If you want to know how to troubleshoot your AC, you need to first understand what causes it to fail. You should check the thermostat, circuit breaker, air filter, and condenser. You should also check the thermostat if it has a programmable setting. If these do not work properly, then it is time to replace them.
Check the thermostat
There are several tests you can perform to identify a malfunctioning thermostat. These tests should be performed with the thermostat disconnected and the electrical outlet turned on.
The wiring for the thermostat is usually wrapped around the screws and labeled. To determine whether the thermostat is faulty, try performing a LOW VOLTAGE TRANSFORMER TEST. If you still cannot find the problem, try contacting a professional HVAC repair technician to diagnose and fix the problem.
The thermostat is a simple “on/off” switch, so any problem with it is likely to be caused by the control relay or switch in the equipment. A dirty thermostat may also cause the unit to cycle on and off, which is inefficient.
The simplest way to fix this is to clean the contactor and reinstall the thermostat. You can then repeat the test. After cleaning the contactor, check the wiring again and make sure the thermostat is clean.
A malfunctioning thermostat may make you think there’s something much more serious wrong with your AC. However, troubleshooting a malfunctioning thermostat is a great way to save money on the cost of hiring an HVAC technician. Thermostats are also easy to troubleshoot and often have a simple solution. If the thermostat has a problem with the wiring, replace it with a new one.
If you suspect that the thermostat is the cause of the malfunction, clean the area surrounding the unit using canned compressed air. After cleaning, examine the thermostat for any obvious malfunctions. If there’s any loose wiring or terminal screws, the thermostat may need to be replaced.

Check the circuit breaker
If you’re experiencing a power surge, one of the first things you need to do is check the circuit breaker. Sometimes the breaker has tripped and looks like it’s ON. This can happen for several reasons. For example, there could be a short in the wiring or a failed capacitor. These issues can cause the circuit breaker to trip, so it’s best to call a technician to look at the problem.
Your air conditioner may trip the circuit breaker if it’s not receiving enough electrical current. If it’s doing this frequently, you’ll need to call an electrician to fix the problem.
Also, you may need to have the wiring checked, or replace the AC. Check the circuit breaker as soon as you see any problems with your unit. Check it every time you have an electrical problem so that you can eliminate any potential risks and minimize your repair bill.
A tripped circuit breaker is a common problem. You may not even notice that it’s tripped until you try to turn on a fixture or appliance. To locate the tripped breaker, look at the main electrical service panel. You’ll notice that it’s in the “OFF” position and may have a warning label in red. You can reset the circuit breaker by flipping it back on.
If the AC’s circuit breaker trips, the problem could be a bad circuit breaker. It can happen because of the wear and tear on the breaker, or because the breaker was poorly installed. If it’s an older model, you may have a breaker that is too small. A good rule of thumb is to use the 80% ampacity rule to determine the proper size of the circuit breaker.
Check the air filter
If you’re having problems with the AC in your home, it’s best to check the air filter first. Dirty filters can prevent the air conditioner from blowing cold air. If the filter is dirty, the evaporator coils may become frozen, which can lead to reduced air flow. To keep your evaporator coils from freezing, clean the filter regularly with a soft brush and mild soap. You can also look at the motor or fan to see if they’re malfunctioning.
Changing the air filter is an easy way to prevent an AC malfunction. You can also check the fuses if you’re unsure of the proper wiring. But, it is better to call an air conditioning service to check the fuses. Professional HVAC technicians know how to check fuses and other components of the system in just a few minutes.
If you see a thick layer of dust around your air filter, it is highly likely that the air filter is clogged. You can tell this by looking at the dust around the vents. If the dust is higher than usual, the filter is dirty.
Another way to tell if the air filter is dirty is to try the “white sheet test”. You hang a clean white sheet near the vent. After a few hours, it should be gray. A dirty filter will clog the air ducts, which will make the air flow less effective.
Clogged air filters can also result in a decrease in the efficiency of your air conditioner. If your air filter is clogged, the air conditioner will have to work harder and spend more money to cool your home. The sluggish airflow will eventually damage the compressor. Luckily, a new air filter doesn’t cost much.
