Ice ball on ice maker

On my Norcold 1200 fridge, the icemaker has begun to malfunction. A large mass of ice develops on the left side, the opposite side from where the water inlet tube is located. It grows each day and we eventually raise the ice bail and stop production. I read in this forum that the water feed is timed for a set duration. If this is so, if you have high water pressure you could get excess water to overflow the ice tray. Perhaps this is my problem? Is the solution as simple as keeping the pressure regulator constantly set at some lower value, say 40 psig max? I also have the flaking of the surface coating of the ice trays. Is this just an annoyance or is it a major concern? The unit is a 2005 model. Any help would be appreciated.

Pressure shoudl be set to 45-50 PSI max, no more.

I have been in parks where the pressure hit over 100 PSI (in fact I saw the needle swing past 120PSI) now that kind of pressure can blow up filters, hoses and damage the seal on the flush valve on your toilet.

So please, regulate.

Now.. to adjust the time on the water valve

Pull the front cover off the ice maker (it can work w/o the cover by the way) use your right hand and reach around the front coverand pull.. No screws, No fasteners just some push pins that pull out

You will see the screw and there will be instructions stamped in the metal plate (it is above the big gear wheel as I recall)

NOTE: to manually cycle the Ice Maker to winterize... Turn big wheel in direction of arrow (Thought I'd point that out while you have the cover off)
Home is where I park it!

wa8yxm is right about needing a regulator. I have seen water pressure that pegged my 100 psi pressure gauge.

The problem with the Norcold 1200 refrigerator is the ice maker is installed sideways - at least it is in ours. You can't get the cover off without removing the whole icemaker, so hopefully, regulating the pressure will fix the problem.

We had an icemaker in our old stick house that started to loose the coating from the ice molds. It seems like it's a Teflon coating to help keep the cubes from sticking. Ours eventually got so bad we had to replace it. The good news is the icemaker in the Norcold is similar to what is used in many household refrigerators. You can find replacements in appliance parts stores and places like Lowe's. Just make sure you match the plug that plugs into the wall of the freezer.
