How to repair the Ice Maker in your RV Fridge.

My Retro-Winnie developed a water leak in the Freezer

Well, here I am, starting on my next fix or possible upgrade to my RETRO-WINNIE.

While we were camping in lynchburg last month, a little problem developed after about three days in our campsite.

We started getting Ice buildup on the bottom of the freezer.

Our Fridge is a NorCold model and it is original equipment. The fridge and freezer has worked great when we tested it out before our shakedown trip, but we never did take the time to use the Ice Maker.

Now, back to my problem;

A Water Leak in the Freezer

This one was new to me. Our Ice Maker worked great for several days and then, one morning, I opened the door and saw that several of our frozen food packages had a thick coating of ice on them.

I quickly pulled them out of the freezer, knocked the ice off of them and placed them back into the freezer. I took a deep breath and then I told my wife that I thought we had a little problem developing.

By that evening, I saw that I was right. We never saw actual water, leaking in the freezer, but we did have an obvious water leak that I finally discovered was dripping from the bottom of the control section of the Ice Maker.

After cleaning out the freezer, again, I jumped onto my PC, and downloaded a set of old NorCold Ice Maker service and installation manuals. And, after going through them, I realized that I had at least one of several potential problems.

One, the Water Valve assembly in the Ice Maker was mis-functioning, or;

Two, the Input Water Hose was leaking (possible old and cracked?), or;

Three, The leak was inside the Ice Maker assembly and the whole thing needed replacement.

So, being in a campsite, far away from home, I decided to "jackleg" the problem, at least temporarily until I got home.

Because the water leak was at the very edge of the control section of the Ice Maker, I modified a plastic storage container and removed the lip along one edge. I then place the plastic container directly against the edge of the Ice Maker where the leak was coming from.

My idea was to just catch the freezing water in the container and continue to use the ice Maker for the next couple of weeks that we were camping. I also placed a bag of frozen Peas against the plastic container to keep it wedged tightly against the side of the Ice Maker.

It worked great! Each morning, I would open the Freezer door, break off the 1/2-inch diameter shaft of ice that had developed down into the container, and then I removed all of the ice in the container.

Then I would replace the container against the Ice Maker, (with the bag of Peas, of course) and; Voila! We continued to get Ice for the remainder of our camping stay.

When my icemaker in my old Winnebago finally went bad, I purchased this replacement unit, and it was easy to change and worked great.


The Search for a Replacement Ice Maker

So, I avoided having an "Ice buildup Problem' because of my little temporary fix.

But, once I got home, I had to come up wit a "real" fix.

The first thing I did was remove the cover again and take a picture of the label on the Ice Maker. The label was under the cover at the end. And, I took another picture of the label on the NorCold Fridge itself, just for good measure.

Once we had put our Retro_Winnie in its storage site, I got online again and went to the Norcold site to find the proper replacement part. And Yes, by this time, had already decided that I would not "just fix" the Ice Maker.

i have found that although you might want to replace a cheap part inside a device on your RV, to save a couple of bucks, it is usually best to replace the whole assembly. There are several reasons for this;

1-the dis-assembly and re-assembly of old devices can end up with your generating even more broken parts,

2-if the device is cheap (I found I could get a new one for $80-$150 on the web) and it's usually not worth your time to repair such a cheap device, and

3-The new unit will have ALL NEW PARTS in it, and this means you will most probably have a number of trouble-free years before the new device gives you any problems.

A Common Device, the Ice Maker

After the first couple of hours of research, I made a discovery. This design of Ice Maker has been the most common device used for at least 15-years in nearly every manufacturers Fridge in the USA.

But, even though they are common, each manufacturer has purchased one "just for them" and labeled with a different model number, of their own. A replacement part money-making strategy, I guess.

NorCold didn't even have an Ice Maker model number for my model of Fridge (it was too old) so i lost out there.

Anyway, I fell back to the label on the existing Ice Maker. Well, no one, not even eBay has this any information on my specific model number.

A little confused and frustrated by this time, I stared at my picture on the label and then I saw it. The one in my 2001 NorCold fridge was manufactured in 2010 for Whirlpool.

