Residential Refrigerator Winterization

[Bill Heffernan]

We have a JennAir residential refrigerator in our rig. What are recommended methods to winterize the water dispenser and ice maker. I've used the pink stuff to winterize everything else. I've read discussions about using air, but have not been able to figure out how to piece together a device to connect my compressor to the water line. Thoughts? Recommendations? Thanks!

Bill,
I may be mistaken but I think you need to apply air to the ice maker end of the water line since there is valve at the ice maker that only opens when the ice maker demands water. I would disconnect the line at the rear of the reefer and at the pump side of the filter at the water pump and blow it out toward the water pump.  If the line on the back of the reefer doesn't have an bends in it, it will probably drain by itself once you've disconnected it. Alternately if you can get to the back of the ice maker and disconnect the line there and apply air, you will be sure the line is empty. Check the ice maker but it shouldn't have any water in it if it has cycled. If there is any, you can soak it up with a microfiber cloth. To apply air, the tip of an air blow gun should work. They are available at Lowes, HD, Ace, etc.  https://www.homedepot.com/p/Husky-Blow-Gun-Kit-7-Piece-18249HOM/205331812
