Raritan Icer-Ette

Raritan, u-line, mom-pop, They all use a tray that is heated just before dumping.
We hate them all when they fail, leak, dump water on our decks. When they work well, sometimes for many years, we praise the same units.

If it freezes water, replace the whole ice maker assembly. Replacing the switches and goofing around other parts is a waste of time.
If it does not freeze water, Don't f... fool with it, get a new unit.

Also check this lead and search for many others if you like abuse.

ice maker

The icer-rette unlike icemakers in home frigs, has a freon charged cold plate mounted to the bottom of the mold. This allows for faster cooling of the mold and faster ice making than if just cooled by the inside temp. If you remove the compression plate which holds the cold plate firmly against the mold while the system is charged, then as Capt J stated the cold plate's coil will expand and will be ruined.

I'm fixing mine as we speak…..Raritan says if you leave unit ON while you replace the Harvestor or module, no recharging required as the freon will remain within the coils.

I managed to get it fixed…

Now ice drops into Tray, but the ice starts to melt on bottom of tray….at the end of it all, I end up with a almost a solid tray of ice?

Perplexed!

Not sure….Fridge is nice and cold….so can't figure out what is going on?

I am curious also, did you replace the ice mold by running the compressor to keep the freon filled cold plate from expanding?

Did that work for you?

Yeah….no problem there

here are some suggestions to check in regards to your current problem.

Check these:

1. water overflowing into the storage bin then freezing.

The water tube that directs the water into the tray may be slightly out of place allowing water to overflow.

The solenoid valve that allows the water flow is not closing completely, allowing the ice tray to overflow.

There is an adjustment on the front of the maker (under the cover) that controls the amount of water to enter to control the size of the cube. Try to back off this adjustment to limit the water. see or download the manual for the screw to adjust.

2. ice melting and refreezing.


Look for gaps or tears in the door seals

or door not completely closing.

All I can think of right now.

Door Seals are good…
No water leakage….

Not sure where this adjustment screw is…but don't think that is the problem, as soon as I heard the cubes fall down, i opened door and checked what I saw…all looked good, no water and cubes looked normal.

Must be melting a touch and then refreezing, but can't figure out why?

I do agree, if it was from overflowing, you should see water in the ice bin or at least some water dripping down, immediately after a recycling cycle finishes and ice drops into the bin.

Just put the picture with the screw here and the instructions for others that might be following this thread now or in future.




Turning the set screw clockwise decreases the water fill. 1/2 turn = approx 20cc of water. No more than one full turn in either direction or damage to the module could occur.

ok - I saw that screw as I was installing trying to figure out what it does. It doesn't seem to be attached to anything? I thought it was probably there to use as an insert to adjust something?
Who know…..Its making cubes and no water when ice comes out….Will keep trying to see what I can find?

So…..Seems the problem as far as I configure now after playing with it some more is quite simple.

Seems the bottom of the freezer cabinet is slightly indented so the Ice cube tray does not sit flat on the freezer. Thus the first batch of cubes melts slightly until the whole interior cools all the way down and first batch of cubes cools the tray down to freezing from inside the tray, rather than as should be be from the bottom exterior.

I will try to turn the unit on a couple of hours first with the arm up so as no cubes comes in until I confirm a steady cold temp. Then I will lower the arm and see if the cubes keep from melting and the batch can maintain solid cubes thereafter.

Geez….Feel like I am back in High school doing a Science experiment…..
