3865XRA 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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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.

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.

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.

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.

Got a bent metal coathook to temporarily release the oven door, removed the screws from the old probe, inserted the new one, and hooked it up, using the one of the plug adapters provided. Problem solved! The oven door latch was now disengaged, the oven would now accept temperature inputs, and the rear cooling fan (which wouldn't shut off) now turned off. That's a lot of things working better for less than $50!

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

Very simple fix--unpugged two fittings in the back of oven plugged in the new element and it was done.The Best part was that the element burned out on a Sunday and I ordered the part that day and it shipped on Monday and received part on Wed AM.This is the second time I've had to replace the element and by ordering through Part Select I saved $24.00 versus buying it from an appliance store.

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!

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.

I had to pull out the oven and balance the oven on two patio tables. Remove the back of the oven. Pull out the light assembly which was burnt. I was unable to remove the casing around the light, so I destroyed it with a pliers. Reinstalling the new light and assembly was easy. What made this job difficult, I could not remove the light assembly from the front of the oven and had to go in from the back.

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.

Removed the failed bake element per the video linked in the Partselect email. Unlike the video on YouTube the PartSelect video shows that the bake element can easily be replaced through the oven door and it is not necessary to slide the range out and remove a rear panel.

Removed screws of old element pulled clips off replaced with new element very easy
