Subzero 550 Icemaker (Whirlpool Style)

10 posts in this topic

We have a Subzero with Whirlpool IM.

Just replaced the motor module...after reinstalling the IM in the freezer, the water valve cycles on and off properly, but water now spills past the IM and down the inside of the freezer. Problem seems to be that the water fill tube no longer overlaps the edge of the little plastic receptacle that projects up from the side/end of the ice maker assy. (Looks like this receptacle is supposed to form a chute to guide the water down into the tray.)

As best I can tell, I had the IM installed directly up against the panel it attaches to in the freezer. And nothing looks bent. Also, I gave the water tube a pretty good tug to see if I had jammed it back away from the IM, but it doesn't budge.

Is/was there a nipple or fitting of some kind that went onto the end of the water tube, that carried the water over into the receptacle (ie., that I lost in the process of taking the IM in and out of the freezer)? I looked thru all the photos for parts for "Subzero + icemaker" at the repairclinic site but didn't see anything like this.

I did remove and reinstall the plastic finger pieces and receptacle, so maybe I mis-re-assembled it somehow. But it looks like there's only one way to attach the receptacle to the tray...

As a quick, temporary fix I cut the neck off of a plastic water bottle and used it to sort of extend the end of the water fill tube. It leaks a little bit, and I want to fix it properly, but am at a loss for what I hosed up......

Any thoughts?

TIA,

Guy

The end of the fill tube must go into the little white box on the end of the IM. You must have it out of position slightly.

And that's all it takes is slightly because if the tube isn't seated right down in the cup, you'll make a beautiful frozen waterfill inside your freezer.

Sometimes, these are hard to get eyeballs on. Use a flashlight and inspection mirror if you need to.

Thanks for the response....

Agreed & understood, but those are the issues I'm looking at (and that have me stumped)

1. The end of the tube doesn't want to overhang into the little box receptacle (hence, the overflow);

2. If I stick my fingers up and wiggle the end of the tube where it tries to go in to the little box, and/or try to push the box back towards the end of the tube, there's no wiggle/give in either the tube or the box. Bottom line: There doesn't appear to be any way to adjust or extend or move either the end of the water tube or the top of the little box receptacle to bridge the gap;

3. When I (re)mount the IM to the panel it attaches to, I verified that the 3 IM mounting feet were up tight against the panel and the mounting screws were screwed in all the way.

But, it never leaked before, and it leaks now, so what am doing wrong?

But wait, there's more (a 2nd problem seems to have manifested):

How important is the thermal grease to the operation of the thermistor that senses the mold temp? About a month ago, the IM wasn't cycling on its own. I thought a busted thermistor might be the cause, so I took it out of the assy, placed it in a shallow cup of water (contacts up) with a (digital) thermometer probe, and checked continuity (open/close) vs temperature. I froze it solid (during which it was closed), then verified that it opened as it warmed up (by melting the ice with tap water). I made sure I didn't immerse the thermistor in water....

However, I didn't have any thermal grease (or adhesive - whatver its attached with), so I just reinserted it in the tray assy and made sure everything was screwed back together firmly, which is how I left it. I then installed a new motor module, saw the leak problem (see above), and am now faced with fixing the leak, as well as getting back to the (potential) thermistor/adhesive issue...

So, even though I have a slight water leak, the unit still isn't cycling on its own.

Do I need to go find some thermal adhesive/grease (and maybe a new thermistor) locally?

Gosh this is fun.

Thanks for your expertise....

The tube pulls out. It's probably stuck in there by frozen water. Twisty pully. Remove icemaker if you have to.

Yes, the use of exact terminology is an imperative pre-condition for clear comooooonications. :bart:

"twisty pully" works for me......

any idea on about how much of it should overhang into the little white box?

also, any comments on the thermistor installation (ie., do i need to re-grease it..(see end of previous post from me))

thanks again

I would be looking at the back of the frig to see how much of the tube assy is sticking out the rear of the box, you might even be able to  twistie pullie it out from there easier and re-inatall it by pushing it in, get your blow dryer to heat the area around the tube so you do not break it.  Do not have a clue about the lube question, will leave that to the Master.

That's thermal mastic, it improves the heat transfer between the thermistor and the ambient air. It's nice for more accurate temperature control but not crucial the run the refrigerator. You can buy a tube of thermal mastic from your local hardware store.
