Title: GFE27GGDAWW Diagnostic service error codes
Post by: TobiiFixit2 on June 10, 2021, 06:43:43 PM
Good day guys
I have a white GE 27 cuft french door Model GFE27GGDAWW.

I have the following codes from the diagnostic menu in the attached image.
 
things I noticed
1) FF section set to 1 c but hangs around 3-degrees c may fall to set point randomly
2) fresh food fan is not on for long periods then come on kinda loud
3) defrosts cause the temp to rise to 4 to 5 but lately it going to 8 degrees c now
4) fresh food section seems to be defrosting a lot

I'm not sure if anyone can help or decipher the codes I already have the service manual which is no help, and the mini-manual for the fridge does not have a list of what the codes mean.

I'm from the Caribbean btw Trinidad

Change that fresh food fan motor and you should be back in business.That fan can cause all of these! This should be your mini manual!Fresh Food Fan Contributing to Warm Temperatures



Possible Symptoms:      operating speed

That has all the error codes it.If that helps let me know and what they mean!

Thanks
will order it soon. The new fans seem to be made by AVC instead of Nidec and look more like a normal PC fan guess the Nidec failure rate was too high.
The mini manual for my appliance does not have codes and what they relate to.
 Thanks for that mini manual although the error codes most I got say N/A for most guessing since mine is the 2012 model with original board software may be different so codes may not line up.

This morning the fan is on and off a lot and temps are closer to 2c guess it's feeling to work today.
Question does the mainboard learn habits like for example we cook on Sunday to last the week so we are in and out the fridge.
so would the mainboard learn ok Sunday at 11 to 3 fun the fans on high as that's the time we usually in and out ?

Code             Meaning
0002              N/A
0005              Electric deli pan thermister out of range (mine is manual deli pan)
0007              N/A
0010              FZ Icemaker Thermistor reading out of range (my model does not have a freezer IM)
0011              N/A
0012              N/A
0203              5 consecutive FF extended defrosts (seems accurate at least 2 times a day it defrosts)
0300              N/A
0303              FF Temp Exceeds > 50 F (seems accurate also after some defrosts guess extended defrost will raise the temps to 8C or more)
0506

so opened the fridge to see what's up and to check the old fan model#, it seems to beaten up if you judge by the sticker. also looks like the original fan.
Wanted to make sure there was a rubber boot on the fan.

while the evap cover had a thin sheet of ice on it and was frozen down to the back wall on the left side, there was not much ice back there on the evap but there was frost by the bimetal thermostat, and non near the evap thermistor.

unplugging the fan did give a 106 error which is no feedback while the fan power on.

Seems to me the fan runs at only one speed since it's the same sound even when the fridge door was opened for a prolonged period. Speed control maybe only working for one-speed medium or high can't tell.
ordering next week just wanted to post this

How did you go with this, dab147315 could be on the money, but I would have expected to see a low target speed fan fault show up, since they have monitoring? If you haven't changed the fan, you could try a full manual defrost, leave it off for 24 hours doors open, and check all drain tubes are completely clear, then monitor closely and see if the same results occur? (Clear all fault codes first so you are starting afresh)  Also ensure you have a bit of space in the fridge, not too crowded so good airflow everywhere for testing.

The Fan was very noisy so I changed it. It's still loud but does not sound like a bearing has gone.
It seems like ice has also been frozen in the styrofoam so it swelled on the evap cover and where the fan resides so this may be causing excessive fan noise as its pressing on the fan amplifying sounds but no bearing grinding sound.

Since changing the fan it's still loud but consistent. I also notice the fan would be on then sound like it's cutting off but speed back up again for 10 min before going off.

I find after defrost the FF compartment seems like it's taking longer to cool down after a defrost which leads me to think thermistor.

the FF compartment is also set for 1c but it maintains 3 or v degrees c from the external display. I'm not sure if the ambient thermistor controls how the system runs but.
after changing the fan I cleared the error codes the ones below come back.

03 03  FF Temp Exceeds > 50 F/10 c. some times after a defrost it its 4c other times higher.
0506  idk what this means it's in the door board error codes but it's a N/A for explanation

In my mind since the freezer is fine its temp rage is -19 to -12 at lowest if we open it too much -10 defrost does not raise the temp much.

What I notice is the drain pan is dry on the side where the freezer drain tube leads but the FF side is usually half full.

I personally find some of the times the FF section defrosts too much. since during the week we are hardly in the fridge 3 times a day some times it defrosts.
Since changing the fan it defrosts 2 times a day and the fan is on longer.

so I wonder if I have faulty FF thermistors and the high heat limiter maybe toast?
The fridge is not packed to be honest so.

Service manual and my mind/interpretation say if it's set to 1c then the fan should be on until the FF compartment thermister says it's 1c then remain on low speed for cycle defrost. when the FF section gets to maybe 2.5c then the fan can come on to bring it down to temp. if FF section gets to 4c after defrosting which is ok in my mind when it comes out of defrosting FF fan should be on high till it cools down.

The freezer fan is always on no matter what tho.

I also had it in diagnostic mode reading the thermistors and I keep on seeing a 0101 flash in between the readings which is Fz fan feedback when fan should be off but that's not listed in the diagnostic error code read out so idk what that means.

wish I could send a voice not to explain better but let me know what you think and ask what you think you need to also added pics when i changed the fan had to use a hair dryer to remove the evap cover was frozen to the back wall.

Some of the following may be relevant to you. As dab147315 mentioned earlier, a low functioning fan can cause many problems. Airflow in these fridges is critical, critical in the fact that the right amount of air needs to go to the right places, and be returned, from the right places for the unit to function correctly. Overloading any frostfree fridge causes problems, blocking return air pathways with product, especially when things are pushed over the back of shelves, or shelves are stacked solid, will always cause sub optimal conditions as this can short circuit the airflow. Airflow around the evaporator is also critical, and any air leaks create big problems. I can see a couple of things that may/may not  need rectifying. It appears the cover is missing from the front of the fan housing. There appears to be silicone sealant or is it ice built up on the evap cover near the left air duct. It appears the foam seals are damaged or compressed. Where the aluminum foil pushes against the evaporator each end, it needs to seal, so if the aluminum is permanently dented, It's probably not sealing. One fix would be to buy a new evap cover. If it were my own, I would replace all seals, and you don't need OEM ones, you can generally buy glue backed foam from hardware stores used for  door/window draft seals in various widths and thicknesses. If the evap cover is warped in any way you will need to ensure thicker material is used to ensure a proper seal. You will also need it to be perfectly dry, or use other glue. The aluminum insulation, something could be slipped in behind it to move it forwards perhaps. The same goes for the freezer compartment! If part of the evaporator is not receiving correct airflow, then a few things happen, less refrigerating effect in that evap, uneven ice buildup on the evap, lower suction temps which the thermistors see which don't give a proper indication of the actual condition in the evaporator.

1) what you were seeing is ice on the left side near the deli draw air outlet.
2) the foam seals were wet when I removed them I dried it out as much as I could before reinstallation
3) the foam seems to be swelling in certain parts I let it defrost and pushed it flat water did come out so ice seems to be getting in the foam.
4) aluminium foil seems good

ill monitor it when I get home by mom the fridge is there
