3968VVV Magic Chef Microwave Oven Combo - Instructions

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!

First I called a repairman and left a message. That was 3 weeks ago. So, I 'googled' the error message and determined what part I thought I needed. Ordered the part on Wednesday evening and it was there when I got home from work on Friday. I unpacked the part, got a phillips screwdriver and then watched the repair video on your website. About 20 minutes later I pushed my stove back in place and the flashing said 'set time'. Then I checked both ovens, and have since used both, and everything works!!

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

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 old Element-B by removing 4 screws and inserted new
element. Took less than 5 minutes. It's as good as new now.
I thought I needed a new range but my son-in-law suggested I
go online and check if part is still availabe. It was and the rest is history. Thank you PartSelect.

Removed the ice brucket,
Removed the light shield by releasing one screw using a nutdriver.
Replacing the bulb and reinstalled the light shield.

Your web site is one of the best and most helpfull service sites I ever used. Just wish that in the future you will ship parts overseas.

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

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.

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.

simply took off smooth surface top flipped it upsde down on a towel. unbolted the entire burner assembly. matched connections with the new burner with limit switch. replaced smooth surface top plugged it in. no problems. extremely easy fix no repair charges.

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

Replaced the thermostat according to existing videos and had to adjust the thermostat using instuctions in the user manual for model CWE4800ACB.
