What To Do When Your Air Conditioner Won't Turn On


If you have found yourself in the middle of a scorching hot day and your air conditioner won't turn on, don't panic. There are a few troubleshooting things you can do to figure out why it won't turn on and possibly even do the repairs yourself.

Check That The Thermostat Is Set Properly

There are a few different causes of an air conditioner not turning on. The first thing you can check is the thermostat. This is often the reason an air conditioner won't work properly. It is possible that the settings accidentally got adjusted. If you have one that you program to a certain temperature, verify that it is set to the right temperature. Try turning it down a few degrees and see if the air conditioner comes on. It is possible that it is set too low. If you believe the thermostat is defective, call an HVAC professional to have it repaired.

Find The Circuit Breaker And Fuse

You may also be having trouble getting enough power to the thermostat and air conditioning system. Make sure the unit is plugged in and that all the switches around the air conditioner are turned on. Check the wires and cables to the main unit to be sure they are all in good condition. Next, find your home's circuit breaker panel and be sure the circuit breaker for the air conditioner is in the on position. It might have blown if the lever is pointing down. Point it back up to reset it. If that doesn't work, go to the electrical panel and check to see if the fuse has blown. If so, it will need to be replaced.

Inspect The Condensate Overflow Tray

When you have made sure the thermostat is working and that the air conditioner is getting a sufficient amount of power, the next thing to check is the condensate overflow tray. This is used to collect excessive water. Not all units have them, but if yours does, it will be located in the remote air handler and is an alternative to a condensate drain. It is possible that the sensor switch for the tray is turned off.

Find The Blower Door

The last thing you can do is check the blower door. This is the door that is in front of the air handler. It must be closed in order for your air conditioner to turn on and start sending cool air through your home. If it is opened accidentally, close it and try your air conditioning unit again.
