Things can get uncomfortable fast when your air conditioner won't turn on in Knoxville. Thankfully, R & M Climate Control Service Experts is here to help you stay cool, even when your AC isn't running properly. Here are eight potential reasons why your air conditioner won't turn on and how to fix them.
1) Check the Thermostat
The simplest explanation for your AC not turning on is a thermostat problem. Check to ensure 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 might also need to replace the batteries. If that doesn't fix the issue, the temperature sensor in the thermostat could be inaccurate. A thermostat that can't read the desired temperature could keep your air conditioner from turning on. Once you've discovered that the thermostat is broken, it's time to replace it. If you can't decide on a thermostat that's right for your residence, ask an Expert to help determine the best choice.
2) Check the Air Filter
Your air filter should be changed every 30-60 days at minimum. You should change them more often depending on the number of pets and people living in your home, and the local air pollution levels near 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 think of the last time you changed it, it's time to get 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 check 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 correcting this issue, you may have a serious problem and should get in touch with the Experts at R & M Climate Control 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 may have been flipped on accident. These switches are typically located near your furnace, in a closet, crawl space or attic. Once you find the shutoff switch, confirm it's in the "OFF" position. If so, just turn it back on. It's always a smart idea to label this switch to stop anyone from mistakenly turning it off.
5) Check the Outdoor Shutoff Switch
If you or someone else has recently serviced 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, you’ll need to flip it to allow your air conditioner to turn on.
6) Locate the AC's Reset Button
When your air conditioner won't turn on, it may simply need to be reset. Not all ACs have a reset button, so first find out if your unit does. If you can find the reset button, push it before trying to turn your AC on again. If you can't reach 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
Look over the air conditioner for any ice buildup either on or inside the unit. If you come across ice on your machine, you need to wait for it to defrost before trying to start the unit or you risk damaging the AC. Though there are various reasons you could see ice on your air conditioner, it's always smartest to call R & M Climate Control Service Experts for a consultation to keep further damage from occurring.
8) Ensure the Condensate Drain Isn't Clogged
If you don't find ice on the air conditioner, the condensate drain might be backed up. When clogged, your AC won't turn on as a safety precaution. To resolve the issue, unclog the drain line using suction from a wet/dry vac. Verify that you've removed the blockage by pouring a small amount of clear water and watching it flow out. For serious clogs, it might be best to call the Experts.
