Blower Fan Motor Won't Shut off!- STEP by STEP Troubleshooting!

This is the Step by Step Troubleshooting of a 120 volt Furnace BLOWER MOTOR that will NOT SHUT OFF!. I go over the low voltage signal wires that tell the furnace to turn the blower fan on, I go over each step from where you should start to what is left at the end that would be the problem. We eliminate one thing at a time until we find the problem!
