JMW8330DAB15 Jenn-Air Microwave Oven Combo - Instructions

Remove the screws from bottom of door to gain access to the hinge screws. Remove the bottom hinge screws and then open the door to gain access to the top hinge screws. CAUTION after removing the top screws close the door as far as possible while still griping the sides of the door. Pull up on the sides to remove the door from the stove. The springs are fully loaded if you have the door open all the way and try to lift up (like I did) the hinge will spring back and get your finger. Install the new hinge, put the door back into the oven, install all the screws and then remove the temporary rivet that comes installed in the new hinge.

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.

Shut off electricity to stove. Took out bolts, removed old element. Slide tabs out of connectors. Put new heating element in. Put bolts back in and turned electricity back on.

The door seal was an exact fit for the factory one. There are little clips that hold the seal to the door. The clips are already installed in the seal. To remove just grasp the seal at each clip and pull up. The seal comes off easily. The ends of the seal are tucked into holes at the bottom of the door so you can just pull them out. For the installation of the new seal grasp the seal at each clip and push them into the littles holes. I used a flat blade screwdriver to tuck the seal ends into the two larger holes at the door bottom. The whole process took about 10 minutes.

I wouldn't have changed the seal but the hot lasagna made the seal sort of hard after it cooled off.

Removed old assembly, attached wires to new and inserted into space for same. Of course you must turn off the range circuit breaker. The part that took the most time was removing the old assembly. Once that was done, the rest took only a few 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!

Other tools that are usefull long needle nose pliers, long thin blade screw driver and small magnetic flashlight. Place the microwave on a work bench and remove the case it cover 3 sides. Place the microwave on a chair so it can stand with the controls up. You are replacing the lower door microswitch. The switch is located behind the control panel in the lower part of the area. The switch is several inches inside this area and your hands will not fit. Take care when moving wires and a couple of sensors. Use the thin blade screwdriver to release a tab holding the switch in place. Do not break this tab. Take the needle nose pliers and remove the switch. Put the wires on the new switch, open the door a short distance so a door lever moves enough to put the microswitch back into the bracket.

Although only one side hinge had snapped, I replaced both sides with new oven door hinges. Followed the website video installation directions and all went well; the new hinges work perfectly.

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

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.

Bought a pair for needed door hinges for replacement. Found a DIY video on You Tube showing technique to replace. Door removal was a bit awkward but hinge replacement and door reinstallation was as detailed in video. Could not nor would not have tackled this project without video. Premium quality parts sent and received within days of ordering. Wife happy therefore so am I.

Access is via RT. SIDE Panel as you face microwave. There are three screws on the bottom right edge to loosen. After that the side panel slips down and off. the fuse is located in the rear near where the power cord comes in. It is the white ceramic tube 1/4" in dia. and 1-1/2" long. Pull it out like any fuse and replace with new one. Reassemble and you are done!

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.

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.
