the heat of the compressor can't be released normally. If the temperature is too high, it will stop the machine protection.
