7 Reasons Why is my Aircon Not Working?

Troubleshooting the common aircon problems

There’s nothing more frustrating than your having your aircon not working on a hot day. As with any household appliance or device, you’re bound to run into aircon not working issues every now and again. There are quite a few different air conditioner problems that you can run into. Some are more common that others. Today we’ll take a look at the 7 reasons why is your aircon not working how to deal with them.

1. Aircon leaking problem

Leaks are quite possibly the most common of all aircon problems. These can be serious issues as they can contribute to water damage, mould growth, and other things. If you find that your aircon is leaking, you should first check your drain pan and confirm that it’s not rusted through. Next, you need to make sure that there aren’t any blockages within the drain that stop the water from properly reaching the drain pan. If you find the drain is clear, then it’s possible you have a frozen compressor causing the leak. At that point, it’s time to get some professional help. Read more on: aircon leaking water problems

2. Aircon freezing up problem

Another thing that could have your aircon not working is a frozen coil. If any of your coils freeze over, it can definitely interfere with the operation of your aircon. Fortunately, it’s not that difficult to keep your coils from freezing. Actually, the vast majority of freezing issues can be prevented by simply making sure your filters are changed every month as they should be. If this doesn’t solve the issue, then your problem could be a dirty evaporator, or you could just have low refrigerant levels in your aircon. Again, don’t attempt major repairs on your own.

3. Aircon compressor noisy problem

If you notice that your aircon compressor is noisy when it’s running, you might have a problem with the fan belt. Usually, this is a simple problem to fix as the belt has just been dislodged from the track. All you need to do to correct it is to simply pop it back in place. It might seem like a relatively minor aircon problem at first, but if left unchecked, it can eventually lead to your fan making very loud noises. It can also cause quite a bit of damage to the belt itself. Read this article to learn how to fix a noisy air conditioner. If you’re not comfortable fixing it on your own, don’t hesitate to get an aircon professional involved.

4. Aircon compressor not working

This is a fairly common issue that tends to occur near the beginning of each cooling season. What you need to do first is check whether there is any power going to the outdoor unit. Ensure that the disconnect switch is set to the ‘ON’ position. Once you verify this and there still isn’t any power, check that the breaker is properly working and that the wire for the disconnect switch isn’t burned out. Now, if none of those turn out to be your aircon problem, you may have either a defective contactor, transformer, or thermostat. You can have an electrician or professional HVAC technician diagnose the symptoms of your unit and recommend a course of action.

5. Aircon automatically turn off and on

If your aircon automatically turn off and on, this could be caused by a number of factors. First, you could simply be running low on aircon gas/coolant. That would cause your aircon to aircon automatically turn off and on more often. It could also be that your aircon unit is too large. This could mean it only cools in brief spurts, rather than more evenly as it should. Contact your aircon technician to figure out what issue you’re experiencing.

6. Aircon tripping the breaker

Sometimes you might encounter an issue in which the circuit breaker trips each time your aircon compressor turns on. This could be an indication of a weak circuit breaker. It could also be that there is a problem with the aircon itself, either a grounded compressor, defective contactor, or a shorted-out condenser fan. Either way, it’s something that needs to be fixed sooner rather than later.

7. Aircon thermostat problem

You might notice that your thermostat isn’t holding the correct temperature as it should be. This could just be a result of your thermostat’s calibration being defective. First, try to recalibrate your device and check whether or not that fixes the issue. If that doesn’t work, you may have to replace the thermostat altogether. Fortunately, it’s not an expensive component, so replacing it won’t hurt your wallet too badly.

Summary of common aircon problems

As you can see, there are a variety of aircon problems that can occur, from freezing coils to defective compressors to aircon leaks. Remember, the best protection is prevention. Knowing these issues and how they can occur can give you some idea of the things you can do to prevent them from occurring.
