What is an AC contactor and what does it do?
An AC contactor is an electromagnetic device that is used to control an electric circuit. The contactor is activated by a control signal, which can be generated by a switch, timer, relay, or another device. When the contactor is activated, it completes the circuit and allows current to flow. This can then be used to power electrical devices or activate other control devices. AC contactors are used in a wide range of applications, including air conditioners, refrigerators, and vending machines. They are also used in industrial settings to control motors, lights, and other equipment.
Signs that your AC Contactor may be bad
One of the most important components of your AC unit is the contactor. This component is responsible for supplying power to the unit, and if it fails, the unit will not be able to operate. There are a few signs that you can look for that may indicate that your contractor is beginning to fail. First, listen for a clicking noise when you turn on your AC unit. This noise may indicate that the contacts inside the contactor are not making a good connection. Second, check the unit for signs of burning or charring. This may be an indication that the contactor is overloading the circuit. Finally, take a look at your energy bills. If you notice a sudden increase in your energy usage, it may be due to a failing contractor. If you notice any of these signs, it’s important to call a professional AC repair technician for help.
How to replace an AC Contactor
Replacing an AC contactor is a relatively simple task that can be completed in a few minutes. First, locate the AC contactor. It will be located near the air conditioning unit, typically inside a metal box. Once you have found the contactor, remove the cover to expose the terminals. Then, using a screwdriver, disconnect the wires from the old contactor and connect them to the new one. Finally, replace the cover and screw it into place. That’s all there is to it! With just a few simple steps, you can easily replace an AC contactor.
