GE refrigerator not defrosting

Thanks for your response. I did check the defrost thermostat and I do have continuity. I would be interested in knowing how to force this unit into a defrost cycle. What do you think about the thermisters being bad would that keep the unit running all the time?

To force this unit into a defrost mode, unplug the fridge and remove the cover from the main control broad and remove the main wire harness. (Three wires, Black, Blue and Brown I believe) Next take a a small 3in wire and bend it into a U shape to make a jumper.

Insert the jumper into the main wire harness to jump the to outer wires together. (Black to Brown) It should be pretty easy to slip it in through the back with the rest of the wires. (Don't worry this test will not cause any harm to your fridge)
Now reapply the power to the fridge and check the defrost heater. As long as the defrost thermostat is below 15 degrees then the heater should start working. If the heater doesn't work then there is a problem with either the defrost thermostat or the heater. GE uses a glass tube heater with a coiled wire inside. This wire has a habit of breaking after a few years.

As far as the thermistors go, all the do is tell the board to cool. They can make the unit cool all the time but the board should still defrost the evaporator every 6-36 hours. If the unit starts defrosting then you have a bad board.

Hope this helps and let me know if you need any clarification. Good Luck!

GE refrigerator model GTS18DC. Freezer is as cold as it should be. The refrigerator isn't getting cold. What could this be? Thanks!


freezer blows cold air to fridge, sometimes freezer freezes at back and blocks holes for outlet to fridge, defrost and restart, or take back panel off freezer and chip clear

Ge refrigerator top freezer is frosting over


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
e09a6ac4-8e1a-421f-a2da-14ff1c386c84.jpg

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 Defrost Thermostat

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

GE GSS25KGSAWW side by side refrigerator not cooling properly. We pulled the defrost heater out after thawing the freezer and the glass tube is discolored but I get continuity reading across it. Should I...


Hello,

Since the heater has continuity it is good and does not need to be replaced, the other parts that can make a ref. not defrost are the defrost thermostat or the defrost control (mother) board.

To check the defrost thermostat it must be checked when cold,when cold it should have continuity on it. The defrost thermostat is in the freezer clipped to the TOP of the evaperator coil usually on the right side...this is what it looks likeoldtech2332_122.jpg

If the defrost thermostat has no continuity when cold it is bad and thusly the problem...if it is good and has continuity and already having determined the defrost heater is good..the problem is going to be the motherboard since a part of it is the defrost control.it is the back of the ref.on the left.

The part numbers are

DEFROST THERMOSTAT...... WR50X10068

MOTHER BOARD..... WR55X10942

I have a GE refrigerator modelGSL25JFPHBS and I think I have a defrosting problem because the evaporator was a solid blck of ice. Can you tell me how to check this to see if it is working, is there a way...


you can jumper the board where the line cord enters the board,it will say comp/defrost/neutral in the center,jumper between the center terminal and the outer one that says defrost,if it still doesnt defrost you need to disconnect the defrost heater and check for continuity,then do the same with the defrost thermostat,but the thermostat needs to be below freezing to test it or it will show open(bad) the heater will show some resistance to be good

Defroster not working


First, locate the defrost timer which may hidden behindcorners of the fridge at the back bottom, in some models located in the ceilingof the fresh food section or behind the cold control cover. Once you locate thedefrost timer, slowly turn the screw in the middle of the defrost timer withstraight screwdriver until the fridge shuts off. Now it's in defrost. If thedefrost heater(s) starts, replace the defrost timer and defrost thermostat. Ifthe heater(s) does not start, unplug wire cord to check ohm test for continuityof heater. If continuity is there, plug cord wire which gives power 120volts(check specification) to heater. If heater no starts, bypass defrost thermostatby join the 2 wires in the defrost thermostat. If the heater now comes on,replace the defrost timer and defrost thermostat. If the heater itself is bad,replace it. Thanks and hope helpful.

The freezer coils load up with ice and stop air flow to the refridgerator and freezer


Likely Defrost heater built into coils. Secondly defrost thermostat mounted at top of coils or computer board in rear that controls defrost cycle. Check heater and thermostat continuity first after unplugging unit.

GE TBX18BLJ --Freezer comp frosts/ices up. Defrost


The next step would be to unplug the refrigerator and remove the rear panel and defrost so that you can unplug the defrost heater on one end and check the continuity. 305175 Defrost Heater and defrost thermostat Part number 3489. If you change the defrost heater you should also change the defrost thermostat. Let me know the results. Remember above 60 degrees the defrost thermostat will show open with your OHM meter.

Where (specifically) is the defrost timer located on my GE GSS22JEMD (Side by Side) Refrigerator? How Do I check to see if my thermostat is working or not? Please help.


The timer is controlled inside the control board on rear of your refrigerator. Four possibilities are the defrost element, defrost thermostat, Temperature CLIP EVAP THERMISTOR or the control board is defective. Let me know if you would like me to help you on this, Thanks, Sea Breeze

GE side by side refrigerator defrost problem


CHECK THE DEFROST HEATER FOR CONTINUITY. IF IT IS O.K. CHECK THE ELECTRONIC CONTROL FOR A FAULTY SOLDER CONNECTION ON THE DEFROST RELAY. THE ELECTRONIC BOARD SHOULD BE LOCATED ON THE BACK WALL OF THE REFIGERATOR BEHIND AN ACCESS PANEL.
