How to Check a Contactor

[@davidhand8337]

Thanks for the video. It helped me fix a problem with ants getting into my contactor.

Thanks for this important tip for aspiring HVAC . However I currently have a instructor who recommends not pushing in the "reset button" on contacts to do anything ! Now with that in mind , your presentation is still valuable , and I will try this next class when available in our labs.

Do you check with power to the unit? Or no power?

In the video, for a trained technician the power would be on. I would not advise without proper training. Although with all power off, indoor and outdoor unit…you could Ohm across the contactors points.
