Learn these methods, you are not afraid that the air-conditioning heating effect is not good!

The winter has come, and the air conditioner is used again. I originally expected the air conditioner for heating. Who knows that the air conditioner in the house does not heat up. What should I do? Find an air conditioner master, who will troubleshoot the problem in 1 minute, and it will be repaired soon. By the way, he also helped us popularize the knowledge that the air conditioner does not heat up. Let's take the posture up together.

1. Too much dust causes no heating

The air conditioner is clean for a long time, and the filter enters too much dust and blocks the air circulation. The air conditioner The heat inside cannot be taken out by the flowing air, resulting in no heating. Solution: Clean the air conditioner and filter.

2. Insufficient fluorine in the air conditioner leads to insufficient heat

If the air conditioner in the home has been used for about three years, the air conditioner has been moved before, but the air conditioner is not working now. Hot, it may be that the air conditioner is not fluorine enough. Solution: Find the after-sales service personnel of the air conditioner manufacturer to add fluoride to the air conditioner.

3. The solenoid of the four-way valve is broken

heat. If the solenoid valve of the four-way valve is broken, it indicates insufficient heating or cooling. Solution: The four-way valve solenoid is not very expensive. If it is broken, you can find an air conditioner repairer to repair it. Those who are knowledgeable can also solve it by themselves.

4. The voltage is too low or unstable, resulting in no heating

The air conditioner will use the point-in heating technology. If it is too elegant, it may turn on The time is too long for the temperature to rise. Solution: Wait for the voltage to stabilize before testing the air conditioner. If the voltage is stable and still not heating, you should consider whether it is an electrical auxiliary heating element.

5. The defrosting controller fails

If the air conditioner cannot switch to the defrosting state in time, frosting of the evaporator will occur when the heat pump is heating. This phenomenon affects the heat exchange efficiency of the air conditioner heating, resulting in insufficient heating capacity and even shutdown. It should be emphatically observed whether the defrosting temperature sensing device is misaligned, the contacts are sticky or poorly contacted, the fan impeller is slipping or the air duct is blocked, and the solenoid valve or the starting relay is invalid.

6. Insufficient refrigerant

Due to the leakage of the refrigeration system, the refrigerant that participates in the thermal cycle in the system is insufficient, resulting in a decrease in heat exchange efficiency, resulting in a system Insufficient heat phenomenon. Solution: Repair the leaking refrigerant by welding, and then replenish the refrigerant of the air conditioner.

Reminder: If the air conditioner is to be used normally, daily cleaning and maintenance are indispensable. In addition, if you need to perform in-depth maintenance of the air conditioner, it is recommended that professional and technical personnel perform thorough cleaning and maintenance of the core components of the air conditioner from the inside to the outside, so as to discover hidden problems in the air conditioner in time, effectively prolong its service life, and be healthier and more energy-saving. In-depth maintenance of the air conditioner is generally sufficient once every 2-3 years.
