How To Fix The Power Supply Of Your Condensing Unit


Is your air conditioner acting up? Even just having an HVAC specialist come to your property to look at your ailing AC system can cost upwards of $100. However, if you have a ground condenser unit, there's a good chance that you can fix many of the most common problems on your own. If your AC unit is mounted on your roof, especially if it is a slanted roof, you should probably let the professionals service it.

If your fan is not starting up, your air-conditioner will have no way to circulate the air into your own.

Test the Power Supply

The first thing to do is to check the fuse and breaker panel. Switch the breaker on and off and then retest your air conditioner. If this doesn't solve the problem, you need to locate the capacitor to test it. But, don't try and work on the capacitor after the air-conditioner has been running because it can be extremely hot. Wait a couple hours for the capacitor to cool off and then begin work. First, remove the excess panel along the backside of the condensing unit. This panel should be clearly marked it easy to locate.

If there is no positive read on the input wires, the problem might not have anything to do with the capacitor. However, if the input wires are live and the output wires not, the problem almost certainly has to do with the capacitor. In this case, you will want to change the capacitor. Before you do, go turn the power to the AC unit back off at the breaker panel. For a guaranteed match, you should take you actual capacitor into the store when you go to buy the replacement.

Installing the new capacitor is easy if you follow the included directions. It usually just requires a couple of handheld screwdrivers. When the new capacitor is installed and the power is turned back on, you can test your system. Hopefully, this simple repair will have fixed your condensing unit.
