What’s the reason why the air conditioner can’t start? Most of them are caused by these reasons

In summer and winter, I feel unhappy without leaving the air conditioner, especially when I was about to use the air conditioner, but the air conditioner couldn’t be turned on. It’s really distressing. What is the reason why the air conditioner cannot be turned on? This article summarizes these reasons based on the maintenance experience of the maintenance master for many years.

1. Do not clean the air conditioner for a long time

If the air conditioner is not cleaned for a long time, accumulated dust and dirt will reduce the air exchange rate, block the evaporator fins, drainage grooves, drainage holes, etc., affect operating efficiency, greatly increase energy consumption, and even cause circuit overload, posing safety hazards. However, cleaning air conditioners is a “technical job”. Don’t clean them yourself if you don’t know how to do it. Ask for help from professionals.

2. Power supply problems make it difficult to start the compressor

The power supply used in the air conditioner is aging, has poor contact, or the power supply is too low. When the voltage is lower than 10% of the single-phase normal voltage (220V), that is, 198V or below, the refrigeration compressor of the air conditioner is difficult to start. If the local power supply voltage is often in a low state, a reliable power supply regulator should be used.

3. The fuse is blown

If the fuse in the circuit dedicated to the air conditioner is blown, the air conditioner will definitely not be able to start. At this time, we must first check the reason why the fuses inside and outside the air conditioner are blown, and take measures to prevent them from blowing again, and adjust and repair them in a timely manner. Many homes use one power supply for power, and maintenance masters suggest that families with air conditioners should use a dedicated power supply for power supply.

4. The compressor is damaged

When installing an air conditioner, if the air in the system is not exhausted completely and ice jams occur, the compressor load will increase. The increase in the compressor load causes the compressor temperature to increase. The refrigerator oil will deteriorate for a long time at high temperatures and will not function in lubrication and cooling, which will promote the compressor temperature to rise further. The coil insulation is reduced due to high temperature, causing damage to the compressor. Therefore, when installing air conditioners, you must control the quality.

The above are the common reasons why the air conditioner cannot be started. When the air conditioner cannot be started, the first thing to be sure is whether there is a problem with the power supply and whether the plugs are plugged in. If the air conditioner still cannot be started even when the power is on, do not disassemble the air conditioner yourself. It is best to immediately let the maintenance master come to check and repair it.
