JCB840SF2SS General Electric Range - Instructions

I went to a GE repair center to explain my problem, the service center reccomended that I have a techinician come out o look at it. $75.00 for the visit and what ever labor and materials wuld cost.

I went on line to see if there were others having this same problem and found that there were many with the same problem.

After reading some of the ways that people found out what was wrong ...it became a matter of three components, the timer, heater or thermostat.

I tried the most common component and the less expensive one first , the thermostat switch I installed it very easily snipping two wires and attaching the news using wire nuts I used the diagram on this website to pinpoint the component and there has not been a problem since.

I removed the old temperature sensor by cutting the wires. I attached the wires of the new sensor with wire nuts and mounted it in the same bracket.

Removed six 1/4" hex nuts on rear of oven. Then through front/inside removed a single 1/4" hex nut to actually remove sensor. Unplug sensor connector, remove. Reversed steps, push oven back in place and plugged in. Tested oven function.

went to your website and viewed exploded view to find the sensor( there are two I just picked one to replace for now), pried the cover off carfully and pulled out the sensor. I snipped the wire in the middle leaving plenty to work with. I shortened the wire on the new piece, spliced the wires together and with some 3M rubberized, tape wrapped them up, replaced the sensor back into the cover and snapped in place.

The existing terminal block on my Ge oven/Range had melted due to a loose wire causing sparking and starting the plastic casing of the terminal block on fire and melting it, Part select made the part easy to find and had it at my house in 2 days. All I had to do was remove six screws to take the back sheet metal cover off of the oven. Unscrew the terminal connections remove two mounting screws that held the terminal on to the oven body. This was a little trickier than it should have been because the melted plastic had reformed making it very hard to access the mounting screws. i then mounted the new piece and plugged the oven in, it took 15 minutes and was very easy. definitely saved me at-least a $100 for the service call i would have made if finding the part wasn't so convenient

put fridge into test mode, failed One sensor. Took it out, Tested it, Ordered part also picked up splice kit from electric store spliced it truned on and good to go

I started by Unscrewing the range top. 2 small screws. I took off the old piece by unclipping the piece . Then I color coded each wire so that I would know exactly where I would place the wires for the new part. 30 min maximum time spent changing the part. Please don't forget to unplug the range before you start.

Unplugged appliance and removed 5 screws on back of stove/oven and removed plate. Disconnected the sensor and unscrewed it on the inside of the oven. Pulled the cord through and replaced with new sensor. Replaced all parts and plugged in the appliance and tested. Worked great.

Took panel off back of inside of freezer section, took off old sensor from the evaporator, spliced new sensor into the existing wires, waterproofed spliced connections, snapped sensor back onto evaporator, then put panel back on the inside of the freezer. Really, it took only 10 minutes to fix. Now refrigerator defrosts like it used to, and temps have settled in at specified temps.

Noticed the problem in November 2009. Replaced Hi Limit Sesor for Defrost thinking it was the freezor temperature sensor. Did not fix the problem. Replaced Motherboard. Did not fix the problem. Called Sears Repair. They mis-diagnosed the problem and told me it was the sealed system. I doubted them and sent them home. Replaced the correct freezer temperature sensor that connects to the motherboard. FIXED.
Removed a panel, cut two wires, soldered and insulated two wries, reinstalled panel.

Slide range out. Remove screws holding back vent in place. Remove back vent. Remove screws under front panel and knobs. Lift glass cooktop. Remove screws holding switch in place (behind knob) unplug each wire from switch and immediately replace in same spots on new switch. Replace everything.

1) pull out the stove
2) remove the 7 sheet metal screws holding the back panel on. (the panel that also covers where the cord splits and connects to the oven.
3) Find the small plastic connector located in the middle of the back of the range and unplug it.
4) open the front of the oven and remove the one screw holding in the oven temp sensor.
5) replace the sensor and make sure to "feed" the new cord through as best you can.
6) I had to dig through the insulation a little bit to find the new wiring harness
7) connect the wiring harness and put the back of the range back on

note: this was very simple to do if you think this might be the problem don't hesitate to handle this one yourself.

No self defrost. Measured heater coil with ohm meter which was OK (not open). Ordered 2 temp sensors (there are 2 in freezer, 2 in fresh food sections). The original and the new all meaured ~150 ohms. Replaced one by one. This did not fix problem. Ordered defrost thermostat. Original measured ~150 ohms - new one was ~100 ohms. Unpluged refridgerator. Removed coil panel (4 nut screws) in freezer and light cover (1 small phillips screw). Locate defrost thermostat clipped to top of coils (orange / pink wires). Cut wires and unclipped thermostat. Stripped insulation off of wires and reconnect using wire nuts. Clipped thermostat back to coils. Ran refridgerator without panel on coils to see if coils frosted up again and listend for fans/compressor to stop ( took hours). Opened freezer and viewed glow of defrost heater. Problem resolved.

Replaced temperature sensor in the oven first ($10 part, always start with least expensive possibility!), but that didn't solve the problem. 5-10 minute repair, not counting moving the range in and out of it's home between cabinets. Next replaced the control board ($90 part) which solved the overheating problem. 15 to 30 minute repair, don't be intimidated by all the wires. Remember to turn off power at the breaker (duh). Order the faceplate graphic ($37 part) because chances are the old one won't peel off cleanly (ours didn't, "I was really careful Honey!!) and the otherwise excellent PartSelect.com website doesn't suggest the part might be needed. Anyway, I saved a minimum of $80 plus Labor by doing it myself. I had the advantage of living about 100 miles from their warehouse and got NEXT DAY delivery from FedEx instead of 3-5 business days. Suggest you order before noon.

easily lifted the top of the stove after removing two small screws in front of the stove.removed screws holding burner in place , disconnected some wires and replaced burner. be sure to turn off the power before beginning this project
