    • Appliantology Live Dojo, Saturday, 4/27/2024 @10 AM ET
      27 April 2024 02:00 PM Until 03:00 PM
      5  
      All Appliantology tech members are invited to join in this workshop on all things Appliantological. 
      We have a special session planned for this one. Instead of the usual Show 'n Tell on a technical topic, we're going to post tech sheets in the comments to this Calendar Event (scroll down to see what's posted so far) and ask specific questions that can only be answered by reading the tech sheet. If you at least try to answer the questions beforehand, you'll get a lot more out of it. The tech sheet and the questions are posted in the comments section below.
      Your mission, if you should choose to accept it, is to check out the questions for each one and try to answer them ahead of time. Then come to the Dojo to see how well you did! 
      Who: This workshop is only available to tech members at Appliantology.
      When: Saturday, April 27 @10:00 AM Eastern Time.
      Where: Online via Zoom
      How:
      Click here to go to the forum topic with the registration link. If you're interested, register now. Arrive a couple minutes early to make sure your connection is working. Set a reminder for yourself for this workshop so you don’t miss it.  And check out past workshops here: https://appliantology.org/announcement/33-webinar-recordings-index-page/

French door bottom mount unit runs down to -20F in freezer even with the setting at warmest temp. Coil frosts up but bimetal and heater check out ok. I suspect board but wonder if the thermistor for freezer could be bad and not giving the board good readings. And frosted coil is simply due to unit not shutting off on temp. The  customer reports fresh food doesn’t lose temp so there must be some defrost action happening.

Sounds like your Main control (Jazz Board) has a stuck relay which is sending power to the compressor constantly. You can test this by attempting to force a defrost.

-20 is about the limit of how cold these can get with the compressor running 24/7. Let us know what you find

You nailed it. I had checked the thermistors after posting the question but before I got all this beatific apliantological wisdom. So I was mostly sure a board was in order. Now? Well I’m so certain of it I’m willing to bet case of Kirin Ichiban that the Jazz board will get me cooling the brews again in no time. APDepot has a “defrost kit” that comes with the board, some foam insulation, and a fan blade. Part # 12002754 $167.00 no core.
