The first thing you want to do is open the freezer and see if the fan inside there is running. The reason is the freezer cools the refrigerator side by circulating air from the freezer. If the fan is running then your problem is one or more parts of the defrost system is malfunctioned and in return your problem arises. There are three parts to the system, the defrost timer or in some cases control board, defrost thermostat also known as a bi-metal, and the defrost heater. The defrost system is set up to operate as so. The defrost timer or control board will turn the machine off, in some cases every 8 hours, some 12. During this time period the defrost heaters, located behind the freezer wall and rest underneath the evaporator, yet wires to them run up the side of it, are energized and emit heat that raises upward to melt the ice that has formed on the evaporator coils. The bi-metal or defrost thermostat is at the top of the evaporator. When the heat from the heater starts to reach the bi-metal, it breaks the circuit turning the heater off. The whole purpose of this is because the freezer cool the refridgerator side by drawing air across the coils and blowing to the other side via the evap fan motor. In my opinion, if you change one part of the defrost system change them all because usually when one part fails another will follow, so save yourself the time and the food loss, the cost difference is minute.

You have a defrost problem, which means the problem will continue to reoccur until you fix the bad part of the defrost system. Being that it's a GE, my first guess would be the heater, but you need to check to be sure.

Pull the interior panel of the freezer back off and check the defrost heater and defrost thermostat for continuity. The thermostat needs to be cold when you test it, so leave a good amount of ice around it. If both of those test good, then the main control board (which controls almost everything on that unit) is bad.

When you find out the problem, replace the bad part and defrost the system manually again with a hair dryer.

Here are some photos to help you identify the parts to check, just in case you're not familiar with them. The control board is located on the exterior back of the unit, behind a small panel.

Most newer GE fridges have dc fan motors controlled by a computer board. Sometimes the board just fails and sometimes the fan can cause the board to fail.

I had this problem...my frige is gss20iejp and it was the defrost heater. Very easy to replace yourself if you're good with a screwdriver. Repair guy wanted 200 bucks. I fixed it myself for 40, but still had to pay the guy 30 bucks to come out. You have to remove everything from your freezer, shelves, etc...

Then take off the back panel.

Coils should be completely frosted up.

Defrost heater is at the bottom. It is metal. Should have 2 screws to remove and Conected by wires on either side, they pull out from the bottom, just tug them. Replace with new defrost heater...your problem will be solved.

If you have any more questions, email me [email protected] and I'll be glad to help you out. I know how frustrating it can be if you don't have the funds to pay the repair guy and know you can fix it yourself with just a little advice. :)

My up right freezer in frosing at top inside part of the unit.

Frosting on evaporator coil should be evenly distributed all over the coil. If the frosting only appears up on the top around where the refrigeration line enters then the gas pressure is too low - if you add refrigerant the frosting will move down to cover the bottom coils also.

Fridge warm. Freezer frosting over. I've

Hi


Check the back wall or floor of the freezer section for frost. Check the freezer ( evaporator) fan to see if it is running. Check the condenser coils under the unit for blockage from dust. Check the condenser fan (under the unit) to see if it is running.
If you have frost in the freezer there is a problem with the defrost system and the freezer will start to warm eventually as well as the fresh food section. If that is the problem you can check the defrost terminator, defrost heater/s, and the defrost timer or adaptive defrost control If used on your unit or the main control board if so equipped. These things usually require dismantling the freezer and other areas of the refrigerator to be checked.

There can be many factors for the no cooling factor: the condenser coils could be blocked with dust, the condenser fan could be bad or stuck, the freezer fan could be stuck or bed, the freezer coils could be blocked with frost because the self-defrost system is not working or the compressor is not running because of a bad relay etc.

Freezer is "frosting over...refrig part not cooling????

it sounds like the defrost system is not operating and getting rid of the frost. the common fault is that the defrost heater has gone, or the heater cut out has gone or the defrost timer is faulty. how is the door seal in the area- that can cause frosting with warm air ingress.
