Very good work, I had one last weak, the evaporator thermister was supposed to be 5Kohm, measured 160 ohm and it was soft and squishy like the thing got heat stress!!

To add on to this, I have a EBX1005G01 rev. M unit bought 09/2003...
I have read all the posts and have a similar GE/Hotpoint [S/S, same main board #, model# HSS25GFPA WW].
Quick history - compressor quit running so I put food into a spare unit. Just for fun I plugged it back in and it ran for a few days perfectly, then stopped. This pattern worked for 5 or so times and now only the lights and condenser fan runs, nothing else.
I have checked all that I can think of and have nagging "thermistor" questions. All 3 have approx 1200ohms each measured at plug #J1. BTW, where are they???
Power comes to the contoller board. Voltages are: J11[line] to: J9[defr]=120v, J8[comp]=120v, J7-N=120v, J7-dfz=120v, J7-dff=120v, J7-qch=0v, J7-common=0v, J7-water=120v, J7-crusher=120v, J7-auger=120v. I have also disconnected the encorder board plug with no change. I have triple checked all the connectors.
From what the Pros have written, it could be the board or thermistors. And I understand that bad thermistors can re-fry a board.
Any other help??? THANKS!

Thermisters do NOT destroy motherboards, bad motors do. Check the back of the motherboard for bad solder connections at the power relay.

Rich:
I've been out of town [still am] and will check the board when I get back home.
1--It looks like I 'release' the 4 plastic 'arrow heads' protruding thru the board to remove the board.
2--And where are the thermistors anyway??
3--So a bad solder connection is probably the reason that it worked and
then didn't and then worked and then didn't...?
Thank you again.

You will have to look at your parts breakdown for location of the thermisters; usually a big failure like this is not due to thermisters unless they are way off value.

This reply is information for a GTS22FB GE Refrigerator. I had problems
with the compressor not switching on, everything else was working ok,
I removed the motherboard P/N EBX1005G01 and noticed that there was
a relay pin contact that had a cold solder connection to the solder side
of the motherboard. Resoldered the connection, reinstalled the motherboard the compressor started to work, freezer and frig now ok.
