The air conditioner can't turn on the heating mode.

The reasons why the air conditioner can't turn on the heating mode are power supply problem, air conditioner filter screen blockage, and air conditioner internal parts damage.

1, power problem

If the power cord plug of the air conditioner is not plugged properly or there is something wrong with the power cord, the air conditioner will not work normally. So, first of all, check whether the power cord is plugged in and damaged. If it is damaged, a new power cord needs to be replaced.

2. The air conditioning filter is blocked

If the filter screen of the air conditioner is blocked, it will affect the heating effect of the air conditioner. Therefore, cleaning the filter screen of the air conditioner regularly can keep the air conditioner in good working condition and improve the heating effect.

3. The internal parts of the air conditioner are damaged

If the components inside the air conditioner are damaged, such as heat exchanger and condenser, it will also affect the heating effect of the air conditioner. This situation requires professional maintenance. After maintenance, the heating effect of the air conditioner should be able to return to normal.

Precautions for use

Almost everyone knows that the doors and windows should be closed when the air conditioner is turned on. The purpose of closing the doors and windows is to increase the thermal insulation capacity of the room and extend the downtime of the air conditioner.

Another point that users often overlook is humidity. The greater the humidity, the slower the heat dissipation rate. Accordingly, the heat preservation effect will be better. Especially when air conditioning is used for heating, the room will be very dry. At this time, turn on the humidifier, or put a basin of water to ensure the indoor humidity, and people will feel more comfortable and save electricity inside.

5min In addition, due to the continuous low temperature, when the outdoor temperature is lower than 0 degrees, frequent defrosting will occur, generally 1- 1.5h, and the defrosting time is about 5 minutes. However, if the outdoor temperature is low and the humidity is high, the shorter the defrosting interval, the more frequent it will be.

It is normal that the air conditioner does not blow during this period. After defrosting, the air conditioner will automatically switch to heating operation, and at the same time, the air conditioner will have a "poof" sound when defrosting, which is the reversing sound of the four-way valve when defrosting, which is normal.
