AC Won’t Turn On? Here Are 5 Reasons This May Be Happening

In 1913, Death Valley California set a new record when temperatures hit an all-time high of 134°. While the temperature this summer may not reach quite as high, chances are you want to take advantage of your air conditioning to keep your home cool and comfortable, which is why noticing that your AC won’t turn on can be an incredibly frustrating experience.

If you want to save yourself from looking like a melted popsicle this summer, here is a list of reasons why your AC won’t turn on and what to do about it.

Reasons Why Your AC Won’t Turn On

If your AC won’t turn on, don’t stress out and head straight to the store to replace it. There are some potential reasons why this may be occurring, and you’ll find that some of them are even easy to solve.

By simply investing some time into troubleshooting your AC, you may find that you’re able to keep cool after all.

Checking Your Circuit Breaker

Circuit breakers tend to be one of the most common reasons why an AC won’t turn on. This is due to the fact that circuit breakers are programmed to turn off when they’re overloaded with too much electricity. While this may seem like an inconvenience, it’s actually a way that the device protects your home from any potential fire hazards.

A simple way to check if this is the cause of your AC malfunctioning is by taking a look at whether or not other electrical devices have also shut down. In this event, you may need to reset your breaker and unplug any unnecessary electrical items that consume too much electricity

A Blown Fuse

While you may suspect that a blown fuse is the cause of your AC not turning on, you’re going to need a multimeter to find out for sure. With a multimeter, you’ll be able to perform a continuation test to check out the fuses to see if they’re providing adequate amounts of electricity.

If you’ve done the test and don’t hear the multimeter beep, you may need to purchase a replacement fuse at your local hardware store.

A Clogged Air Filter

Many homeowners are unaware of the fact that they actually need to change their air filters on their air conditioners regularly. However, it is an important part of maintaining a fully functioning AC unit.

Your air conditioner needs to filter out clean air in order for proper air flow to occur. However, if the AC filter takes in too much debris, dust, or dirt, the air will be obstructed and trapped within the AC making it difficult to hold.

You can usually tell this is the case by seeing water droplets in the condescension tray or in the drain lines.

Dirty Evaporator Coils

When we say it’s important to be sure that your AC is being kept clean and well-maintained, we mean it.

Not only can an air filter be the cause of the malfunctioning AC unit, but dirty evaporator coils can also lead to similar results. Our homes collect an overwhelming amount of dander and dust on a daily basis. Many of this debris can easily end up in the evaporator coils of your AC unit.

When too much debris builds up within the coils, it can start to affect the different components within your AC unit. Eventually, this will lead to a full breakdown that can only be fixed by replacing the entire unit.

Dirty Condenser Lines

Similar to your evaporator coils, your condenser lines need to be kept clean in order to function the way they’re designed to. This is particularly dangerous as condenser lines tend to accumulate mold and algae, which tends to attract birds or rodents that view the spot as an ideal place to nest.

Not only will this lead to a malfunctioning AC unit, but it will also increase the likelihood of a pretty nasty rat infestation if you don’t stay on top of things.

Refrigerant Leak

Similar to your car’s engine system, your AC will need refrigerant to work as a coolant. The good news is, you won’t need to add refrigerant to your AC unit as often as you would on your vehicle.

If you’re noticing a decrease in cold air coming from your AC unit or that it won’t turn on at all, it could be the result of a freon leak that’s not allowing your AC unit to function as it should.

A Broken Motor

If you notice that your AC was making some unusual sound before it stopped turning on, this may mean that the system had a malfunctioning motor. Again, you may have to do a capacitor test in order to determine if this is in fact, the cause of your broken AC unit.

The good news is, a motor can be fixed and can often be more affordable than replacing the AC unit as a whole.

Your Thermostat Needs Replacing

Many homeowners are unaware of the fact that the thermostat is an important piece of their overall AC system. This is due to the fact that a thermostat works as a control panel that communicates information to the AC unit.

Without the right information, your AC may result in simply staying in a default off mode. You want to check your thermostat to see if it is in fact broken, or if it simply needs new batteries.

When to Turn to Help

The first thing you want to do when your AC won’t turn on is to try to maintain calm and turn to a trusted professional.
