JES8750AAB Jenn-Air Range - Instructions

I switched the oven sensor easily enough, but it did not remedy the problem, so we are in the process of replacing the oven since it's about 20 yrs. old.

Turned oven circuit breaker off. Removed oven racks. Removed 2 screws from old element. Pulled element out slightly disconnected wires on each end and reattached to new element. Pushed back in and reinstalled the 2 screws, reinstalled oven racks and turned circuit breaker back on. All done in about 20 minutes.

It is very easy shut off the power yo the stove at the fuse box, unscrew the two screws and pull the element out replace and screw back into place.

Spoke to your very helpful staff, who advised me that a likely problem was the oven sensor. I took a chance and ordered the part, which came promptly. Your service video for the part was most helpful in my decision to try the part. Installation was a breeze, but it was the oven controller board that had failed and not the oven sensor. That called for a service professional, who ultimately fixed the problem. Your service though, was excellent and I would highly recommend you to others.

Removed glass top from stove by taking out hex screws which secured glass top to stove frame. There are two phillips head screws inside the exhaust as well. Removed two phillips head screws which hold the burner switch in place. With a sharpie pen I marked the color coded wires on the faulty switch. Removed wires from the faulty switch. Replaced new switch using the old switch as a guide to insure that wires were connected properly. Secured new switch and glass burner top reversing above procedure. Problem solved. Note: The white dot on the control knob did not line up properly with the off position. Black out white dot and make a new one in the proper spot on the knob.

Raised the unit and blocked it with 2 boards. TURN OFF THE POWER IF YOU WANT TO COMPLETE THIS REPAIR. Removed the philip head screws for removal of glass top. Remove the corner screws on switch end. Remove screws holding the switch. Remove screws holing the bracket for all switches. Lift and roll gently to get at wiring. Follow the directions for moving wires from old switch to new switch. MOVING WIRES IS THE MOST IMPORTANT STEP. Reverse your procedure to put back together and when finished remember to turn on the power.

Watch the video. Spot on instructions. Easy peasy.

Door was removed very easily. Outside trim pieces were removed. The rest came apart like a simple puzzle. Inside glass is very easily accessed. Upon assembling, time was well under an hour. Shipping was fantastic and I saved close to 200dollars between a service call and a repair.

Oven sensor replacement was easy. Thermistor was installed in less than 15 minutes. After installation STILL had "F3" error message. Harness was ok, "Clock" or ECU needed to be replaced. "Computer" is obsolete, no spares available, some companies will rebuilt for $400+. Since the stove was going to the landfill I had nothing to lose by taking the "Clock" apart. It has one chip that is probably the power supply and control chip, another chip is an EEPROM with 128 bytes of storage and the last is a darlington chip that controls the relays. Cleaned up everything that looked like it needed cleaning with alcohol. When I reassembled the unit the pins for the thermistor harness felt loose, so I took it apart, again, and found cold solder joints on all four pins. It must have been there all along but plugging and unplugging the harness finally broke out the solder so I could see it. Soldered the pins back in and now it all works. It's worth a try if you're getting the "F3" message. If the relays on your stove aren't working it would be a good idea to replace the darlington chip. Good luck.

Trial and error and reading and rereading the instructions.The use of the jumper wire was not detailed enough. Caller a repair man.

My cook top has the red wire piggybacked along all the cook top switches. It was easy enough to reroute the red wire coming from the dual surface burner to pin 4 i believe on the new switch. Follow the previous thread and look at the instruction sheet online for this switch

-Disconnected power from oven at the circuit breaker.
-Removed oven door and racks.
-Removed two screws holding element to the rear wall.
-Carefully pulled element away from rear wall, exposing wire leads.
-Carefully detached wire leads with male Sta-Kon connectors from element ends. (Taking care not to break or weaken the wires at the connector.)
-Disposed of old element and placed new element in same position.
-Re-attached leads by very carefully sliding male Sta-Kon connectors into the new element connectors, taking care not to push too hard and bend element wire.
-Gently re-inserted element ends into wall and re-attached element to wall with original screws.
-Reconnected power and tested new element. Element did not heat.
-Disconnected power and looked for collateral damage from original element failure.
-Removed oven from wall, removed rear panel and identified the high-temperature limit switch.
-Removed Sta-Kon leads and checked switch for electrical continuity. It had none, apparently the result of the high current from original element short.
-Obtained new hi-limit switch from Part Select
-Removed and replaced hi-limit switch, re-attached leads.
-Replaced rear panel and reinserted oven in wall.
-Reconnected power and tested new element. Element heated normally.
-Returned racks to oven, re-attached door and done.
