hi all! i have a GE sts22icmarww top freezer. it got to where it would stop running long enough that things in the freezer would start to defrost. sometimes unplugging it & plugging it back in would get it started. so i did some research & decided it was probably the mother board. i ordered a WR55X10656 board. i found this to be the replacement for the factory EBX1005G01 board. i installed the new board & guess what? NOTHING! the only thing that works is the light. fans don’t run, no clicks from the compressor , just nothing. anybody got any ideas? please let me know. thanks alot! Anthony
These motherboard refrigerators are hard to work on. Remove the cover from the motherboard and measure the voltage from the main 4 pin power connector, comp. pin, should be 115 volts to common white terminal. If not, you will need to check things per the South Jesey data sheet found in my article in the "sticky" GE GSS and PSS refrigerators.
You might have a intermittant power line or a bad encoder control in the fridg.
richappy , thanks for the quick reply! i finally got around to checking the voltages & as far as i can tell there is no power to the board. i probed every contact on all the plugs at the board & nothing on all of them. (i put ground probe to the metal backing on fridge.) there are plugs for the J1, J2, J3 & J7 points on the board only. is there a junction box or something that directs power to different parts of the unit? i also checked the J2 pin 1 to pin 3 check with 0 voltage also. any other suggestions? thanks again, anthony:(
just checked power wire going in from 120v plug. there is 120v at one wire in 6 pin connector. the other wire from the power wire goes into a white connector of some sort & comes out as 4 orange wires that go to capacitor & compressor and the other 2 , one goes to the 6 pin conecctor, the other goes into main harness.i probed the 2 wires on the compressor relay and the black wire on the overload. 0 volts at all points. also checked the capacitor it check out as open using the ohm setting across the 2 terminals. (not sure if that matters?) its almost looking like the power wire may be bad? thanks, anthony
come on fellas somebody got to have an idea. at least give me some direction to go in. thanks
Probably some connector pin came loose, just check.
applianceman, thanks for the advice. i unplugged it & still nothing. got any other ideas? if not i’m gonna chunk that SOB down the hill and go get a new one. thats the last GE for me. i’ve only had that POS about 7 years & this is the second time its died on me. let me know if ya’ll got any other ideas. i’m either gonna get it workin or blow it up tryin! thanks again, ant:p
[SIZE=3]Have you checked voltage from the plug marked line to the pin marked N on the bottom of the board? I did read all your post but I don’t know if you have checked this. [/SIZE]
[SIZE=3] [/SIZE]
[SIZE=3]I am with richappy I think it is a loose connection of some kind.[/SIZE]
[SIZE=3] [/SIZE]
[SIZE=3]If you could wait until Monday before you blow it up I will try to find a wiring diagram to it at the shop then I might be able to help more. But from what I gather you have probably already done everything I would know how to help you with. [/SIZE]
Also plug that encoder back in because it is not your problem.
sorry for the late reply. i looked that board over & saw just about every letter but N . i looked on the under side also. i found the LINE plug but not too much luck with the N. got a pic or anything that shows where it might be? thanks again, ant:confused:
[SIZE=3]It is the orange wire on the bottom white plug. The first you see going from left to right. [/SIZE]
[SIZE=3]Try this only if you get 120V from L to N (orange wire). [/SIZE]
[SIZE=3] [/SIZE]
[SIZE=3]You may have already done this if so let me know because I am not sure.[/SIZE]

[SIZE=3]You should see a plug marked J2 unplug it. Check for voltage between pins 3 and 8 on the board. If you get 12VDC there may be a short in the fan circuit. Post what you find. [/SIZE]
Check the defrost timer.
ok, not sure but my board may be laid out differently or something? i got 120v to purple wire on J7 plug from LINE . i checked every wire going to board & thats the only one that had anything. checked voltage between pins 3 & 8 on J2 , no voltage there. makin any sense yet? i’m lost. thanks again, ant
Check your thermistors on Ji connector, upper right. Check them per my article in sticky above "GsS and HSS refrigerators". You might have a thermistor disconnected, that would shut the fridg. down.
hi again. richappy, i checked the thermistor pins as you described. they all seemed to check out right, i think. (3.8ohms with meter on 20K ohm setting) but pins 5 & 7 are a dead short , as they should be, because the are spliced together. (2 blue wires). thats the reading i got from the J1 plug. i added a pic of the board & labeled the plugs. the board is actually mounted upside-down on the back of the fridge. maybe this will help with my confusion? 
thanks again, ant
thanks for the other info right now everything is ok but my main concern is my washer i realy need an answer if you can thanks.
[SIZE=3]On the J7 plug the #9 pin (orange wire) is neutral (common) the pin all the way to the left looking straight at the board. You should have 120V from Line to that wire on the plug. If not I believe that is your problem you need to find out why you don’t have the neutral to the board. You may have a loose or broken wire. I know you said you have voltage to the purple wire what pin was that? http://www.appliance-repair-it.com/Refrigerator-repair.html[/SIZE]
applianceman, not sure if you saw it but if you look @ the pic above, the purple wire is pin #6 on J7 plug. the orange wire didn’t have voltage going to it. ant
You don’t have any voltage from that wire to the Line wire (there should be). That is the wire that feeds the board natural. You need to look for places that this wire may be broken.
[SIZE=3]Do you get a voltage reading if you place one lead on line and one to ground (the green wire)? [/SIZE]
