Air Conditioner Won't Turn On? How to Troubleshoot Your Broken AC
Look there are only a few reasons that your air conditioner won't turn on. So, let's take a look at some of them and get your AC up and running again. It's hot, right?
Step 1: Air Conditioner Won't Turn On - Check Your Thermostat
Make sure that your AC thermostat:
Has power.
Is set to COOL.
Has the temperature set at least 3-degrees below the current room temperature.
If your thermostat is battery powered, the batteries might need to be replaced. Otherwise, ensure that some rodent hasn't eaten through the wires! Make sure that it is in COOL mode, and that the temperature is set below the current one. If any of these are not true, then that's why your AC won't tun on!
Step 2: Air Conditioner Won't Turn On? Check Your AC Air Filter
We discussed how your AC works, so now let's imagine for a moment that something was keeping the air in your home from going over the coil that is supposed to be cooling the air. Wouldn't that coil get colder and colder without the air in your home heating it up? If it got too cold, eventually it would freeze up and block air flow in your home.
If you didn't follow me, that's ok. If your air filter is clogged, sometimes your AC won't turn on. Usually, it results in your air conditioner running, but not cooling your home, but it can also keep your AC from turning on at all if it's bad enough!
