Показать описание
This is the Quick and Easy Diagnosis of Variable Speed Blower Fan Motors. I cover Genteq ECM Fan Motors 2.0, 2.3, 2.5, and 3.0. You need to make sure that you are correct in your Troubleshooting because these are not generic motors. Each motor is programmed by the HVAC Equipment Manufacturer for a specific model Air Handler or Gas Furnace. The homeowner or Business Owner will be Without Heat or AC until this is resolved and you likely will not have the correct motor in the Service Truck. Make sure it is not a loose communication wire as I have found many times and make the Correct Diagnosis! How to Troubleshoot a Variable Speed Blower Fan Motor Easily and Quickly! Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.

Thank you very much for you information, i haven't checked my tec inspect with another motor, i just bought it especially to test this specific motor, but I'll do it for sure, thanks !!

You can make one of these using an old low voltage variable speed wiring harness... you just leave the plug end and follow the schematic to see which are going back to r and c... handy tool none the less

Correct me if I'm wrong... If the blower doesn't start when you flip the switch it means 1 of 2 things: bad motor or bad module (not necessarily the motor, as stated in the video).

To determine which of the two it is you have to remove the control module and ohm test the motor. If the motor is good it has to be the module.

Much cheaper to replace the module than to replace both motor and module.

I have a Lennox 90% Flash e 201 which is not connecting with blower
Put my motor tester on made sure I had my constant 115 and blower did not move I change the blower motor and after a day I'm getting the same code again if you reset the furnace it'll run for a cycle or two then start flashing code again
