I Have a Maytag side by side that is 3 1/2 years old. I had to replace the compressor recently. I keep hearing tapping noises coming from the ice maker. I checked to make sure the tubing didn't have a kink in it and replace rusty values under my sink, but the noise keeps happening. One repairman siad it could be air in the tube, but didn't want to work on it becasue the tubing was good. Any suggustions on how I could get rid of this noise. The ice maker makes ice okay.
