How do I replace the microwave light bulb ?
For model number JT3800DH7BB
Hello Donald, thank you for getting in touch. Slide a flat blade screwdriver between the housing and the glass light cover. Support the glass light cover with two fingers to prevent the cover from falling to the bottom of the oven. Be careful not to chip the oven coating. Gently twist the screwdriver blade to loosen the glass light cover. Remove the glass light cover. Remove the bulb by firmly grasping and sliding the bulb straight out until the two prongs have cleared the ceramic holder. Do not touch the glass of the new replacement bulb with your fingers. It will cause the bulb to fail when it lights. Grasp the replacement bulb with a clean towel or facial tissue with the prongs facing down. Align the two prongs in the ceramic holder, pressing gently until the bulb is securely in the ceramic socket. Slide the protective lens into the holder and push until the clips snap into the housing. We hope this helps.
Turned out the issue was easily solved by replacing a single, inexpensive fuse.
First off, UNPLUG THE MICROWAVE.
The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the mic
... Read morerowave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.
Remove microwave outer cover. Turn on side & locate the upper & lower door switches. Better to replace in pairs even if one is ok. Remove the wire harness to each switch. Then replace switch and re connect the wire harness. Re attach outer cover and test to see if that solved the problem. If so then well done!!
