damper motor spring return
damper motor spring return
i have a three zone system with MA-ESR damper motors. Is it possible for the opening spring to fail. i have been constantly climbing in to the attic to just take the cover off of the motor and tap the top of it and the damper will open. Also can you replace the motor without having to open the duct work i have a replacement motor any help would be appreciated.

Re: damper motor spring return
Yes, since it is a electromechanical device it is possible for one or more of the parts to fail.
You can replace that motor without having to remove the damper from the duct work.
I will attach a document that should help you.

How can I determine if an MA-ESR controller is working properly other than by testing the air flow?

Re: damper motor spring return
Unfortunately there are no LED indicators that show Open or Closed position on the MA-ESR motor.
The best way to tell if the motor is working properly without actually taking the damper out of the duct-work would be to test for airflow.
Do you have a voltmeter you can use to troubleshoot with?
If so you would want to set one of your thermostats to the fan on position. It would be best to choose the one associated with the damper in question.
Once the fan is running, check for voltage at the motor itself between the "M" and "M" terminals.
Then go to the zone with the faulty damper and feel if the air is coming out of the register.
If you did have 24V at the motor - remove a wire from one of the "M" terminals and check for airflow again.
A significant increase or decrease of airflow will tell you that your damper is functioning.
If you did not have 24V at the motor - apply 24v to those terminals.
Check for airflow again.
Again, a significant increase or decrease in airflow will tell you that the damper is functioning properly.
