Air conditioner Shenhua brand air conditioning heating always stops at what is the reason for starti

1. The air conditioner is in defrosting work.

If the air conditioner is starting to defrost, the air conditioner will not continue to supply air at this time, and the air conditioner will also shut down. After the temperature is turned back up, the air conditioner starts heating again, or after the baffle is facing down, the air conditioner also starts to heat, then it means that the air conditioner is defrosting.

Therefore, there will be the phenomenon of air conditioning heating stopping, this time there is no need for any operation, and after the defrosting of the air conditioner is completed, the air conditioner will naturally start heating again. There is no need to worry about this.

Second, the air outlet is facing upward.

Some users will use the blower while using the air conditioner in winter, because the hot air is rising, so the air in the upper part of the room is hot air, and the lower part is still relatively cold, the air conditioner has a thermostat, the general position of the thermostat is in the upper part, when the temperature around the thermostat reaches the set standard, the thermostat will automatically stop. When the room does not need to be heated, the air conditioner automatically turns off. To avoid these problems, the air outlet should be facing down when using the air conditioner.

3. The air conditioner reaches the set temperature.

If the air conditioner stops suddenly during the heating process, it may be because the set temperature is reached, the user can check whether the heating set temperature of the air conditioner is not adjusted, whether the set temperature is too low, when the air conditioner reaches the set temperature standard, the air conditioner will stop supplying air, that is, automatically stop heating. We just need to turn up the set temperature of the air conditioner a little so that the air conditioner will work automatically after a while.

Fourth, the heating parts of the air conditioner are damaged.

If none of the above is true, it is likely that the components heated by the air conditioner will suddenly fail, such as short circuit, high voltage, etc., which may lead to damage to the components. It may also be due to the deterioration of the internal heating parts of the air conditioner after long-term use. It is recommended that the air conditioner maintenance personnel come for maintenance and do not turn on the air conditioner without authorization.

The repeated start of the heating of the air conditioner of the Shenhua brand is due to the fact that the outdoor temperature is too low and the air conditioner is repeatedly defrosted, resulting in repeated stopping.

When the outside temperature is lower than 5 degrees, the outside machine will freeze, and it needs to be stopped frequently to defrost, and the heating will be automatically resumed after defrosting, which is the characteristic of heat pump air conditioning, not machine failure. If the air conditioner is defrosted more frequently, clean the filter screen of the inner unit, and adjust the temperature to a higher level.

When the air conditioner is cold, because the user sets a high temperature for heating in combination with the environmental needs, it will cause the outdoor unit to frost quickly, and the air conditioner will stop supplying air, so the air conditioner will shut down. Therefore do not set the temperature too high in winter, it should be 18 20 in winter. The temperature of the air conditioner should not be too different between indoor and outdoor, generally 5 10 is appropriate.

Cold weather will seriously affect the normal performance of the cooling and heating function of the air conditioner. For heat pump air conditioners with automatic defrosting, the minimum ambient temperature used is also -5, below which it is not effective for heating.

1. Check whether the set temperature is close to the ambient temperature; 2. Whether it is caused by the low outlet temperature and the cold air of the indoor unit; 3. The freon of the system is insufficient, and the condenser of the outdoor unit is frequently shut down for defrosting;

If the air conditioner is in defrosting work and the heating is interrupted, it is also possible that the air outlet is facing upwards and the thermostat is working, and the set temperature of the air conditioner is too low or the heating parts are damaged, which will cause the air conditioner to stop heating, and targeted maintenance can be done. Solution: 1. If the air conditioner is starting to defrost, it means that the air conditioner will not supply air, then the air conditioner is in a shutdown state, then, the air conditioner will not heat at this time, at this time, we can put the baffle down, the air conditioner will start to heat, if this is the reason, after the air conditioner is defrosted, it will automatically return to heat, do not worry about this failure.

2. The air outlet is facing upward, the thermostat of the general air conditioner is at the top of the air conditioner, then, if the air outlet is facing up, it will cause the hot air to be at the top of the room, then the room is cold, but the thermostat feels the high temperature, the air conditioner will stop working, at this time, you only need to put the air outlet downward. 3. Check the set temperature of the air conditioner to see if the temperature of the air conditioner is too low, resulting in the failure to achieve the heating effect. 4. If the above are excluded and there is no problem, then the rough mold is considered to be damaged by the heating parts of the air conditioner, and a professional maintenance master can come to repair it.

Note: There may be many reasons why the air conditioner does not heat, so you can check them one by one.

Shenhua air conditioner does not work when it is turned on, (1) Cause analysis The fuse in the special circuit of the air conditioner is blown out, or the contact of the power switch is poor, or the power supply is out of phase. At present, many users use a power supply in combination, and the power supply is abnormal due to the abnormal operation of other electrical appliances. The power supply used by the air conditioner is too low, and when the voltage is less than 10% of the single-phase normal voltage (220V), i.e. 198V or below, the refrigeration compressor in the air conditioner is difficult to start.

If the knob on the temperature controller is not dialed to the appropriate position, if it is dialed to a higher position, when the power supply is connected, the temperature in the air conditioning room has not reached the upper limit of the set temperature (the temperature at the starting point), and the compressor cannot start running. High pressure relay action, such as the condensing pressure is too high, so that the high pressure relay acts, stopping the operation of the compressor. Low-pressure relay action, such as insufficient refrigerant in the refrigeration system, resulting in the compressor suction pressure is too low, so that the low-pressure relay action stops the operation of the compressor.

When the current of the compressor and fan motor is too large, the power supply is cut off by the overload protection relay. (2) Elimination method First check the cause of the fuse inside and outside the air conditioner, and do a good job of preventing the re-burning of the measures are not good, should be adjusted and repaired in time. It is recommended that households with air conditioners should set up a dedicated power supply to prevent this kind of failure.

If the local power supply voltage is often in a low state, it should be used with reliable power supply regulation, and at the same time, it is recommended that families with more household appliances use a special power supply. Adjust the knob on the temperature controller to the desired position to lift the excitation, that is, adjust it according to the temperature required by the air-conditioned room. Check the cause of the high condensation pressure and rule it out so that the condensing pressure can be restored to normal pressure.

Check the cause of the refrigerant shortage in the refrigeration system and rule it out so that the suction pressure can be restored to normal pressure. Check the cause of overload of compressor motor and fan motor, and eliminate it; Press the Reset Button of the Protective Relay. Hope it helps.
