Refrigerator & Freezer Repair

[B]Hello all,

I have a GE Model GSH22KGMBBB Side By Side refrigerator and had an issue where the unit was not cooling. Took off all the back covers inside the freezer and found the coils froze up…
Did research and tested the defrost heater. BAD. Went and bought new one locally and installed. Unit ran fine for week and half and now doing same thing.

What else could be the culprit? :confused:

Could it be:

[/B][B]Thermostat def

[/B] [B]Part Number: AP3884317 made by GE

Can this be tested? If so what is the procedure? :wink:

This has been getting frustrating.

BTW. Parts that I have found on here have been cheaper than other sites I have looked at… Plan on ordering It from here if this will help fix it…

In the back of the fridg., pull off the metal cover from the motherboard. Unplug fridg. and remove the four pin power connector. Note which pc board pins are labled "line and defr." Put a jumper between the same connector pins and plug in fridg. If it defrosts, replace motherboard and evaporator thermister. AP4436216 for motherboard, WR55X10025 for thermister.

Thanks for your reply.

I just got done doing what you said and thought at first it still wasn’t working cause the element didn’t heat up as fast as I thought. But sure enough open the door again and was glowing red. Other than MB, Is there not anything else that would stop it from working?

Also I look at the parts list on here and could not find what you suggested for part "Evaportator Thermister WR55X10025". Is it not avalible here or is it called something else?
Never mind, I found it… Its called something else and with different part #.

[INDENT][COLOR=DarkGreen]Ok Replaced this part, been 3 days and still seems to be frosted up. Any thing else other than the MB?:mad: Guess MB is next :eek: :rolleyes: :mad:

EDIT: Well scratch that above. After I posted this I went back in there and looked at it and the defrost heater was ‘ON’. So this rules out MB.

I took some pictures to show cause not sure this is normal or not the way it looks.

Also the fan back there is making a reving noise. You know when you rev an engine?? Throttle then let off then again etc… Never noticed before but would that cause what is shown in the pic… [/B][/COLOR]

The evaporator motor should not be on when defrosting. Replace the motherboard.

Will you stop with the motherboard, Sheesh :stuck_out_tongue:

I had the door open for a little while looking at some things. Then it turned on. So its not suppose to?

Listen to the man already… replace your motherboard. Looks to me like you have one of those rare conditions where it’s trying to cool AND defrost at the same time. Where does that all happen… at the motherboard.

You used your 1st post to be a smartass? Get back on your barbie bike and go bake some brownies. :mad:

I’m trying to look at all angles before I go and drop over $150 for a board at the moment.

Hey, Take The Defrost Thermostat Out When Is Frozed And Check For Continuity, It Should Be Close, Then Heat It Up With A Heat Gun, Or A Blower, If You Dont Have One, And Check Continuty Again, If Still Close, Replace It, If It Is Open, Then Replace The Motherboard, Those Are The Only Parts Involved In The Defrost Process.

Thank you I will try that… I am on the road right now so will have to wed or this weekend…

I read that when the thermostat goes out ( that is the one pictured at above right?) that it melts or breaks open. is that true?

But I will check it out and post back.
Thanks again for the reply.

Hi MacGyver
Where did you buy your jumper? I looked at a local Radioshack but they didn’t carry any jumpers.
I would appreciate any info.
Thanks

I didn’t buy it, I made it…:cool: Just get you a connector kit or just buy the male spade connectors and get a wire and connect them… Paper clip could work too but make sure power is unplugged before touching the clip… :stuck_out_tongue:

That’s good info!!
