It is time to change the cooling unit on the back of the refrigerator. The coach is a 2004, I replaced the cooling unit in 2014 and now in 2025.
I built this structure so I can slide the refrigerator out of it’s hole and then lay it down on the front to take the cooling unit off the back.
After I got the two pieces in of the support deck in the coach I screwed the top onto the base.
This is the old unit that needs to be replaced.
Got the old unit off, cleaned up, a Thermal mastic spread where the cooling tubes will contact the internal refrigerator box metal fins.
With Brian’s help I got the old unit off and the new unit on the back of the refrigerator box. It was a stuggle to get the cooling unit onto the plastic refrigerator box. The box was a little wider then the new unit, may be that over time the plastic box has spread some, it is 21 years old.
These are the internal fans I put in the refrigerator to blow air across the fins. I did this a couple of years ago. Also, have a fan down lower to push the cold air up from the bottom of the refrigerator.
