Kitchenaid under counter KUI15PHZS0 icemaker, resetting constantly, beeping

[nolazach]

Ice maker,  had a bad fill valve.  Was making tiny ice and reservoir wasn't filling.  Changed water valve,  ran diagnosis,  and reservoir filled right up. 

 

   Let it run normally,  it fills,  then when it's about to cycle the compressor on,  it beeps like it's being turned on again.   Then drains a bit,  then fills until full,  then beeps and starts over again.  

 

Very odd, was not doing this before the valve but would be odd to be unrelated.  

 

  The diagnostic process is easy.  You turn on and hold "clean and on" then max ice to advance.  Fill is step four.   Step six is compressor,  and it runs and cools. the hot valve works too.

Steps one through three  test thermistor and all test normal.  

It's a very odd issue to have.

Sorry wrong model number,  don't know how to edit post.

Sounds like it is stuck in clean cycle. 

Set it to ice maker mode.

Hope that helps

Turned off and on, cut power to the unit.  Restated.   Again it runs and resets,  it isn't running non stop as in clean.

Went and looked at it again.  Reset power.  Started.  Seemed ok.  

     Then thirty minutes later problem returned.  

Im going to change the control board I guess.   It's like no one has ever had this problem before.    When a problem is wonky and you can't find an answer,  replace the brains and go from there.

I'll renew my membership if anyone can answer this.    Please...

   What's going on????

You can't rely on diagnostic mode thermistor tests; those will only show if the thermistors are open or shorted, not if they're out of spec (which is how they usually fail). You'll want to check the thermistors' resistances against the measured compartment temperatures. The ice bin thermistor is a particularly common bad actor in these models.

UI measured the bin thermistor,  but in my experience that particular thermistor will cause the unit to not operate and the max ice or clean light to flash.  I didn't check the evap thermistor because it'll run on a timed cycle  when it's bad. 

    I should check the bin thermistor again. Maybe I missed something on the resistance to temp chart.  It was not opened or shorted though.  

     It's a pulling hair out thing because these are common units, but I've never heard of this issue.  

 

Do I have to reapply or can I renew as a former tech member?

There is a service pointer about the water level sensor here on the site 

[nolazach]

Can't see it,  though.  Can you tell me if it's related to the beeping??

Does this one have a condensate drain pump?
