Maytag Refrig winterizing

2012 DSDP 4086 with Maytag residential refrig. Winterized yesterday with the pink stuff. Got pink out of the water dispenser, but could not get anything thru the ice maker. Is getting pink thru the water dispenser adequate or something special for the icemaker.
thanks
Dave

Welcome to the forum and irv2,Dave.
Your service manual page # 25 explains what needs to be done.
This PIB is in additional to that.
Do not forget to remove water filter.
When I winterized my 1200 with ice maker I disconnected the feed hose up to ice maker, and put air through line with the wire arm in up position and drained line than used paper towels to remove any water in tray, never liked the pink stuff in ice maker.
You can get all this information by using the COM_NET2 LINK, in sticky above, and there are many PIB's and TIB's for your coach's in network.

Hi Dave,
This has concerned me as well. The Maytag and Newmar information does not really address getting the anti freeze through the ice making system. This year, I ran the generator for several hours while winterizing and turned the refrigerator and ice maker on, hoping to draw antifreeze into the ice maker supply line after winterizing the water line going to the refrigerator. After re reading the Maytag information, it might take longer than two hours for the ice maker to operate the water valve.

Mike

Thanks Mike and 007. Yes, the Newmar info is not helpful and is techinically for the wrong model of Maytag Refrig for the 2012 year. Correct model # is MFI2269VEM3. You can find manuals for this unit on the Maytag site, but no real help in winterizing. Mike, they do have a good pictorial parts list which can help you visualize the components. I spoke to Maytag tech people and learned the ice maker has a thermostat which will not along the water valve to ice maker to activate unless unit at proper operating temp. So trick is to have refrig running for +- 12 hours before attempting to winterize with RV antifreeze. Even then, what a pain to get antifreeze out of icemaker in spring since it won't freeze. However, if you don't do this, then you will likely have a +-12" water line to ice maker with only water subject to freezing, albeit not under pressure. Given the structure and valves of the water lines, I don't think you could even blow out the system adequately for freeze protection. So, either provide heat or winterize with antifreeze is best I can determine.

Thats why I never winterized just drained line up to it from water valve blow out water in line and than out of valve where line connects.
Used paper towels to get water out of tray.

maytag winterizing

Dave - I have the same questions. Last year I left the heat on but this year I'm doing something different. I'll leave the reefer on but turn off the ice maker. Then I'll apply low pressure air to the system and press the in-door water dispenser until just air comes out. By doing that the only water left should be between the valve and the ice maker. With air pressure still on the system I'll turn on the ice dispenser and wait for the ice to dispense (since I've left the reefer on, the ice should dispense almost immediately) and hopefully shortly thereafter when the valve opens to fill the ice maker the air will blow out the remaining water and I'll hear a momentary hissing sound---signifying that the water is out and air is being discharged.

I wish I had done your plan before I put RV antifreeze in my whole system. However, based on the parts pictures on the Maytag site, I think you will still have water in the reservoir. The reservior is not a tank, but a series of large lines made like interconneting "U"s. I think water will still be in the botom of the "U's after your blowout in the system. This may not be a problem as no pressure, but still water that will freeze. I think after your blowout procedure, I still would do the RV antifreeze thru the system and the door dispenser( not the Ice maker). It will be easy to purge the antfreeze from the system thru the door dispenser in the spring.

Dave - thanks for the info. Yes I plan to put antifreeze into the system after I blow it out with air---the either the Oasis factory rep or the Oasis manual specifically says that air alone will not suffice, that antifreeze must be put in the system to winterize it. And I don't trust air alone to protect the washer. I'm trying to find a way to qickly winterize the ice maker and avoid putting pink stuff in the ice maker. Joel

I thought I read somewhere that compressed air shouldn't be used on hydronic heat systems. Perhaps I didn't understand that they didn't recommend air alone. I live in a moderate climate and have always winterized my motorhome using air and no antifreeze except in the tanks and p-traps. I've ordered a new Ventana with a residential refrigerator and hadn't really thought through the process of how to winterize it so this have been an informative thread.
