This electric oven/microwave combo has an interior light bulb concealed behind/above a glass bulb cover in the ceiling of the microwave. I cannot figure out how to remove the glass cover and when trying to push it and turn it the glass cover got pushed too far and went into the interior walls of the top of the microwave. I pulled the combo from the wall far enough to see that the bulb could not be accessed from the top; the microwave must be removed first, then disassembled, to retrieve the glass cover and change the bulb.
Anyone ever removed one of these microwaves for service? Can it be removed from the front without removing the entire combo, similar to the older models? Are the number of torx screws on the face (where the door closes) all that holds the unit in? Or, will I have to remove the whole bloody thing and disassemble it in the customer's kitchen? Is there a manual explaining how to remove the microwave from the combo unit for service?
As usual, any help/suggestions are welcome...

| not 100% sure, but it looks like you will have to pull the unit out and remove the top to access the halogen light you are refering to.

Ok. I am going to pull the entire unit from the wall, set it up on a makeshift platform in front of the wall cavity and disassemble/detach the microwave from the oven, move the microwave to the kitchen counter, disassemble it, locate the light bulb and glass ampule-like cover and - change the bulb. Sort of reminds me of an old joke I used to hear in grade school, about how many people does it take to change...well, so far - three.
Any ideas on where to find a disassembly manual would help, but then any additional response at this point is helpful. thanks...again, and again, and again...

Today is the day; I have set aside three hours for this job. I have determined during the first call that simply removing the top sheet metal will not expose the light bulb "assembly", something verified by peering into the narrow, plastic vent just above the door - just a smooth expanse of desert sheet metal, and not a bulb in sight.
Thank you for your responses; of course I'll return with a prognosis in hopes of furthering our collective enlightenment and to make another donation....

For those who need to know:
The bulb can only be changed by removing the unit from the wall cavity.
Placed on an inverted wooden box, which was placed on an inverted door mat (makes it easier to "spin" the unit on the kitchen floor while still connected to power source), remove the top/back cover where the power cord goes in, remove the top cover, remove the rear/top cover(the cover on the rear of the unit nearest the top), remove the side screws holding the second, imbedded cover(the top of the air chamber), remove the screws holding the fuse assembly, unscrew the air blower and let it hang down, remove the three black screws at the front air grill, gingerly and deliberately slide the top air cover out the back - it is not easy and requires a modicum of force - note how the metal tabs are positioned as the cover is slowly pulled out. After removing a few screws near the rear left corner that would enable you to lift the final cover up enough to sqeeze your hand inside, you will, if all goes well, be able to lift up the corner.
While holding a flashlight in your mouth, hold the corner up with a little force - but not enough to permanently distort the sheet metal - and reach in with your other hand and remove the metal clip that holds the flashlight sized reflector, that surrounds the lamp base, that holds the 12volt, 5 watt halogen bulb and voila! - remove the bulb. Reassemble in reverse order. I counted 41 screws on the counter before reassembly; the customer looked bewildered when he wrote out the check, said that even though he saw how the bulb was changed by a "pro" would not do it if it went out again, but instead would call me back. I felt bad collecting the money and noted that the microwave was manufactured in Sweden.
K,man was right; it was a nightmare, but I do so much enjoy solving puzzles...thanks for the responses on this challenging issue of sheet metal technology...

OH, MY GOD!!!! I had to work on one of these Sunday. Microwave magatron cooling fan not working at all sometimes and scraping at other times.
Pulled the unit out of the wall detached top control panel sheet metal wrap to get to the two screws that come down from under the edge of top section holding side panel on and then find another panel behind that.
Didn't see how it came apart so buttoned it all back up and looked at parts breakdowns on the internet Monday and it looks like maybe with a lot more work that the next sheetmetal panel on the right side will come off and give access to the blower and right side door switches that I have to repair now since I pushed the door switch with a screwdriver and it popped back all the way and the light wouldn't turn off, then when pulled it back into position from front, now light is off, but unit thinks the door is open so now, no worky at all.
Anyone have the service manuals for these beast, that will tell the correct procedure to attack????
The one I'm working on is basically the same: Mod# KEMC308KSS0
How about it RegUS_PatOff? You seem to be able to find manuals for everything!!!

Thanks RegUS, I should be all set now......
Just got to wait for this horrible slow dial up to download them now!!!!!!
4:30am in the morning my time, going to get them started, (go to bed), and hope this crappy dialup doesn't drop me off in the middle of the morning before it finishes, (like it's done twice so far after 3hours, two times, of trying to download my AVG 8.0 virus update -- still haven't got it yet).Last edited on Wed May 14th, 2008 11:34 by Budget Appliance Repair

I just knew that microwave had to come out of there without pulling the whole oven out.
Anyone who's going to work on one of these need at least the KAC-25 manual, it shows how to access everything.
Changing the microwave lightbulb would probably only be about a 30 minute job, maybe even quicker after you've done it a couple of times.
Attached are the 3 pages, (in this and the next two post), that pretty much explains all you need to know to remove the microwave.
I haven't been back out to it yet, but should be this weekend. Will let all know how it goes. Attachment: RemovingMicrowavePg1.JPG (Downloaded 26 times) Last edited on Sat May 17th, 2008 09:56 by Budget Appliance Repair

Hey Willie,
I just had to jump in and warn you about the AVG 8.0 anti-virus update before you download it.  This may save you some time.
You might want to forget about the AVG 8.0 update and just keep using AVG 7.5 till they stop providing for 7.5 in December. Avg 8.0 has a whole lotta stuff with it that you probably will not be happy about or want. I tried 8.0 and just had to switch back to 7.5 because of all the added security features and stuff I didn't want. It really slowed my computing down. 
Check out the following discussion from this MSN computer group about the AVG 8.0 upgrade. Link is >--->Here
It looks like that group is suggesting to switch to Aviva free Anti-virus after AVG 7.5 runs out. I'm just going to continue using AVG 7.5 till December and decide what to do then. Who knows, maybe Grisoft will realize how displeased people are with AVG 8.0 and make some changes to it by then. 
Bob

Thanks for that bit of info Bob, I was going to give it try again when I go to bed and leave the computer downloading to see if I could get it.
Now, I'm not sure I will even waste the time doing that.......

Haven't put AVG8 to test on a dialup yet, so can't tell whether the download resume function works on it... on AVG7.5 it does. Otherwise it would be a pain in the back to upgrade it on my aunt's old laptop... she won't accept a newer, more efficient computer, or get the broadband...
Otherwise, after installing AVG8 there haven't been too many hassles... most of them I can cope with, although it seems that sometimes I have to give links a good, long click for them to react... didn't happen before, but it shouldn't interfere with that phase anyway... OK, the program is large and clumsily coded, compared to good old F-StopW back in the day... the install kit fit on two floppies, upgrading took a few seconds by hand, almost never crashed, just like if it wasn't there, if you didn't notice the little blue logo in the tray.
Well, its install kit DID crash a few times, sometimes in a very embarrassing situation that added to the collection of famous last words.

I didn't like the "Safe Surf & Search" function. When you google a search, first there is a delay while AVG is checking all of googles finds then all of the links get symbols next to them saying if they're approved to click on or not and when your cursor goes over the symbol you have a pop up explaining how they've checked the link out for you. It was way too much added stuff and resource waste for me.
AVG in thier help section said you can install 8.0 without the safe search function if you installed using a command line. I tried that a few times but I couldn't get it to install that way. Maybe if you could install 8.0 without safe search it may not be too bad. I might have figure it out to try it like that again. The control center looked different. I set up the email scanner right away. I just think it probably uses a lot more resources now and gave up on it.
