Where is the control board located ? To repair howling noise on GE side by side. I've read if the control board is replaced this will corect the problem.

First of all - make sure you route the green grounding wire connector from the board to one of the screws, holding the board cover. If you leave it hanging - you can kill the board if the wire touches some of the board elements.

Second - check what kind of sensors you have in your fridge. There are three of them: one in the fresh food section, and 2 in the freezer.

If any of the sensors has black compound where the wires enter the white plastic cylinder, you'll need to replace it with the newer one: WR55X10025

Locations: One behind the damper cover in fresh food section (far left top corner)
One in the far left bottom corner (small cover with 2 white wires to it)
One (which most likely makes the problem) is on top of the evaporator (coil in freezer section, behind the lower back cover). Ifyou replace any of them - make sure to insulate the splice points with food-grade silicone.

Ok nx , I will try to help you .
1 ) unplug the refrig , and on the back , remove the panel covering the
board.
2 ) unplug the blue conector on the board , with 3 larger wires connected to it . looking at the connector , you will see
wire1 , wire2 , space , wire3 .
3 ) find a short piece of insulated wire , and strip both ends about 1/2 inch , and insert one end into wire2 , and the other into wire3 . Leave the connector unplugged .
4 ) plug in the refrig . After about 1 min , look inside the freezer , at the bottom , looking for a red glow . If no red glow , then the problem is the heater or defrost thermostat ( the 1" cylinder , with a pink and blue wire going to it , clipped to the top right on the coils ) . If you replace the heater , replace the defrost thermostat also .
5 ) if you do get a red glow , then the # 4 thermistor is probably bad . This is the 1" white torpedo looking piece , with 2 wires going to it , clipped on the top left of the coils . This thermistor works off resistance by coldness , and sends the signal to the control board . When the control board registers this resistance for so long , it will go into the defrost cycle , causing the heater to come on .

The fan howling , could be from trying to pull air up thru the frosted coils. The # 5 thermistor , located at the bottom of the freezer , slightly foreward of the drain , inserted into a holder , with 2 white wires going to it , tells the control board what the freezer temp is . This thermistor , could be bad , varying the resistance message to the control board , causing the fan speed fluctuations .

Bad computer board in back of fridge, unable to control motor speed causing motor to hunt

I don't see anything located directly behind the icemaker on this model. Try to better isolate the location of noise if you can. If the icemaker is at fault, I wouldn't bother trying to repair. Order another one. One other thing to check is the water flow. When the noise happens again, stick your finger in the ice mold and feel for water. If it just filled, then problem may be in the water valve. Hope this helps,

hi thanks for the question that noise is the fan in the freezer.you replace the fan motor the water disp problem is the little switch inside the freezer door difficult to get at please accept with a positive feed back thanks the appliance doc

FAN MAKING NOISE BECAUSE OF BAD COMP BOARD, PUT UP WITH NOISE OR REPLACE EXPENSIVE BOARD

the problem you are having is in the main control board. ge has had a problem with this part causing the fan motor to go into high and low speed which causes the howling noise. unfortunately it is a costly fix, around $125 for the part. if you are savy to changing this part it is a matter of unplgging about 5 connections and replugging them. the new board has an extra set of pin that nothing connects to. READ the instuctions and it is a simple fix, saving about $50-60 in labor costs.

I have had a number of these complaints and I have always repaired it by replacing the evap fan motor. It is a much cheaper part, however, its way more difficult to install than the main board. Yes many other techs say it can be resolved with a new main board and yes it is just a matter of plugging the wires in. I would be very interested to see if indeed it does resolve the howling. It will come with an instruction sheet that says you will need to cut a wire from one of the harnesses. Just disregard this if indeed your model is the one that you selected and is fairly new. (PSS26msr). If you would like to take advantage of my employee discount I can send you the part for $100 plus $20 shipping. Just let me know.

I found this website about 2 weeks ago. I and read the postings about replacing the control panel. I own the GSS22SGRF SS. This thing was driving me and my wife absolutely insane. We live in a smaller house and the howling noise was so bad we could hear it over the TV at normal volumes. I would have to crank the surround sound to not hear it. They are not kidding when they say it just gets louder. Anyway a year after it has been doing it or about 10 days ago when I ordered the control board the refrigerator stopped dispensing water and ice along with making a clicking sound. When I opened the door the digital temperature setting displays would turn off and on in succession with the clicking noise. I was like great, I just dropped $100 dollars on this control panel and 2 other things are now going wrong with my fridge.
Anyway I get the part on Wednesday and waited for my dad to come over and help me out just in case. We pull out the fridge and I am not kidding but it only took about 10-15 minutes to swap out the panels. All of the wires on this model come with connectors so we didn't have to cut 1 wire, all you had to do was plug them in and set the ground. I could have done it myself, too easy. We plug the thing back in, put it into position and BAM!!! everything is fixed. The water and ice machine are back to normal, not one howling or clicking sound for over 24 hours now. Best $100 I have spent in a while. Would have costed me a $100 just to have someone come out and look at it. I will never buy a GE refrigerator again based on the customer service I got when I called in but if it wasn't for this post I guess I would be out of pocket another $1900 because I was about a day away from throwing this thing in the trash!!!! GE NEEDS TO REALIZE THAT IF THIS PROBLEM IS HAPPENING THIS OFTEN TO STEP UP AND AT LEAST SUPPLY THE REPLACEMENT PART. I GUESS THEY HAVEN'T FIGURED OUT THAT THIS MIGHT NOT COST THEM RIGHT NOW BUT IT WILL COST THEM AT LEAST ONE PURCHASE IN THE FUTURE.

I think I have the same problem. The unit is also about 2 years old (GSH25KGRBB). I have an extended warranty. They already replaced the controller card. I see it is the exact part number you have mentioned. It seemed to help for awhile but I think it has gotten worse again. The noise is more consistent after they changed the board. Less revving up to "turbo" mode. Howling is a good description. I can hear it now, on the other side of the house. I would change the fan out. I think they did the board first because it probably is easier even if the part cost is higher. I will probably call them back again. This will be the third time. The first time they just changed the little flapper on the ice dispenser. Otherwise the unit cools and runs flawlessly.
