Kitchen Aid Freestanding Ice Maker KUIS15NRTS0 is making ice slowly

13 posts in this topic

I've owned this icemaker for nearly five years and whenever this has happened in the past, I needed to clean the condenser coils.  Well, they're clean, but it is making ice at an extremely slow rate.  It might make enough for 5-6 large glasses of ice water in a day's time.  It used to make so much that it would be full almost all the time.  The water is pumping at what appears to be the normal rate and the condenser fan is working (at least I can feel the air at the base of the front of the ice maker when it kicks on).  Any idea about what could be happening?

What do the produced cubes look like?  Should be nice and square, maybe 1/4" at most.  Check your bin drain.  If it's a gravity drain make sure it's clear.  If you have the drain pump make sure it's working.  Easy way to check is to remove the bottom cap from the reservoir and allow the water to drain to bin.  Should be a significant amount of water leaving the reservoir.  If not you might not be getting enough water during fill.  Water should drain freely from bin.  If water backs up in bin, any ice produced in harvest will melt before you get to drop it in your root beer.  Same thing with insufficient water fill.  Not enough water result in a thin slab.  Once again ice melts before usage.  Try these simple checks first before moving on.

This machine should make and release a ice slab every 30 minutes.

What is the drop rate on your ice slab?

Is the cutter grid getting warm?

I haven't timed the ice slab frequency.  I'll check it.  But, the slabs are not consistent in thickness and are not as thick as they used to be.  The drain isn't the problem...it's gravity and it drains fine.  I'm wondering if the problem could be low refrigerant?  The pump seems to be pumping water just fine up to the top of the evaporator pan and it drains back to the reservoir just fine.  I haven't checked the cutter grid, but the ice it does make is getting cut, so I would think that means it's okay.  Yesterday I basically took everything out of the inside of it and cleaned everything up clean-as-new.  It didn't make any change at all.

Just an update on the ice maker.  I did check and it is ejecting ice about every thirty minutes, but the sheet is not consistent in thickness...the edges are very thin and it's wavy in general...seems to be thicker where the evaporator coils are located and much thinner away from them.  Also, the grid is warm, so it appears to be working correctly.  Could it be low of refrigerant?  If so, is it difficult to check (and add more, if necessary)?

The reservoir fills normally...just as it always has.  If the valve is malfunctioning, would it still do that?

Probably ok .  Read manual reg provided link to. If it is sealed system issue, probably time to call technician.

Well, it seems to be making ice normally again.  It's the strangest thing...

You should follow the "cleaning" directions and run a clean cycle to remove residue from the evaporator coil. This can make a difference in slab uniformity.

I did both of those things.  My first thought was the evaporator coil, but it had recently been cleaned.  I vacuumed it out again, for good measure.  I also followed the manual's instructions for removing some of the interior parts to clean them by hand and then ran a clean cycle using the proper cleaner.  Whatever caused the slow production was not corrected with those things.  But, it has corrected itself now.

Once again, my icemaker is making ice which is inconsistent in thickness and seems to only be making it toward the middle of the evaporator pan...not much or at all around the edges of the pan.  I've recently replaced the recirculation pump, as the original one died.  It appears to be circulating the water just fine now and a sheet of ice is ejected every half hour...just not too thick and, as I stated, the ice appears to only be making toward the center of the evaporator pan.  Could this mean that the machine needs refrigerant?  if so, how hard is it to add?  Can it be done from the front, or will I have to remove it from the cabinet in which it resides?


One additional comment...when I replaced the recirc pump, I did a thorough cleaning of the interior parts.  However, the slow production and inconsistent thickness/size of the ice was occurring prior to replacing the pump and cleaning.  It simply appears, to me, as if the evaporator pan isn't getting cold enough.  I would just call a repairman, but I live in a rural area and the last time I called someone to repair my refrigerator, they charged me an arm and a leg just to come out...before they even looked at it.
