3865XRW Magic Chef Range - Instructions

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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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.

Removed the two screws holding the sensor to the rear oven wall. pulled out sensor wire. It was caught on other wires behind the oven. removed the three screws holding the 8" inspection plate in the center of the rear panel. Carefully move the insulation and reach in to grasp the back end of the sensor wire. Once free from the snag it easily pulls out with the sensor just as stated in the video. using the appropriate adaptor it was easy to re-asseble and and attach to the oven wall. Replace the rear panel with the three screws and it was done

Everything was straightforward other than the tabs that the screws go through before going into the back of the oven were the wrong size and the predrilled holes were not in the right location. Had to trim the metal tabs and redrill the screw holes.

I took the broiler pan out of the shipping container and put it in the oven.

Took screws out of the back on the side the sensor was on, unplugged it & took out the two screws on the inside of the oven to release the sensor. Put new sensor in place with the two screws & used one of the adapters to plug in the new sensor. Put screws back in the back panel & turned on the oven which unfortunately is still 50 degrees low. Need a new clock with computer which is out of stock & unavailable. I was an electrician for 25 years so didn't experience any problems. It was a cheap thing to try.

Turned off breakers to oven. Removed two screws that held oven in cabinet. Removed oven door by opening slightly and pulling up on door. Pulled oven out 1/3 of way. Took out four screws on top of control panel. Took oven light switch off by unscrewing holding ring. Removed temp knob on right by pulling. Removed start / stop knob same way.Removed glass straight out. Removed four screws that held elecrtonic clock conrtol board. Unpluged three wire plug from right side and the nine wire plug from the left side. Worked board out at and angle. Went backwards to connect and replace board, screws and door.Slid oven back in and tested oven after turning breakers back on, worked like new.

Removed the two screws that held the element in place and then pulled off the element from the connectors. Slipped the new connectors on. Tested the oven - Baked some blackberry cobbler!

Removed the old element by removing 2 screws and disconnecting two solderless connectors. One solderless connector was melted in two. I had to remove the rear panel and cut the old connector off and crimped on a new solderless connector. The time required was lengthened due to trip to the hardware store to get a new connector. While I was fixing the oven element my wife replaced the oven light.

Unplugged the range. Took our the oven shelves. Unscrewed the bars holding the broken bake element to the back of the oven wall. Gently pulled out the wiring to which the bake element is attached. Slipped the ends of the broken bake element off the ending on the wiring. Then slipped the ends of the new bake element over the ends on the wiring. Then pushed the wiring with attached bake element back into their position behind the oven wall and attached the bars holding the bake element to the back of the oven wall. This is really easy because it is exactly like the on-line video, for I am a 75 year old female with little technical experience.

Pulled range out from cabinet-wall to get to back side, everthing was clearly exposed tlhen. Just a matter of installing new fixture, putting back on, reconnected power source - put range back in proper place.

Unplug the 220 cord..remove rear metal back ( 7-8 Ph/screws)... disconnect the red & yellow connectors from the back of the lower element. Remove-the-lift-off Oven door. Remove the two Ph/screws (one on either end of the element) At the very rear of the oven. Install the new element and reverse the about to reassemble.

Ordered element and recieved in two days(yea). Removed back cover from unit. Removed two wire slide on wire clips. Then went inside oven cavity and removed two screws holding element intact. The element slid out. Installed element, re-installed two screws to hold element intact. Attached wire clips back on to element, re-attached back cover. Plugged unit back in and it worked perfectly. Eazy-peezy lemon squeezy.

Unplugged the range, removed screws holding the old sensor. When I pulled it out, the wire connecting to the sensor was completely broken through,therefore I could not just pull the wire to get to the connector. Unscrewed one side of back panel to access the connector. Pushed the connector and wire of the new sensor through the hole ( and behind the insulation), disconnected the old sensor and connected the new one. Re screwed the new connector in place plus rescrewed the back panel. Plugged the range in and - Viola! Everything now works like a charm and I have my oven back. Easy-Peasy. Oh - I am an older female with very limited DYI experience. I just saved myself $650.00!

Removed two screws and disconnected the element. Reconnected the new element and reinstalled the screws

First throw the breaker on the stove. Remove two screws in back of oven then slowly pull out loosen the wire attachements ......got new part in 2 days just as simple reverse the removal directions.,,,I am over 60 female and it was simple.
