JCB840SF2SS General Electric Range - Instructions

Unplugged from wall outlet, then opened oven front door. Reached in and removed two screws. Pulled oven sensor threw and detached electrical connector from old sensor. Plugged in new oven sensor and reversed removal procedure. No more Flashing F2 and oven temperature came to ready. Very easy.

Remove light bail, glass cover held by two nut screws. Pull socket, removed clips in back, replaced wire connectors, placed new socket in, then glass cover and bail. Wire connected in back, cover plate replaced.

Parts arrived in record time and the right parts. The detailed diagram was so helpful in finding exactly the part I needed to order. Was so easy my girlfriend with no mechanical or electrical experience completely helped me through the entire project. She secured the electrical breaker to the range, and I had the top back to the oven removed. I showed her how the little white box simply slides off the lens cover, then replaced the new one in the holes and slide it back on. Secured the back and she turned on the breaker back on...and all lights work. Thanks for making this project easy, simple and quick.

Removed 4 screws from back panel, disconnected small electricsl connector from sensor, removed one mounting screw from sensor inside oven,pulled wires through and removed old sensor. Fed wires for new sensor through and connected electrical connector, installed panel, installed mounting screw on sensor and checked oven, worked like a champ. Took 5 minutes.

Identified part and part # using schematic found on GE website, contacted PartSelect and confirmed part number, ordered and paid for part. Two days later I recieved part. Unplugged stove, removed two screws on bottom side of front panel and two on top back of same panel, pulled panel forward, pulled the control knob off, removed two small screws that hold the control switch in place, situated new control switch next to bad switch and removed one wire at the time from the bad switch and connected to the same terminal on the new switch. Put everything back together and Bingo, works like a new one. Thanks PartSelect for the friendly, personal phone service, the fast shipment and competitive pricing on my part.

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.

I took a picture of the setup and damage . I then disconnected the burnt wires and replaced the wires . Then I installed the new terminal block and connected the wires to the proper positions. The reason for the failure was that the delivery people didn't tighten the cord when they installed the stove . I would check the connections periodically as to avoid another situation like this .

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.

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.

changed sensors did not repair problem,replaced damper with mechanical damper fixed problem.

Followed the repair video, was spot on!!

I have a GE Profile French door refrig. It's only about 4 yrs old and the defroster stopped working. I read the other repair stories and was able to narrow it down to either the temp sensor, defrost timer, or main board. The refrig section was up to about 47 degrees and freezer was around 25. I could tell it was trying to cool but couldn't. So I tried the temp sensor first. I cut and spliced the new sensor on the outlet of the Evap. Coil and it took about 15 mins. Turned refrig back on and waited. The coil started to ice over after about 5 hrs I left the back panel off so I could see if and when then heater kicked on. After about 8 hrs I looked in and saw a faint glow and water trickling down and running out the drain. Turned out the sensor was bad and wasn't telling the main board it needed to defrost. I would try the sensor if you are having the same issues before spending a lot of money on the main board, defrost heater and or timer.

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.

no brainer,watched the video,worst thing was to thaw the freezer,it was realy frosted,works like new,very happy thank you.

Located temperature sensor on condenser in the freezer section( as per instructional video ). Cut off bad sensor with wire cutter then soldered on the new sensor and sealed with electrical shrink wrap.
