The AC compressor is a key part of your air conditioning system. When it doesn’t turn on, the entire system will not work. There are several possible causes for this problem, most of which are related to the electrical or mechanical systems that power the compressor. Below, you’ll find a few different reasons that your AC compressor might not be turning on. The most common reason is that the compressor’s capacitor is broken. Other possibilities include a loose connection or a blown fuse. Keep reading to learn more about the potential causes of your AC compressor not working.
Clean or replace your air filters as needed if they are dirty or clogged with debris.
One of the most common causes of an AC compressor not turning on is when the air filters are dirty or clogged with debris. If the air filters are not cleaned or replaced as needed, then the compressor will not turn on because it will not be able to function properly. There may even be a problem with the wiring or with the circuit breaker. If there is a problem with either of these, then the compressor will not turn on and will need to be fixed in order for the AC unit to start working again. You should always ensure that you get routine maintenance done on your AC by an HVAC professional.
Check to see if the breaker has tripped or if there’s a faulty capacitor.
There are a few reasons why an AC compressor may not turn on. One reason could be that the breaker has tripped or blown. If this is the case, it will need to be reset in order for the AC unit to start working again. Another potential issue could be a faulty capacitor. This component helps power the compressor, and if it’s not working correctly, the compressor may not turn on.
Inspect the wiring for any damage or corrosion.
Another one of the most common causes of a compressor not turning on is damage or corrosion to the wiring. This can be due to wear and tear, or if the compressor has been exposed to water or moisture. If there is any damage or corrosion to the wiring, it will need to be repaired in order for the compressor to work correctly. If there’s no power getting to the compressor, it may be due to a failed fuse, relay, or switch. Or it could be that there’s an issue with the wiring going to the compressor. And if there’s excessive vibration or noise coming from the compressor, it may be because something is jammed inside or it’s about to fail completely.
Verify that there is refrigerant in the system.
If the AC compressor is not turning on, it may be due to a lack of refrigerant in the system. When the AC compressor is not getting power, it will not turn on. If there is no refrigerant in the system, then there will be no power going to the compressor, and it will not turn on. One common cause is a lack of refrigerant in the system. This can be caused by a leak in the lines or seals around the compressor. If there isn’t enough refrigerant to keep it cool, the compressor won’t turn on.
In general, the compressor is one of the most important components of an air conditioning system. If the compressor does not turn on, the system will not work properly and the interior of the building will not be cooled. There are several possible causes of a compressor not turning on, and it is important to identify and correct the problem as soon as possible.
