3962VVV Magic Chef Microwave Oven Combo - Instructions

replaced Hi-Limit button by removing rear oven cover. Changing by removing screws than replacing with new button.................................. changed sensor by removing screws inside oven and replcing with new unit. changed connector behind rear cover.

Removed the single phillips screw that held each plastic slide guide to the stove, and replaced the part reusing the screws. Was so simple I didn't even have to swear. This was my mother-in-law's stove, and she was so happy to have it repaired she's fed me twice since.

The video indicating •unscrew old sensor, •pull wiring, •unplug old sensor, and •plug in replacement was good until I pulled the old one and saw wire nuts behind the small square hole! After some research, I learned that the nuts COULD come through that small hole with use of needle nose pliers. One of the wire nuts had the edges pinched off (chipped) in the process. Then I learned about ceramic wire nuts, which I'd never previously encountered. Very important if you don't want to melt your nuts! I cut and stripped the end of a disconnect plug to the stove wiring and now I have a plug in place; which, hopefully, I'll never need to use.

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.

Remove screw securing the broken drawer guide. Placed new drawer support in place and tightened screw. Replaced drawer. All done in less than 5 minutes (and cheaply).

I noticed the drawer on the broiler was sliding crooked and found the plastic slides had broken. Of course I thought it would be a hassle and not worth the time to fix it. I would just "live with it". Boy was I wrong, it was probably the simplest fix ever. It was easy to get the correct parts from PartSelect with their exploded and concise diagram. The parts were ordered and delivered in a couple of days. It took me all of 10 minutes with a screwdriver to make the repairs. Now it is a good as new.

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!!

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.

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 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.

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 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.

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.
