My daughter has EWC Zone damper model MA-ND3. I removed the zone damper and I found that damper remained closed whether light is "green" or "red". Does this mean motor is no longer functioning?
Also I tried to remove the motor, I remove bolt on rear of the unit, but can't seem to remove. Is there another bolt somewhere?
MA-ND3 Damper is closed whether light is green or red.

Jim,
It could possibly be a bad motor. If you use the manual gear release button, can rotate the damper blades freely by hand? If yes, then the motor should be replaced. If No, then there is something obstructing the blades preventing the damper from rotating.
To remove the motor, there is a nut on the bottom edge of the motor that must be removed. Also, the U shaped bolt clamped to the damper shaft must be loosened. The motor should then slide straight off the damper.
