Eight Reasons Why Your AC Won’t Turn On-And What to Do

Things can get warm fast when your air conditioner won’t turn on in Winnipeg. Thankfully, Winnipeg Supply Service Experts is here to help you remain cool, even when your AC isn’t functioning properly. Here are eight potential reasons why your air conditioner won’t turn on and how to fix them.

1) Check the Thermostat

The easiest explanation for your AC not turning on is a thermostat issue. Double check your thermostat is on, set to “cool,” and that the temperature is set to a few degrees lower than the normal ambient temperature of your home. You may also need to replace the batteries. If that doesn’t take care of the issue, the temperature sensor in the thermostat may be inaccurate. A thermostat that can’t read the set temperature could stop your air conditioner from turning on. Once you’ve discovered that the thermostat is malfunctioning, it’s time to replace it. If you can’t decide on a thermostat that’s right for your residence, consult with an Expert to help determine the best choice.

2) Check the Air Filter

Your air filter should be cleaned or replaced every 30-60 days at minimum. You should change them more regularly depending on the number of pets and people living in your home, and the local air pollution levels close to your residence. A dirty air filter can restrict airflow, causing your air conditioner to freeze and not turn on.

If your air filter appears dirty or you can’t remember the last time you changed it, it’s time to replace it with a new one. If your AC was frozen, wait for it to thaw after changing the filter before turning it back on.

3) Check the Circuit Breaker

Open the electrical panel inside your home and attempt to see if the circuit breaker connected to your air conditioner is tripped. You can identify if the breaker is tripped if the switch has flipped to the “OFF” position. To resolve this issue, simply flip the breaker so that it’s in the “ON” position.

If your AC continues to trip the breaker after fixing this issue, you may have a serious problem and should get in touch with the Experts at Winnipeg Supply Service Experts to stop it from damaging your home or air conditioner.

4) Check the Indoor Shutoff Switch

Often mistaken for a light switch, if your AC won’t turn on, the indoor shutoff switch could have been flipped on accident. These switches are typically placed near your furnace, in a closet, crawl space or attic. Once you locate the shutoff switch, check to see if it’s in the “OFF” position. If so, you’ll need to turn it back on. It’s always a smart idea to label this switch to stop anyone from mistakenly shifting it off.

5) Check the Outdoor Shutoff Switch

If you or someone else has recently worked on your air conditioner, they may have turned off the external shutoff switch as a safety precaution. First, find the external shutoff switch, which should be near your AC unit. If the switch is in the “OFF” position, simply flip it to allow your air conditioner to turn on.

6) Identify the AC’s Reset Button

When your air conditioner won’t turn on, it might simply need to be reset. Not all ACs have a reset button, so first determine if your unit does. If you can find the reset button, move it before going to turn your AC on again. If you can’t find the reset button, manually reset your air conditioner by turning your thermostat off for five to 10 minutes before turning it back on again.

7) Inspect the AC for Ice Buildup

Check the air conditioner for any icy buildup either on or inside the unit. If you come across ice on your machine, you need to wait for it to thaw before attempting to start the unit or you risk damaging the AC. Though there are various reasons you might see ice on your air conditioner, it’s always smartest to call Winnipeg Supply Service Experts for a consultation to keep further damage from occurring.

8) Ensure the Condensate Drain Isn’t Clogged

If you don’t come across ice on the air conditioner, the condensate drain may be backed up. When clogged, your AC won’t turn on as a safety precaution. To resolve the issue, unclog the drain line with suction from a wet/dry vac. Check that you’ve fixed the blockage by pouring a small amount of clear water and watching it flow out. For severe clogs, it could be best to call the Experts.
