I apologize if this is redundant, but... manual please.

Manufacturer: Ge

Type of Appliance: Sxs frig

Model Number: HSS25ATHECBB

Have you validated the model number at an online parts site like Repair Clinic? (yes or no): Yes

Have you watched the video on how to search for manuals and have you searched the Downloads section prior to posting this request? (yes or no): Yes

I posted this previously and you gave me a Mini manual. But the schematic did not seem to match up with this: ( unless I just can't read which is emminently possible).  It had/has a severe Frost up on the evaporator and I replaced the nasty green heating element and I'm trying to check my thermistors,  but can't  seemed to match the schematic given with this. Thank you.

This is a screenshot of the Mini manual posted when I asked previously.

I see what you mean-- big discrepancies between the schematic and your photo on the J1 and J4 connectors. 

According to the GE site, the correct PUB number for your model is 31-51661. But when I shorten the model number even further, it pulls up an additional PUB 31-51964. This one shows the same configuration shown in your photo.

Thank you ever so much!

Anytime!

Okay I beg your patience yet again, but I do not see how this matches up.

For example: on the second schematic screenshotted below- If I test from the red / white wire on J 1-3 pin; to the blue wire on J1-5, I should be testing the freezer thermistor circuit.

BUT,  on my actual freezer board, the pin is called something similar yet different (J - 3) and it has no red/ white wire.  Additionally, there is no J1-5 with blue wire. Instead I have a J-15 with no wires on it at all.

I'm wondering if I am supposed to use that J-15 for probing the ground side. But then I still don't know which of the other multiple wires are correct for the thermistor circuit.

Please forgive me if I'm overlooking something stupid, but I have gone back and read my notes and I'm watching the video again but I can't make heads or tails of this schematic. Thanks in advance!

GE has some screwed up documentation for this model. If I shorten the model number all the way back to HSS25*, I get a dozen tech sheets, none seem to have the exact configuration on J1 as shown in your model. This is generally not a good sign, usually indicates a model that is seriously low-end or has been orphaned. Sorry we struck out on this one.

Well I appreciate your compassion, but I'm sort of relieved that it's just not that I'm THAT incompetent!  And I learned  something very interesting about Oddball scenarios/precedents like this. 

 And hey, I got a real person to tell me that very quickly.  So all in all, I count this a positive!

Thank you once again for your quick help, and I will plan to replace both thermistors. 

But please tell me this so I can better understand.

I suppose the PCM actually needs BOTH thermistors to correctly operate the defrost function. So in that sense 1 is not more important than the other though as you said the EVAP  thermistor is subjected to more abuse and  therefore more more likely to fail.

is that correct?

It’s SOP for me to replace the evap thermistor and defrost heater bimetal whenever I’m accessing the evaporator. The cost on these components is very low and they have a high failure rate, meaning if they’re not a problem now, they soon will be.
