Why is the air conditioner turned off when heating? Compare these reasons
There are many options for heating in winter than cooling in summer. Air conditioning heating is a relatively popular method, especially in wet and cold southern cities. Wearing more clothes most of the time actually cannot solve the fundamental problem. Air conditioning is the most comfortable choice, but Xiaobian believes that many friends should have encountered situations where the air conditioner automatically shuts down when it is heated. What caused this? How to solve it?
What is the reason for the automatic shutdown of air conditioning and heating
1. If the internal unit temperature sensor is damaged and cannot control the operation of the air conditioner, the air conditioner may automatically shut down. Open the outer shell of the indoor unit. There is a 3 to 4 cm copper sleeve on the copper tube coil inside and a tube temperature sensing probe. You can buy this at air conditioning repair points for a few yuan each.
2. If the air conditioner outlet filter is too dirty or the capacitance of the fan motor is aging, the air volume in the air conditioner will be greatly reduced. If a lot of heat cannot be brought indoors due to the blockage of the air conditioner filter during heating, it will cause the air conditioner compressor. When the exhaust temperature and exhaust pressure rise, the compressor will run overloaded. At this time, it is easy to shut down due to over-pressure protection or compressor overload protection.
3. It may also be that the circuit control components of the air conditioner are affected by moisture, dust accumulation, short circuit, etc. This problem will also cause the air conditioner to automatically shut down within a few minutes.
How to deal with air conditioning heating brake shutdown
1. Clean the blower filter of the indoor unit of the air conditioner, clean the dust on it, and dry the filter after cleaning.
2. Adjust the wind speed of the air conditioner, adjust the wind speed to high, medium and low respectively, and check whether the wind status is consistent with the wind speed.
3. If it is a problem with circuit control components, it is recommended that users not come out themselves. It is best to ask the air conditioner after-sales personnel to repair and replace the relevant damaged parts.
How to use air conditioning and heating correctly
1. The power supply voltage fluctuations should not be too large, that is, neither too large nor too small (±10% fluctuations are allowed). It is best to use dedicated line power supply for air conditioners, use single-phase three-hole sockets, and the sockets must be plugged in all the way when plugged in. Don’t just plug in half, which will easily leak electricity.
2. The enclosure of the indoor unit should be cleaned frequently. You can wipe it with a clean dry cloth or use a neutral detergent when the power is cut off. Remember not to rinse it directly with water.
3. The indoor temperature cannot be adjusted too low, as it will be uncomfortable for people, and should be set at an appropriate temperature.
4. Learn to use the timing function to achieve both energy saving and comfort.
5. There should not be too many people in the air-conditioned room, otherwise the cold heat will not be enough and the temperature will be difficult to rise.
6. Do not open and close the doors and windows of the room frequently, and people should not enter and exit frequently. Remember to close the door when entering and leaving to avoid loss of heat.
7. The glass windows should be closed tightly and tightly. It is best to hang a double black curtain inside, which can block the loss of heat and absorb some heat from external light.
8. When ventilation is needed indoors, the windows can be opened briefly for ventilation, but the window opening time generally does not exceed 10 minutes.
9. The filter inside the air conditioner needs to be cleaned regularly, otherwise the heating will be blocked from entering the room, which will cause insufficient air volume and deteriorate the heating effect of the room.
10. Don’t let the remote control be used as a toy for children to avoid damage. It’s best to place it in a place where children can’t reach it.
I suggest that everyone should clean up the air conditioner before winter and try it out. If problems occur, they will be discovered early and repaired early. Don’t wait until it is too cold to turn on the air conditioner. If something goes wrong, you will be frozen in vain.
