When it comes to air conditioner problems, most owners are worried about the day when their air won’t turn on. However, there very well may come a day when your air conditioner doesn’t turn off, even when it is perfectly cool outside and in your home. When this happens, it is still an indicator of a problem that you will need to address.
Check the Thermostat
The first thing you want to check when you have an system that won’t turn off is the thermostat settings. It could be that your thermostat is set far too low and your unit is struggling to reach that temperature.
Your thermostat also comes with fan settings. If the fan is set to “on” rather than “auto,” the fan will run constantly. This means your unit isn’t actually running, but rather the fan is simply circulating the air. This can be useful in keeping your home an even temperature, but it can be a drain on energy as well.
Check the Fan Limit Switch
Much like the fan setting on your thermostat, there is also a similar fan switch located near the blower wheel in your air conditioner. If your unit has been recently serviced or you cleaned it yourself, the switch may have gotten flipped accidentally and it can result in this issue.
Is Your Condenser Unit Dirty?
The condenser coils in your AC are charged with dispersing heat, but dirt covering those coils force it to work harder to perform that simple job. As such, your air conditioner needs to work harder, or rather, run longer in order to do the same job. If you cannot remember the last time you had your air conditioner maintained, then this is likely the problem.
