Need to change the bulb in microwave kemc308kss

It seems to be self cleaning... burning all the oils that coats the inside from microwaving food that wasn't covered. Clean the oven well and to remove bad smells put lemon juice in a bowl and microwave.

Found this post on another fixya-type site: below is the link..
Here's a repeat of Kai's instructions so you don't have to scroll down. I just replaced mine and it was a snap. Just a few Phillips screws and a few tugs. No need to pull the unit completely out as you can access the bulb after it's about half way. No need to disconnect any wiring harness except pulling the bulb out of its socket. I used the 10w (G4 12V) replacement bulb from Home Depot at $6. The light is a bit brighter but there've been no problems with fuses.

1) Turn off power to the unit
2) Open the lower oven door
3) Remove the side trim screws and pull the trims down and out.
4) Remove 2 screws on the sides of the control panel.
5) Open the Microwave door. Remove the 3 screws on the Air Vent Plastic Cover on top of the microwave. You can then remove the Air Vent Cover by pushing the control panel up and pull out slightly at the bottom.
6) Remove the 4 screws on the Air Vent Plastic Cover on top of the lower oven and remove the Air Vent Cover. (You may have to remove the left under side bracket of the Microwave door temporarily just for the Air Vent Cover to clear the screw of the bracket. Re-secure the side bracket of the Microwave door panel as the front panel may fall)
7) Remove the 2 screws which held the Microwave unit in place behind the Air Vent Cover on step 6.
8) Wiggle the Microwave unit out about half way to expose the light bulb unit on top center
9) Wiring to the Control Panel will prevent you from pulling the Microwave unit out any further. And you don't want to do that as the unit may fall. Space is cramped, but working carefully with pliers you should be able to release the springs which held down the light bulb unit and change the bulb.

I have a kems308...very similar to yours. Order the bulb by finding it on the parts list and ordering it on Amazon or thru Kaid. Mine was $13.00! The bulb on mine is a baseless bulb that goes in a bulb holder held by a spring behind the control panel. The control panel is easy to remove, but turn off the power first. Plan on an hour. If you can access yours this way it saves having to remove the whole unit.

microwave light is burned out. Need a replacement. What part # is it and can I order it online?

Call the Electric Company.

To change a control board, do I need to take the door out?

KitchenAid wants $58 for the replacement bulb. I bought it for $1.99 from www.lightbulbsdirect.com and it works just fine. The Item number is Q5G412V. It is a halogen 5-watt, 12-volt bipen G-4. Replacing the bulb requires some dismantling of the microwave. At first I was nervous about removing so many parts to get to the bulb but in the end it really wasn't so bad. The only tool I needed was a Phillips screwdriver. I surfed the net a eventually found instructions left by a friendly Blogger that guided me through the whole process. KitchenAid engineers were so STUPID when they designed this microwave. It takes two hours to replace a bulb that should take 5 minutes. Oddly enough, replacing the bulb in the normal oven below the microwave oven is a piece of cake.

not a problem, first you can refer to your user manual as to how to remove door, (pg 21) heres a link if you misplaced it.

then Ill include this link as well, which is apart breakdown for your GENERAL oven, and i do this so you can see the different panes of glass( ther are 4 of them inthe oven door, each one different so ordering hte right one will be half the battle. http://shared.whirlpoolcorp.com/assets/pdfs/literature/Repair%20Part%20List%20-%208186032.pdf
the numbers after you model example, kemc308kss** (01,02,03,04) these last 2 digits will also determine which glass you actually have

Once the door is off and you have the correct glass, changing the glass is nothing more then reomving screws from the door frame, layer by layer until you get to the broken pane, not real difficult at all

yes you wilkl need to remov ethe micro from the oven mountingin order to access the light bulb (dumb-design) but no way around it

there is two fuses a 15 amp and a 20 amp fuse on the left hand side of the microwave one or both have blown
