CES3759BCS Magic Chef Range - Instructions

took the old one out (two phillips head screws)and put the new one in. done. took about 5-6 minutes.

unplugged oven. removed 2 screws that hold the sensor in place, then removed the dozen or so screws that hold on the rear panel, unplugged sensor and fed wire through insulation. identified and installed correct harness adapter then fed new wire and connecter through insulation and connected to adapter. installed sensor retaining screws.plugged oven back in and tested function.no dice. unplugged oven once again. removed oven control panel and upon inspection of printed circuit board discovered 3 solder joints had failed. dang. resoldered failed joints and also sweetened up a few others that looked suspect. reinstalled controller, replaced all retaining hardware, and plugged in the oven. tah-dah!! works like a charm now. moral of the story is check the pc board first and save $50 for unneeded pats!!! or buy the controller from parts direct for $260ish. btw a roll of solder and soldering iron from an auto parts store cost around $10, learned to solder on you-tube $0. amazing all the home appliances yo can fix if you're not afraid to take a few screws out and poke around a bit. CHEERS!

unplug and plug in new

replacement was very easy, took 5 min

swap a known good coil around and still did not work. then measured voltage across the switch terminals and found out one leg was opened. Ordered a new switch which looked alike. The new switch could handle more current than the old one. Turned out that all terminals of the new switch were same size while the old one had 1 smaller size. Used the dremer tool to file it to fit the wire terminal. Also the burner knob had different grove type . Just forced it in.

The entire "project" took me less than 3 minutes, and required no tools at all! First, the saleswoman over the phone pointed me to the correct product for my problem ($30 less than what I thought I needed), and it arrived at my home within 4 days. Then, it was just a matter of pulling off the old gasket, and snapping the new one in place! Simple!

Remove 6 screws fastening element to top of oven. Remove most of the screws from the back and pull away from oven. Use pliers and pull wires off of element connectors.Remove 2 screws fastening element to rear of oven. Install new element with fastening screws. Re-Install wires and fasten back of oven. Re-install the six screws to fasten element to top of oven.

Removed front panel of range, removed switch (2 screws), unclipped wires from back of existing switch. Installed new switch - reverse order of above.

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.

• Removed the oven door (pulled right off old hinges)
• Removed two screws
• Removed broken hinge
• Placed new hinge in place
• Replaced screws
• Replaced oven door.

The sensor is mounted in the top right side of the oven.An extra long screw driver helps to avoid damage to the sensor when replacing it.The connectors were the opposite to the old sensor and I did not see that there were adapter cables included. It might help to connect or tie these together as I only expected the sensor and did not look for adapters.I had cut the wires and used wire nuts when I found the adapters.The repairs works fine.

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

Watch the video. Spot on instructions. Easy peasy.

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.
