I have a 9 year old Kitchenaid KUWS24RSBS00 wine fridge that has been edging up in base temperature a little at a time. The temp control dial is now set to its coldest setting but that only gets it down to about 59 degrees.
I removed the back from the fridge and cleaned everything thoroughly; there is still a rhythmic "ticking" sound (like the sound of tape stuck on a fan blade, but slower). I disconnected the compressor fan and the sound continued, so I'm not sure where the sound is originating (control board, maybe?). The compressor appears to be running and gets warm, but the output tube is not very cold.
Because Kitchenaid charges a king's ransom for their parts, I'm not anxious to just start replacing things until I have a better idea what is causing the issue. Thoughts?
