Contactor Trouble? A Guide to Electrical AC Repair

Sep 7, 2020

What exactly is a contactor? That’s a good question, and something we hope to answer in this blog post. However, just answering your miscellaneous electrical questions won’t get at the heart of what we’re trying to do. We want you to be ready for electrical malfunctions with a handy guide at your side.

Contactors are responsible for turning the air conditioner on and off. The “clicking” noise you hear when the system first starts up is the contactor signaling the system to either start or stop. While these electrical components are pretty reliable, they do break down from time to time and it’s up to us to repair them and get them back up and running.

Have more questions about the electrical components of your air conditioner? We thought you would! Keep reading for more information and don’t forget to call our helpful pros for AC repair in Albuquerque, NM.


Electrical Problems: Quick Fix or Agnonizing Replacement?

First off, depending on the electrical component that’s having trouble, you could see either a quick fix done by a professional, or something a little bit more complicated. For instance, contactor replacement isn’t that big of a deal when it’s spotted relatively early. When you’re dealing with a compressor failure, you’re in for a much more complicated decision to make.

Are you suffering from an electrical problem? Take a look below at some signs you might be dealing with electrical woes and then let’s see what we can do about it!

  • Constant Clicking. If you’re hearing multiple clicks in just a few minutes, then you’re likely dealing with a faulty set of contactors. These are relatively easy to replace, so you’re good to go as long as you contact a team of professionals.
  • System Shutting Down. This is a bit more complicated of a repair need. Shutting down air conditioners could very well be due to an electrical malfunction, but it’s hard to tell from a homeowner’s perspective. You’re better off getting a trained professional to take a look at it and diagnose the problem.
  • Buzzing. A malfunctioning air conditioner that’s suffering from electrical woes will make a buzzing noise. Buzzing might not be that bad of an issue, but it all depends on what is causing the buzzing noise.
  • System Incorrectly Starting Up. If you’re comfortable on a cozy night and your air conditioner has mistakenly started dumping cold air on you, you might be either dealing with a problematic thermostat or an electrical issue that’s causing it to run when it shouldn’t.
