Freezer coils freezeup fresh food side gets warm

The damper door actuator has failed.

Your problem is more than likely a defrost issue. There is ice building up in the freezer coils and when it gets blocked with ice the cold air cant blow into the fresh food section. When you shut it off the ice melts and it gets cold again for a few days. remove the freezer back panel and check the defrost heater and defrost thermostat. if they check OK then check the defrost timer. It is best to replace all three components at the same time. This way you will be starting out with new components rather than one failing then the other.

the freezer works ok..this is where the cooling unit is..so, if the freezer works ..its not blowing or allowing air to flow into fresh food area..if its missed its defrost..it will not allow air to go into fresh food area and you need to remove panel and defrost coils ..or see if blower is working...check for bad heater or defrost thermostat or what controls defrost ie timer or board

And you are posting because,.......????? You are looking for a second opinion? Don't like the repair estimate?
1. Your freezer is not working great. If it is frosting up, frozen packages will soon beging to soften also.
2. All of the cooling takes place in the freezer compartment. A fan blows air over the coils in the freezer, and directs some of it into the fresh foods side to cool it. When the coils become blocked with frost, the air can no longer flow into the fresh foods compartment. Result is warming of FF area. You may also see freezing in the bottom FF bin, water dispenser not working, FRZ section warm, etc.
3. Manually defrosting the coils will temporarilly solve your problem, but it will reappear in a few days to a week or so. (depending on door openings, ambient temp, etc)
4. The motherboard controls the defrost interval and (although not the most common) certainly can be a cause of defrost failure. If a qualified servicer diagnosed it as such, it most likely is just that.

There is a defrost timer that can be turned by a screwdriver until it clicks wait about 20 mins to see if advances if not, turn it some more to turn on ref and the timer is bad

You don't say why the mother board was replaced. Make sure the board was the correct one, part number WR55X10656 for your GSS22WGMD and that all plugs are firmly and correctly attached to it. If yes, then check the defrost heater (located behind the back wall inside the freezer, near the bottom) to see if it is burnt out. (If you disconnect the wires from each end of it and test, finding no continuity, it is bad) It is a part number WR51X10101 for your model, and is a fairly common failure point. While you have that apart, manually defrost the coils with a hair dryer. (the manual defrosting alone will get your refrig working for at least a week, allowing you time to get any needed parts.) If left alone without defrosting, your freezer section will not be working well soon either.

On my GE side by side (model GSS20IEMDWW), a warm fresh food side, as well as iced-over evaporator coils in the freezer, was caused by the temp sensor in the fresh food side sending faulty data to the computer.

The temp in the fresh food side would climb because air could no longer pass over the iced-up coils in the freezer side.

For me, the faulty fresh food side sensor made the computer always thing the fresh food side was too warm, making it constantly run the compressor (thus icing up the coils).

If you do not have a coil icing problem in the freezer, then your fresh food side temp sensor may be telling the computer that the fresh food side is already cold enough.

Hi: Your defrost heater or defrost timer is bad. There is an off chance your freezer or fresh food compartment are so full they block the airflow. If not full, Remove the food from the freezer, unplug the ref. and hit the back wall of the freezer with a hair dryer. Avoid plastic components as they will melt. When your defrost mechanism fails frost will form where it shouldnt and block the airway to the fresh food compartment. That's why the freezer still works. That will get you a week or two of fresh food getting cold. If your'e handy remove the back panel of the freezer at the bottom will be a glass tube with a metal coil in it. If the coil is broken buy the new defrost heater and install it. If not look for a defrost timer. Use the model number of the refrigerator to find the part. www.searspartsdirect.com will have a parts schematic to help you find out where the timer is located. There shipping is high so try to buy it locally. I hopes this helps, Jeff

If you have frost on the back wall of the freezer compartment you have a defrost problem. When the freezer coil does not defrost the refrigerator does not get air for cooling.

check the line temp(fuse) and replace sensor
