In some cases, a bad capacitor can cause the compressor to overheat and shut down. Second, improper voltage delivery to exterior unit components forces the system to work harder as it attempts to perform its job. Let us take a moment to decrypt the readings the meter is displaying now. When the AC is starting up, it needs 4-8 times more energy than it needs to keep running. What is the formula for potential energy is? Q: What happens if the wrong size run capacitor is used? If you check the wiring in your home to see if this is the reason, remember safety first. The capacitor helps to start the compressor and keep it running. A bad run capacitor deprives the motor of the full voltage it needs to operate correctly. It is evil now and is no longer serving its intended purpose in life. In our guide to AC capacitors, we discussed the differences between start and run capacitors. Motor run capacitor failure symptoms include warm air flowing from the vents inside the home, the air conditioner taking more time than usual to kick on or it turns off before it is programmed to, or there is a constant low hum emitting from the machine that isnt typical. A capacitor is one of the most crucial components of the electrical system in an air conditioning unit. The motor is running slowly: A slow-running electric motor can also be a sign of a failing run capacitor. If it runs longer than that, the compressor can overheat or its motor can burn out. 2.
