Furnace/AC How to Troubleshoot The Control Board

Furnace or AC control board troubleshooting. Do you suspect that your furnace/AC control board is bad? Is your air conditioner or furnace not turning on or perhaps the the indoor fan is not coming on? In this video I show you hot to troubleshoot or diagnose your control board in the furnace or air handler to see if the board is defective or not. I just want to say that there are many different kind of control boards and some will be wired differently so do not take my example in the video as law. Some furnaces have a slightly different set up. Also, make sure you do the repairs safely. Be cautious of electricity. Good luck!
