I am hearing a loud chattering noise occasionally that is coming from the upper left corner of the fresh food side. At first it sounded to be a fan blade hitting on something but I looked behind the cover and found there is only a solenoid in there so the solenoid must be chattering. Reading some of the topics here it appears it may be related to the icemaker. The icemaker does appear to be working OK.

I'm hoping this might be a common failure problem that somebody will recognize and be able point me in the right direction.

Thank you in advance for any help.
