How To Deal With An Air Conditioner That Won't Turn OnShare
When your AC unit isn't working, there may be several causes. The problem can be as simple as a tripped breaker, or it may be something more serious. The good news is that you can usually troubleshoot the problem and get your AC up and running again in no time.
Here are some common causes of an air conditioner not turning on and how to deal with each of them. You can try to fix them yourself or seek professional help to get your unit up again.
Clogged Condensate Line
The condensate line runs from the bottom of your air conditioner out to the drain or sewer line. When it gets clogged, it can cause your unit to stop working properly and fail to even turn on.
If you have a clog in the pipe, water won't drain properly, and your air conditioner will shut off. To clear the blockage, turn off the power to the unit and use a snake or snake tool to remove the clog. If that doesn't fix the problem, you may need to use a replacement part.
Some units have filters inside the condensate line, which catch excess moisture in the system and prevent clogging. But if yours doesn't have these filters, you should clean out your pipes at least every few months. You can use a hose or garden hose attachment with a spray nozzle attached to it to clean the pipes.
A Faulty Circuit Breaker
An air conditioner not turning on might indicate a failed circuit breaker or fuse. Check these components first before going further. If they are tripped, reset them by flipping the lever off and then back to the on position.
If the circuit breaker or fuse does not trip, you need to check to see if there are any loose connections in the wiring. Look for a breakage anywhere in the line from the compressor to the thermostat. You can check all wires for loose connections or breaks with a voltage tester if you want to speed things up.
If you find any broken wires or loose connections, fix them immediately by replacing them with new ones of a similar size and gauge. Also, ensure all wires are connected tightly to avoid any loose connections later. This might cause another problem when you use your AC system again after a while.
A Problem With the Thermostat
Another common cause of an air conditioner not turning on is a faulty thermostat. If your thermostat stops working, it won't send the right signals to your AC unit. Therefore, your unit won't turn on when it should.
It's best to call a professional if you notice any signs of trouble with your thermostat so they can replace it for you to enjoy using your unit.
Also, your thermostat may be set too high or low for the current ambient temperature. Check the temperature settings before replacing parts or calling in a maintenance specialist.
