Top Reason Your Air Conditioner Won’t Turn On

In Apache Junction, AZ, the performance of your air conditioner is vital to the comfort and even safety of you and your family. The Arizona summer heat rolls in strong, and your house can become an oven without good A/C. So if your air conditioner stops turning on or won’t come on when you flip the switch, you might have a problem.

Why won’t your AC turn on? An air conditioner is a complex system with failsafe and high power consumption. So, to determine why your AC isn’t turning on, you’ll want to investigate a little further or call the pros to give your AC a full inspection and tune-up. Superstition Cooling can help you diagnose and repair the issue with a quick tune-up or a more serious repair. Read on as we discuss some of the common reasons your air conditioner won’t turn on.

Most Common Reasons A/C Units Won’t Turn On

Air conditioners have a few reasons why one might not turn on automatically or when you turn it on manually. Let’s explore the most common reasons that can interrupt the power or trigger a failsafe.

Thermostat Issues

The first potential answer is that your thermostat doesn’t think the AC needs to run. If your temperature sensor isn’t working, it might not detect that your room is warm enough to run the AC. Alternatively, your thermostat may have stopped sending control signals to start the AC unit even when you set the manual settings.

Tripped Circuit Breaker or No Power to the Condenser Unit

If your AC or thermostat isn’t getting any power, it naturally will not come on. If the lights are on in your house, the most likely cause is a tripped circuit breaker on the same circuit as your AC. This is more likely in older homes and with older AC units. If your outdoor condenser isn’t getting power, this can also stop the whole system.

Blown a fuse in the AC Unit

Your AC also has an internal fuse to keep it from shorting out if there is a power fluctuation. If you have reset all your breakers and the thermostat is on, but the AC still won’t turn on, it might be an internally blown fuse that requires professional AC repair and replacement.

Clogged AC Air Filter or Drain

Your AC has a few fail-safes that rely on the proper flow of air and drain water through the system. If your air filter is clogged or the condensation drain has failed, your AC may stop working until the problem is fixed. You can call for an AC tune-up and maintenance visit to resolve any issues you can’t identify.

Air Conditioner Motor Failure

Your AC can cool, but it can’t move cold air without the blower fan. If your fan motor fails, then your system will stop running entirely. Professional AC repair services can diagnose and repair your fan motor in no time.

Refrigerant Leak

A refrigerant leak is a serious issue, especially if you have an older unit. If you detect any problem with your refrigerant, including icing on the lines from your compressor, call for AC repairs immediately. Your coolant will be replaced with a much safer modern formula, and the source of the leak will be sealed.
