DFE28JMKKES General Electric Refrigerator - Instructions

luckly i have a bit of experience in refrigeration im an hvac technician by trade. this repair was a bit tricky in that i did not know at first if it was a Temperature Sensor issue or the main control board. I had tested the defrost termination thermostat and the defrost heater and as i suspected they were ok. Next i wanted to test the thermistors (temp sensors) it is hard to find technical data on these fridges. I needed to test the thermistors resistance @ a certian temperature to ensure they were working properly but where do u get such data? I also wanted to know some information about the logic programmed into the board (i.e when do you initiate defrost etc. . .). I had no such luck so i figured since i tested the defrost heater and thermostat and they were ok and all of the evap fans and such were working i'd order a circuit board and new thermistors. Got the CORRECT PARTS from this site in 2 business days and my fridge is working great! changing the parts was really easy, figuring out which parts to change was the only difficult thing about this job.

took out shelves and removed the back plate my removing 2 screws with a nutdriver.removed the old defrost timer and defrost heater which was really easy.then installed the new ones.the video i watched on the website was really helpfull.

1. Removed and tested defrost heater, tests good. 2. Reinstalled defrost heater. 3. Removed and tested defrost over-temperature sensor, tests good. 4. Reinstalled over-temperature sensor using soldering iron, dielectric silicone grease, and heat-shrink tubing. 5. Removed the control printed circuit board and checked for blown fuse's, fuse's are all good. 6. Removed the defrost relay from the printed circuit board using soldering iron, bench tested the relay, it is good. 7. Soldered defrost relay back onto the circuit board, and reinstalled control board. 8. Removed and bench tested evaporator thermistor, the resistance is out of specification, ordered new thermister. 9. Installed new thermistor using soldering iron, dielectric silicone grease, and heat-shrink tubing. 10. Re-assembled refrigerator. 11. Installed temperature monitoring and recording instrumentation for 72 hour test. The defrost cycle is running correctly with a defrost termination temperature of around 90 deg-f. The defrost cycle ran twice while running the 72 hour test. 11. Removed test instrumentation and Put the unit back into service, The thermistor was the culprit. I bought the right part on the first shot, nice.

My son replaced both temperature sensors and the fridge works great now!!! Like brand new again!!!!

Temp. Sensor was under an egg shaped cover on the left side wall in the refrigerator. Remove the cover, cut the two wires to the old sensor and remove it. Connect the new sensor to the two wires using butt connectors. Replace cover and done.

as per video

Gently pry out switch in door jam with screwdriver and pull both connectors off and put connectors on new switch then push switch back into the hole. Looked it up on the internet and video showed how to and also had link to new part, ordered and less than a week later the fridge is bright again. I have an older freezer also and it seems that they all use the same switches. Very Very easy

Unplugged the refrigerator first....then on the inside of the fridge, I popped the temp sensor cover off (upper LH side) and exposed the old sensor. I snipped off the old sensor about 3" down from the end and connected the new sensor (which I trimmed down to about 3" long) with some heat shrink wire nuts/connectors. Let the fridge run for a day or so and confirmed the problem was solved! Oh yeah, there was no way to tell the 2 wires apart (power vs. ground) on the sensor. However there was a manufacturer's stamp on the wires. So note the orientation of the text and mark one of the wires with a sharpie on both the old and new sensor before trimming. This will give you a reference for which wires to connect when adding the new sensor to the old wires.

easy pry out, disconnect wiring, connect on new switch and press in switch.

Watched a youtube on capacitors- though on a motor with a pulley, the symptoms were the same, motor running and pulley not turning-bad capacitor. Took a chance for a 17+ dollar part vs a new compressor. It worked.

There were only 3parts listed to check omed out the defrost heater and thermostat ....thermistor checked bad ordered replacement took less than 2 minutes to replace after I defrosted it again runs fine

removed the inside fridge electrical panel and swapped switches

Googled the model number of refrigerator with symptoms of "refrigerator wont run". Parts select web site appeared on my screen, opened Parts Select website, Partselect said probable cause of my frige symptom was that the run capacitor usually burns out 51% of the time. They were correct with the diagnosis 100%. I ordered the run capacitor for $23.00, installed it in 10 minutes, refrigerator runs good as new. Thank you for saving me cost of service call. I probably saved $200 or more. I will use Partselect again with my next problem. THANK YOU,
