Testing ECM Variable Speed Fan Motor, Make Your Own Tester!
In this HVACR Troubleshooting Video, I go over how to make your own testing connector for ECM 2.3 Variable Speed Blower Motors. I show which wires in the plug send 24v and which ones are common and I show a bench test of the fan motor running using the Genteq TecMate Pro as well as the spare connector.
