This part assembly has 2 functions: The defrost heater keeps the cooling coils from frosting over and the thermostat senses that the heat near the cooling coils has reached the desired temperature. Used with side by side models.

My refrigerator is "Cool" again!
When I noticed that my refrigerator never seemed to shut off, I found the usual condition that exists when the defrost coils stop auto-defrosting. The freezer was sill freezing, but the refrigerator was getting warmer inside. That indicates that a glacier has formed on the coils in the freezer and the fan can no longer push cold air over into refrigerator side because the ice is blocking the air flow. Removing the panel covering the freezer's coils confirmed my suspicion. So I ordered the replacement defroster "kit" from PS. I asked for expedited delivery and it came without any trouble. Once I had the parts, I proceeded to install them. PS's video instructions are excellent, but I would like to add that you may have to use a hand-held hair dryer to thaw the "glacier" out. Just put a pile of bath towels into the bottom of the freezer to catch the water as the drip pan will easily overflow if you don't. It takes a total of about 1 hour, including defrost time to do the job. PartSelect is a great resource

Suggestion- even though tubes are available separately the time to rewire into the existing harness to save couple $$ is not worth it- the other unit will have lost some continuity in comparison to new install so will have tendency to go bad quickly-spring for the difference and have piece of mind for many years to come for replacement of this part. 2 day standard shipping by ground right to door and the little woman thought I was superman of repairs. Since this model was built by GE for Sears- check on Sears was double and inquire in tech repair was double again-Part Select is quality,speed in processing and makes tight budget go the distance.

Freezer and Refrig warmer than should be, with thick layer of frost build up on back wall of freezer compartment
From reading other customer reviews I initially suspected the defrost timer located inside the refrig compartment behind the upper back panel where the light bulb is located. Was able to order, remove shelving, remove cover panel, locate, and do a simple remove and replace. However, after I had manually defrosted the freezer (by unplugg
... Read moreing and leaving door open all night), the original problem reoccured within a few days. Next step was to suspect the heater coils located inside the freezer compartment behind the back wall panel. Sure enough one of the two coils was burt, by having a black color to the coil. Was able to order this ready to install kit, that includes both new coils, and thermostat as one assemply, and again do a pretty simple remove, then install with new, exactly as the original. No more frost build up, and both compartments are nice and cold. These are simple and basic part replacemts, and PartSelect makes it even easier. There was no reason to replace this side by side that is now 15+ years old and counting.
Note: If a heavy build up of frost has occured, defrosting will most likely create more water than the tray on the bottom of the refrig can hold. Will need to plug or tape over the drain hole on the inside bottom of the freezer compartment. Large bath towels can be placed on the bottom of the compartment to absorb water, and prevent over flow onto the floor. Will take several hours to completely defrost. Foods can be stored in ice chest or seperate freezer if available. Others have used heated blow driers to reduce thaw time.

Freezer was cold but refrigerator was hot
After diagnosis though Part Select I determined it must be the defrost heater. I took the panel off on the inside of the back wall of the freezer and used a hair dryer to thaw the ice buildup.

The refrigerator section of my side by side was not getting as cold as it should have been.
It was easy after finding PartSelect online. It wasn't obvious at first that my evaporator core(in back of freezer side) was frosting over, (since I have a flat white panel that is about 8 x 30 inches covering it), until I reached inside and ran my fingers over the cover and noticed a thin layer of frost on it. At this point I told my bud

After taking the 9 screws (6-1/4" hex heads & 3-#2 phillips)out and removing the panel, I saw that the evaporator core was completely frosted over. I then put a large towel in the bottom and let it thaw for a day. Next day after getting the old Defrost Heater Kit with Thermostat out (4-#2 phillips, plug-in electrical connection, thermostat snap on clip) , I noticed it was burnt inside the filaments and did not pass the continuity test. I then ordered my part from PartSelect and took the oppurtunity to clean my fridge spotless. 3 business days later, I received my part, installed it, and now have a "like new" refrigertor. Actual repair time - 30 minutes, Overall down time - 4 days, Saving the cost of a new Fridge - a heck of lot more beer!

Is there anyway to test the defrost heater assembly through the pigtail? My defrost timer seems to work correctly but when the defrost cycle "clicks", the heaters do not activate.
For model number TFX22ZRXFWW
Hi Jamie, Thank you for the question. You should be able to tell by looking at the heater if it is defective. The glass will be clouded or have burn type of marks. The thermostat you can test. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

Freezer side gets cold then it gets warm would this part fix the problem or is there another part that would work better thank you
For model number TFX20JRBCWW
Hello Mike, Thank you for your inquiry. We would recommend checking the defrost heater, timer and thermostat together. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, there are YouTube videos available to assist you. Hope this helps!

The freezer and refrigerator are not cool. The compressor is running. How do I determine what is wrong? What could be the problem? The water appears to be working. Electric heater under ice cube tray is not working. The blower fan by the ice cube tray is working. The coils under the refrigerator by the compressor are room temperature, not hot or cold. Thank you!
For model number Tfx22zpbbww
Hi Jay, thank you for reaching out. Based on our understanding of the issue, we would suggest replacing the defrost heater with thermostat, part number PS303933, to solve the problem. We hope this helps!
