You have relied on your air conditioner to keep you cool and dry in the hot and muggy summer months. But, when it breaks down, you may sweat profusely or your clothes become soggy. If your air conditioner isn’t working properly, there are a few things you should know. In some cases, can be an easy fix. However, if you can’t figure out what the problem is, you may need to call an air conditioning repair service.
Problems with the compressor
Compressors play an important role in keeping a home cool, so when they stop working properly, it could mean that your whole air conditioner needs repair. A poorly functioning compressor could also be causing other issues in the system. It may also have electrical problems. Electrical wiring in compressors can fray or corrode, causing problems with the flow of electricity. Another common problem with a compressor is overheating, which can be caused by a wiring problem or a faulty compressor motor.
If you suspect an issue with your air conditioner, you need to contact a licensed HVAC technician to diagnose the issue. You may be able to repair this issue yourself, but you should not try to replace the compressor until it has been replaced. Doing so may lead to an even bigger problem – causing you to spend more money in repair bills than necessary. Also, it is not advisable to attempt to repair a compressor by yourself if you don’t have the necessary training or experience.
Problems with the expansion valve
If you’ve noticed your air conditioning system has started to perform poorly, you should consider repairing the expansion valve. A bad expansion valve allows freon to escape the air conditioner and leak into the atmosphere, causing it to overheat and perform poorly. If you suspect your air conditioner’s expansion valve is faulty, contact a professional to assess your system and make the proper repairs. If you can’t fix it yourself, here are some helpful tips.
First of all, check Mini Split AC the refrigerant levels of your air conditioning system. If the level is low, the expansion valve will cause warm air to come out of the vents. If the refrigerant level is high, you can add more Freon to the system, but you should always check the expansion valve to determine whether you need to replace the unit. It may need to be replaced if you find the problem early enough.
Problems with the fan motor
To troubleshoot problems with the fan motor in an air conditioner, check if the windings are open or short. Measure the resistance of the fan motor to determine if it needs to be replaced. Most fan motors use a capacitor to help them run. Faulty capacitors can also cause the blower wheel or the fan belt to stop working. If you notice any of these symptoms, you may have a problem with the fan motor.
A malfunctioning fan motor may also occur if the relay switch in the air conditioning is stuck. If the relay switch is stuck, electric power will not reach the fan motor. If the fan is slow to spin, you may need to lubricate the motor bearings. The capacitor may have failed, too. Once you’ve fixed these problems, the fan motor in your air conditioner should start operating at full speed.
