      Returning guest presenter Aaron Wilson is back for another exciting discussion. This time, we'll be talking about...
      The Science of CYA: How to Keep the Customer Safe, Document Your Work, and Not Get Sued
      We take on a lot of liability as appliance repair techs, and that can get us into sticky situations whether we've done anything wrong or not. Aaron will be teaching us all about how to navigate this side of the trade.
      We'll start by going over a tragic, real-world case study where a sloppy installation had lethal results, analyzing exactly how the installer's negligence caused this. From there, our scope will expand to what kind of safety precautions we should implement in our own work, both for the customer's sake and for our own.
      But even if you do everything perfectly, there's still the famous "technician witch hunt." Well, we'll also talk about how to deal with that by thoroughly documenting your work and putting yourself beyond legal reproach.
      A little about our guest, Aaron Wilson:
      Aaron has been in the appliance repair trade for about 15 years, starting out by doing installations before moving on to bigger and better things. He worked for C&W Services as a Sub-Zero authorized servicer for a time and thereafter joined Mr. Appliance of Highland Park in the Dallas area, where he worked for years as the lead technician and field service manager. These days, he's making sure that all the appliances of everyone's favorite fried chicken place are in tip-top shape as the Quality and Performance Consultant for the southwest branch of Chick-fil-A. In addition, he has taught many classes on refrigeration repair and advanced diagnostics, during which time he also developed training material for the soft skills side of things, which he is delighted to share with you. On top of all that he's a certified graduate of the Master Samurai Tech Academy, so he knows his stuff!

This unit was manufactured in 2009.  The other older icemaker service manuals I've seen have different controller operating parameters and different diagnostics.

Thanks for the links. Unfortunately that literature is from 1999 and the software and control board are different. I have been searching but have not found any data for the unit I've been trying to repair.

What is the issue with the unit your'e working on?

Unit stopped making ice. 

Unit running ... refer system seems OK.  But recirc pump is cavitating.  Insufficient water in tray.

Water flow rate is good on fill.  I wanted to run the diagnostics, but the push buttons did not work very well.  So I ordered a new push button board, the membrane for it and a new water level sensor. Put it all in, did the start up and left. On the return trip the unit had not produced any ice.  Test ran it and there was some ice, but the cutter would not cut the thin slab.

A check indicated that the plug for the heater wire had a bad connection.  Fixed it.  Tried the diagnostic tests, but the results are way different than those described in the service book I was using. Circuit board (main) is p/n: 2304129 rev B

Ice maker mfg: 08-09 

More tests ... start up ... water fills for 35 seconds and just touches the level sensor.  Unit runs refer system for 28 minutes then the cycle changes.  Cond fan off, HGBP energizes.  The ice slab is thin due to the lack of water. So ... there is insufficient water in the tray and I had installed a new sensor (2313643) new switch (control buttons 2304121) and a new overlay (2313692) 

The diagnostic test ran through the cycles quickly, so I recorded it so I could document it.

9 seconds Compressor runs LED: Service

5 seconds Water fills LED: service blinking, clean cycle

5 seconds Condenser fan runs LED: on/off, clean cycle

5 seconds Hot gas bypass opens LED: on/off, service

5 seconds Recirc pump runs LED: on/off, service, clean cycle

5 seconds Drain pump runs LED: on/off, clean cycle 

I suspect the water sensor, but I already replaced it.  Could be the connector ... I can check again, but I don't understand the filling

sequence or how determine the problem with that part of the system. 

=== I returned after getting some advise on another forum. (1) the water valve might be bad. (2) the refer system might be weak.

Evap temp was -10 deg F at the beginning of the tubing and +32 deg F at the end of the tubing ... with water flowing and a thin ice slab on the evap plate. 

I don't know how to proceed. 

The water flow during the fill cycle is very strong.  But it only adds 16 fl oz of water.  It takes 42 fl oz to fill the tray.

Does the water valve control the amount of water, or is it the control board and level sensor?  The level sensor has been replaced. If I

could get the correct diagnostic literature ... I was using 4317408.PDF  I could probably determine the real problem.
