On a sweltering day, many of us put tremendous faith in our cooling systems, hoping they will keep us comfortable. So if it seems like your air conditioner is struggling to complete a normal cooling cycle, it can be easy to worry.
Unfortunately, short cycling is one of the most common AC problems that homeowners can experience. There can be many reasons why your air conditioner turns off by itself, so it may take some troubleshooting before you understand what course of action needs to be taken.
Let’s discuss some potential reasons why your AC keeps shutting off.
Frozen Evaporator Coils
If your AC keeps shutting off and you don’t know why, consider turning your attention to the unit’s evaporator coils. These play a prominent role in air conditioning systems but, unfortunately, if they become frozen, it can cause your air conditioner to turn off unexpectedly.
Use this guide to find out what can cause evaporator coils to develop a layer of ice:
Dirty Air Filters
The air filter in your AC system has an important job in that it’s responsible for collecting airborne contaminants. When this filter is clean, it will help prevent harmful pollutants from getting recirculated into your home.
However, if this filter is dirty or clogged, it can spell many problems for your cooling system and your comfort. In fact, a clogged air filter could be one of the reasons why your air conditioner turns off by itself.
Dirty air filters can restrict the airflow coming and going from the AC unit. The air conditioner will need to work harder to overcome this obstacle, which can result in higher energy bills and short cycling. The equipment in your AC unit can also experience excessive wear and tear, which can lead to costly repairs or a replacement.
If your AC keeps shutting off, your instinct is probably to blame the air conditioner for the problem. However, your thermostat could actually be to blame instead. If your thermostat is located in a cooler part of your home, the AC unit may shut off too soon, thinking that it’s completed its job in cooling your home. A professional technician can help you move the thermostat to a more suitable location.
Oversized AC Unit
Did you know that an oversized unit could be one of the reasons why your air conditioner turns off by itself? It’s crucial for homeowners to ensure their air conditioning units are appropriately sized for their homes. Installing a system that’s too big or too small can lead to several problems, including short cycling.
For instance, if the unit is too big, it will end up cooling your home too quickly. The unit will shut off as a result, stopping in the middle of a refrigerant cycle. You may also find yourself paying for sudden AC repairs, as this frequent stop-start cycle can put excess stress on the unit.
Malfunctioning Run Capacitor
Air conditioners have a critical component known as the “run capacitor,” which is responsible for giving the cooling system the energy it needs to start operating. Unfortunately, the run capacitor can fail over time. As you can imagine, this problem could be why your AC keeps shutting off. Your air conditioner will only get the power it needs to keep running at sporadic times.
