If you have the Whirlpool residential refrigerator which I have on the 2015 Challenger 37ND, there is no requirement in the manual for winterizing the ice maker. The refrigerator manual has the procedures for placing the unit in storage which includes unplugging and leaving the doors open.
If you winterize the ice maker, as my selling dealer had done, it will take approximately 3 days to get all of the pink stuff out of the system when de-winterizing. That is because the pink stuff only turns to slush and the ice cube ejectors can not easily lift and drop slush.
My recommendation with the Whirlpool, read your refrigerator's manual and/or call Whirlpool.
