Regarding GE french door model pfs221sbss, need

your main board in the back of the unit is bad and needs replacing,if you recently replaced a burned out light bulb in the freezer and now they strobe rapidly this is another good sign its this board the new board is a G.E. # WR55X10942

Had similar problem, freezer was working fine, but fridge was warm, (68 degrees) It wasnt my damper, the mother board was fried, and so was the inverter board that told the compressor what to do, after having the inverter and two mother boards replaced.......I threw it out, biggest piece of ****, only three years old, and Sears would not stand behind it, even though I used their repairmen. I will never buy another GE product, or enter a Sears store again

ER CO is an indication of a communication error between the display board and the main board. Has this unit had a board replaced recently? If so, one of the multi pin plugs may have not gotten connected firmly, or an incorrect board may have been installed. The problem has nothing to do with the dust.

That will happen easily if the temperature probe/thermistor is covered or located behind something stored near it. The door reading also could be out of calibration. If you have an ice maker the ice maker will not want to work very well above 5 degrees. If you run into major problems or this just started happening and you notice changes in the fresh food compartment goes above 38 degrees then that could be the beginning of a defrost problem. If you should need help let me know, Thanks, Sea Breeze

check the defrost thermostat , and any temp sensor that can determine the freezer temperature.
If this fridge temperature is electronically controlled, the freezer control board must also be tested.

If the panel temperature reads 0 F 0 F it is in the "DEMO" mode. This is normal if you purchase a floor model. To bring it back to normal mode press ENERGY SAVER & ADJUST FREEZER together for 3 to 5 seconds until it beeps. Then unplug the referidgerator for at least 30 seconds. Then plug it bck in. That will reset the stupid computer and get it back to normal operation.

I had a very similar problem with our GE refrigerator. The main control board looked to be the culprit. I took out the board and did a visual inspection. Upon inspection I discovered that the (2) 470 micro farad capacitors were blown. I checked the power diode near these and it was still ok. I went to Radio Shack and picked up two 470 micro farad - 35V capacitors for and grand total of $2.60 and resoldered them myself. The refrigerator has been running great since. If you want to know more details email me and I will be happy to let you know what I know. I didn't want to pay $100 for a GE guy to replace a board either!

Hi. Its either a bad motherboard or control board. I would check the control board for any obvious signs of damage to the board first. I've seen the control board go blank on the GE side by side and it turned out to be the motherboard. The motherboard is located behind a cover on the back of your refrigerator cabinet. You should have a new motherboard on hand at all times because they fail alot. Be sure to put a surge protector on your refrigerator. Good Luck, Mack

Wow, so you dropped some money into it, eh? I would take a look at the damper door asslb(DIFFUSER). located at the very top left of your refrigerator section in back. It has a motorized door that opens and close's and it may be stuck open. More than likely it is broken and needs to be replaced. GOODLUCK!!!!

FYI: All your cold air in your refrigerator comes from your freezer!
