Hello.My name is XXXXX XXXXX I will do my best to help.Troubleshooting often requires meters and test equipment.Let's get started and see what we can do!
Your issue is most likely the bell controller on the end of the motor. However the only way to accurately troubleshoot to verify is with a special DC motor tester like this.You can purchase at any hvac supply house if you do not have one.
Hi Tim! My name isXXXXX sorry I do not have DC motor tester. Just a multi-meter. If the problem is in the bell housing that means replacing the motor anyway?
The furnace was installed in 2009. So the warranty is still in tact. I would tend to agree that it is in the controller. the motor never got warm or smelled funny, like a traditional motor failure. Once you have verified you have 120volts to the motor, the only thing left is the 16 pin DC connection from the motor to the board. Its about the only thing it can be right?
What would the DC tester have allowed me to do? or how would it have worked?
Thank you for your help!
