Winterizing a residential refrigerator
Stuck in the northland for a few weeks and forced to winterize my Georgetown. I am pretty good at this stuff and have read almost everything I can find on the forum and otherplaces about the icemaker. I am somewhat perplexed. OK, I need to get all of the water out of the reefer and cycle the icemaker. RV antifreeze will taint the polyethylene tubing in the frig. I will use compressed air to force out all of the water in the reefer, including forcing the icemaker to cycle to clear the water in the solenoid valve that feeds the icemaker. But....
I can't figure out why I should disconnect the 1/4" poly line to do this when I am going to put 30# of compressed air in the entire RV to blow out all of the other lines. My plan is to use a blow out fitting to drain all of the water from all of the fixtures AND THEN get the water out of the cold water tap on the reefer. Then, when that is done, I will open the icemaker and force it to cycle enough to get the remaining water out of it as well.
Might put RV antifreeze in the unit to all of the faucets and shower just to be sure and perhaps plan on turning off the 1/4 valve that feeds the frig at that point to avoid putting any in the reefer.
