Question about GE Refrigerators
Model # gth18ecc2rbb - ice build up in freezer then the refrigerator will not cool down. this is a frost free refrigerator - why is it frosting over. Have to defrost every week
Refrigerators that self defrost have three main components that cause defrost to take place. On your model GTH18ECC2RBB there is a WR55X10397 Defrost Control Board
This part is most likely the problem and is found inside the fresh food compartment and inside the control panel. The location is 257 in this photo HERE Sometimes the defrost control board will show burn marks but not always. The other two parts that may be defective are the WR51X10038 Defrost Heater
The WR51X10038 Defrost Heater is location 618 in photo HERE
and the=> WR50X10071 Dge refrigerator top freezer is frosting over - ba9f87d6-60d9-4ee7-b168-2123fa15d7a2.jpgimages/ba9f87d6-60d9-4ee7-b168-2123fa15d7a2.jpg" alt="ba9f87d6-60d9-4ee7-b168-2123fa15d7a2.jpg" class="h_mi" />
The defrost thermostat is location 630 in photo HERE a tutorial of how to test the defrost heater and defrost thermostat can be found on the parts pages listed above. I will try to put the defrost heater test below. I think the defrost control board is most likely the problem here so look it over first. Manually defrost the evaporator with a hair drier so you can remove the defrost heater and test for continuity. I am here should you have questions Thanks Sea Breeze

your sure the defrost cycle works? sounds to me its not. you need to remove the freezer back and check the defrost components. or put it in the defrost cycle and see if it is working. to get that much frost as you describe the dor would have to be left open. also check all door seals. let me know what you find and we can go from there

SOURCE: freezer no frost
This is probably due to the failure of defrost timer or the heating coil..Try this
1)The defrost timer is sometimes found behind the front grill of the refrigerator. It may also be found behind a cover plate inside the refrigerator or freezer, in the temperature control console, or behind the refrigerator near the compressor.
The timer is usually held in place with one or more screws. Remove the screws and gently pull the timer out far enough to disconnect the wiring connector.
Locate the timer switch and turn it clockwise until you hear it click. One click and the refrigerator shuts off = defrost mode, second click the compressor and fans come back on = run/cooling mode.
2)If this doesnt work then Test the heating element for continuity using a multimeter. Set the multimeter to the ohms setting X1. Place a probe on each terminal. The multimeter should display a reading somewhere between zero and infinity. Because of the number of different elements we cannot tell what your reading should be, but we can be certain of what it shouldn't be. If the reading is zero or infinity the heating element is definitely bad and should be replaced. Proper power ( careful!! ) to the heating element ( 110-120 volts AC ) and the defrost heater does not come on = bad defrost heater.

Sounds like a defrost problem. Check to see if
there is any frost buildup in the back wall of the freezer. If so, it is not
defrosting as it should.

I had the same trouble. I found out if you have the digital display of temperature type of refrigerator adjust the freezer temperature to +5 degrees. The defrost systems uses a circuit board type. Not sure how it works. I took the back panel of and looked at the board. Did not see any manual defrost methods. I had to remove all the contents of the freezer and manually defrost. have not a problem since.
