I am hoping someone can advise me in respect of a problem with the above Maytag appliance, it's model number is GZ2626GEKB.

The air control damper has begun to make a terrible noise when it is closed. The damper is operating correctly to open/close and is keeping the fridge and freezer at the set temperatures. When the damper is open it is silent, however after closing it seems like the small motor is continuing to run and sounds like drilling a wall with a hammer drill. Not nice!!!
I think i simply need to obtain a new damper, but i wondered if there might be a fix. I understand this is a common problem with this type of appliance.

Thanks for reading this post.