So, I assumed from this that the Ice Maker had already been replaced by the previous owner.

As my search went on, I did finally settle in on two very common model numbers that popped up on numerous sites.

These magic numbers are;

621226, and


I even found one site a forum site for RV owners, that stated that these numbers are common to nearly all NorCold refrigerators used in RVs for the past couple of decades at least.

So, Now What?

NorCold Ice Maker Water Valve

Norcold 618253 Ice Maker Water Valve
Norcold 618253 Ice Maker Water Valve

There was a slow water leak in the valve connector of my NorCold fridge in my old fifth-wheel camper, and I purchased this replacement. It was easy to change out and worked great.


Off to the Sears store

Yeah, that's right, my best solution has turned out to be; either buy on eBay, at some kind of high pricing, or I can remove my Ic Maker, and go over to the Sears parts store, not far away, and compare my unit to what they have on sale.

You see, their list what looks like an identical Ice Maker, but it has a totally different model number.

Not in Stock at Sears

That's right, after a drive to the nearest Sears Parts store, it turns out that they did not have the appropriate Ice Maker in inventory. The online site for Sears said they did, but the guy (a short, frowning, indifferent clerk) denied one existed.

Frustrated, I had to regroup.

After returning home, I got back online and after a half an hour of using different search criteria, up popped an "appliance part sales site" that sold Ice Maker replacement units. But the great thing was that they said if I sent them my units part number, they would cross reference it for me to a list of available units.

They came back with yet another number that is (they say) a direct replacement for my Ice Maker.

By now, I have become tired of this problem and the price was right, so I ordered the replacement unit.

And, now I am waiting for the delivery.

I will add a Part-2 Article on my Ice Maker adventure, once I receive the new part.

RV TIPs on Ice Makers

Here are some tips for other RV owners that they may not already know:

110-VAC Operation Only

The Ice Maker in all of these older RVs runs on 110-VAC ONLY. That's right, even though your Fridge and its Freezer will run equally well on 110-VAC or Propane gas. the Ice Maker is strictly a 110VAC device.

So, unless you are running your generator, I recommend that when you are not hooked up to campsite power, because your Ice Maker will not operate without 110VAC, you should flip the Ice Maker lever to the OFF position.

ice Maker Lever Positions

And BTW, the standard is OFF with the lever in the UP or lifted position. DOWN is ON, and UP is OFF.

Anyway, it is highly recommended that you lift that lever on the Ice Maker while traveling. For one reason, a rough road will spill water all over the freezer.

      I hope someday to be coming back to this article to fix my own RV ice maker because that will mean I have reached my goal of going for a walk about. :)

      MsDora- Nice to hear from you again. As an avid Camper for most of my life, one of the things I do know is that the majority of campers are of the occasional variety. And the of these only a small percentage are into doing their own repairs.

      And, an even smaller percentage of these are knowledgeable of the unique problems you can have with a Camper.

      So, I hope my step by step procedures and problem explanations can help them when they do run into a problem.

      Thanks again,

      JamaGenee- Having a great day, I hope!

      As to the Ice Maker, actually it is an accessory that can be added to a freezer for those who want an automatic source of ice.

      It seems that for years, decades even, for your Rv or home Fridge you could order it with or without an ice maker. And, I have found that "back then" many of the ice-makers used were a standard design configuration used by the majority of the Fridge manufacturers.

      Today, though, the top end Fridge manufacturers have gone a little wild and started designing their own Ice Makers.

      For instance, recently, i upgraded my home fridge to a very nice stainless "French door" style unit.

      And the Ice Maker is a complex, noisy, crappy built-in unit.

      We hate it, considering the cost of the Fridge, but what are you going to do but give them a bad review?

      Anyway. thanks for the question,

      Don, as you know, I don't own an RV but I do enjoy your fix-it or workaraound hubs in case I ever do! One thing though. Was the ice maker an integral part of keeping frozen food frozen, or merely a nice "luxury" feature to keep from having to buy bagged ice for your ice tea or lemonade at or near the campground?

      Upped and shared! ;D
