38FB-42TXW 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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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.

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.

The ignitor heated up and the broiler worked but not the bake mode. Repaired per instructions

Removed all the racks from inside the oven, unscrewed the 6 screws that held it into the cabinet, pulled it out and sat it on the floor in front of the cabinet. Removed the oven sensor from the inside of the oven after disconnecting the wire harness from the rear right exterior of the oven. Installed new sensor from inside (2screws), plugged it into the harness in the back and reinstalled oven in the cabinet.

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.

Unplugged the old temp sensor at the back of the stove. From the inside I removed the 2 retaining screws. I taped a string to the old wire and pulled it through so I could pull the new harness through on the new sensor. When the new sensor arrived I installed it in reverse order. Easy peasy. Works great!!!!

Lift burners out of plug discard old drip pans replace new drip pans into plugs and done .

I just removed the lamp retainer plate and glass cover, inserted the new gasket, and screwed everything back in place. Simple as that. I was enormously pleased that the part arrived so quickly -- just in time for me to cook my Thanksgiving turkey and use the self-cleaning feature.

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!

Extremely simple repair to make. Move stove away from wall and disconnect power. Remove the oven racks. Remove the rear sheet metal panel covering the wiring harnesses. Caution: Sharp edges and corners on sheet metal.Sensor is located in upper left corner on rear oven wall. Using a long-shafted #2 Philips screwdriver, remove the two Philips head screws and gently pull the sensor 1" away from the oven wall. At this point, it will help to have an assist from someone while you are behind the range. Have the assistant gently tug on the sensor while you watch for wires moving on the rear of the range. After locating the sensor wires, gently disconnect the plastic connector clip. Note: plastic connectors become brittle with age and exposure to heat Move to front of range and gently remove sensor from rear wall by pulling the wiring through the oven wall. Before inserting the new sensor wire through the oven wall, "dry fit" the wiring connectors to see that the new sensor is a correct connection. Make connection, and secure the sensor to the rear oven wall with the two screws. Install racks, reinstall rear sheet metal panel, and connect the power. Set the oven baking temperature to a moderately low temp, 300 - 350 deg. to test the new sensor.

I removed the two mounting screws and pulled the harness through the opening unsnapped the sensor from the harness and installed the new sensor i didn't have to used the adapters the new sensor fitted

No problem Took off old ones and replaced with new.

Remove rear sheet metal cover. Disconnect the temp sensor wiring connector (on the left side as viewed from front).

Open oven, take out the 2 screws attaching sensor and remove. Reverse for installation.

Included wiring adapters are not needed for this model oven.

Took the old ones out and put in the new ones! What I am so pleased about it that I just went online and at Parts Select website it was easy to find what I needed, a fair price and the 4 bowls arrived within 2 days!
