I have a 4-5 year old Kenmore Elite Refrig w icemaker in bottom freezer. The icemaker makes constant creaking sound. When I open freezer it stops when the light comes on but if I push the light switch in...it starts the maker and squeaks again. It sounds like someone slowly opening and closing a creaky door. Putting the bail bar( I think thats what its called) up or down makes no change. Any suggestions?
