One of the other posts had asked about winterizing the fridge. My friends at Martinsburg RV showed me a simple way to do it. First do your normal procedures and pump the RV antifreeze into the lines. When that's completed, to take care of the icemaker, do the following:
(1) Make sure the fridge is off
(2) Take the external vent cover for the fridge off outside your rig.
(3) look on the right hand side and you'll see a small electric pump (mine is red) with two wires coming from it. Disconnect those wires.
(4) Get an old electric cord from an appliance, trim off the ends and put the same type of electrical connector that you unplugged in step 3.
(5) Plug in your cord to the fridge, and then the other end into an electric outlet. On model 6400, there is one in the radio compartment right under the fridge vent.
(6) Go into the rig, make sure you have the water system pressurized with RV coolant (pump on), then turn on the fridge, and push the bar down on the icecube maker to turn it on. Make sure you have the empty ice cube tray underneath the icemaker.
(7) When you see the RV coolant coming out of the icemaker, shut off the fridge, go outside and unhook your plug in cable (from electric outlet and fridge) and replug in the original refrigerator electric lines to the red pump.
(
replace the outside vent cover and you're done.
This works like a charm. If there are easier ways to do this, I'm all ears. Hope this is helpful.
