GE SxS dispenser inoperative
« on: November 26, 2013, 06:59:32 PM »
Hi everybody!

Working on a GE Profile SxS model PSS26NGSCWW, S/N SH40407 and need some help figuring out how to troubleshoot the dispenser controls. Customer advises that unit appeared to be operating normally other than dispenser. Dispenser board lights up as it should, but there's no response when calling for water or ice. Also, when requesting to dispense ice or water, the lights just go out. Temps appear normal and main controls appear to work properly. No sign of error codes

Mini-manual I found under unit behind toe grille is one page with tech data on one side & wiring diagram on other (P/N 31-51627), with no instructions on running diagnostics.  :tickedoff: I looked through the list of GE service manuals and couldn't find one that covered this specific model, so not sure how to run on-board diagnostics.  ??? This unit has simple lights on dispenser housing and a touch control panel inside the refrigerator compartment with multi-digit readouts.

Since all else appears to be working, I am leaning toward the dispenser board being the culprit, rather than a main PCB. It appears that this unit uses a bus line for control communication, so no way to check for direct circuit issues. Any direction on troubleshooting this would be greatly appreciated!

Thanks & wishing everyone a Happy Thanksgiving!  :cheers:

Hi DAB:

Thanks for the tip. I had read a few things that pointed toward the power supply in the main PCB, including where the caps for the power feed to the dispenser on the main board were being found with bloated tops and were bad. I worked for Frigidaire for many years, and we saw problems with caps in the early to mid 2000's as well. Thing is, I would like to troubleshoot this out as deeply as possible though, since both the main PCB and dispenser boards are not cheap! I don't see physical deformation on the caps, but that doesn't mean they aren't shot either.

Take care & thanks again,

JAD

Seen that problem a few times. Always been the main board.

Thanks guys.  :thanks:  I appreciate the input. Sounds like the main board is a pretty sure bet then. I had read a service bulletin issued in 2006 from GE about those boards having issues, and this unit is a model noted in the list, and falls very close to the build date range mentioned in the bulletin.

Have a great Turkey Day!   :cheers:
