HVAC ECM Variable Speed Blower Motor Troubleshooting! Simple Testing!

In this HVACR Video, we go over the Troubleshooting of the ECM 3.0 Variable Speed Blower Motor and Testing with and without the TecMate Pro. I show you where the test voltage goes and how to check if the Fan Motor is good or bad. I have other variable speed motor diagnosis videos on determining if the actual motor is bad or the module on the side of the motor is bad.
