Split AC Compressor Not Working But Fan Is Running

Check if the outside unit is on

The first step is to check if the outside unit is on. If it is, then check to see if the compressor is running. In case the compressor is not running, then it may be because the power is off or there may be a problem with the compressor itself.

If the power is off, then you will need to check the fuse box or circuit breaker to see if there has been a power outage in your area. In case there is no power outage, then you will need to check the wiring to see if there are any loose connections.

Check if you can see any lights around the outside unit

If the outdoor unit is running but the compressor isn’t, there could be a problem with the power supply to the outdoor unit. Check to see if there are any lights on around the outside unit. If you don’t see any lights, check your breaker box to see if the breaker for the air conditioner has tripped.

If it has, flips it back on and see if that fixes the problem. In case you still don’t see any lights, there could be a problem with the transformer that supplies power to the air conditioner. You’ll need to call an HVAC technician to come to take a look at it.

Check if it’s making any noises

If your compressor is making any noises, it could be an indication that something is wrong. First, check to see if the noise is coming from the compressor itself or from something else.

If it’s coming from the compressor, it could be a sign that the bearings are going bad. In this case, you’ll need to replace the compressor.

Check if it’s plugged in

Check if your unit is plugged in. If you have followed all of the steps above and your split AC compressor is still not working, then it is time to contact a professional for help. Do some research to find a reputable service person in your area.

Once you have found someone, give them a call and explain the situation. They will be able to help you troubleshoot the problem and get your AC unit up and running again in no time.

When your air conditioner is running but temperature inside does not drop, you may have a blocker condenser coil. When operating properly, the condenser fan draws air into the outdoor unit through the coil to remove heat from your home.

What to do if my compressor is not turning on?
