If your air conditioner isn't working, you may be getting a little hot under the collar. A hot home is not very relaxing, and if you're in the middle of a heat wave, it can be even worse for you and your family. If your air conditioner isn't working at all, there are things you can do to troubleshoot the problem. Read on for troubleshooting tips to get your air conditioner working again.
Check For Power
If your air conditioner is not turning on, you may have an issue with a blown fuse or the power may have gotten unplugged on your air conditioner. Check for power on the system itself first, then go to your breaker box and look for a blown fuse. If the fuse was blown, turn the fuse back on and test your system. If the fuse continues to blow, you may have an issue with a short in your system. If this is the case, you should hire an electrician for help because your breaker may need to be updated. If neither of these was the case, you'll need to investigate further.
Check The Thermostat Settings
If your thermostat is not set to cool, it isn't going to turn on your air conditioner. Make sure the setting is set to cool. Change the temperature to see if this turns on the system. Lower the temperature and listen for the system to turn on. Also, take the cover off of the front of the thermostat and inspect the wiring. You need to be sure the wiring is in place securely. If you notice loose wires, you can secure them in place yourself or hire a professional air conditioning repair company to do this work for you. Also, check that the batteries inside are working. Change them out to be sure if your thermostat has batteries. If this didn't help turn on your system, continue to troubleshoot.
If your system is still not working, it's time to call an air conditioner repairman for help to make the repair. Your air conditioner may need more work than you may be able to handle. Other reasons why your system may not be turning on could be due to a blown capacitor, a broken thermostat, or the fan outside turning on and off, leading to overheating. No matter the reason, if you aren't sure how to make the repair yourself, it's time to call an air conditioning repairman for help.
