If you put in higher wattage bulbs than designed, your bulbs may have caused the control device (relay contacts/triac/diac) to permanently fail thus allowing the circuit to always remain energized.

On these models, the oven must be pulled from the wall mount, then the outer cover must be removed. This is apparently to limit the manufacturer's liability. Removing the microwave from the wall is really a two-person job, since it is heavy and awkward. You don't want it to fall or slip, and the edges can be sharp. It helps a lot if you saved the original installation instructions. Once the oven is out of the wall, you can then access the lamp socket. These bulbs are special halogen types that must not be touched by bare hands, since skin oils will shorten their life.

Your post has two distinct model numbers shown, so it's hard to be precise, but I'll try my best.

Always unplug a microwave before removing or installing any bulbs!
If it's an over the range type, remove the vent grille across the top and see if bulbs can be accessed there.
There may be a panel on the bottom covering the light(s), too.
If not, chances are you'll have to remove it from the wall, then remove the outer cover.
Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

That model number doesn't look quite right, but nevertheless:
If
there's no obvious removable cover over the bulb (and the owner's
manual doesn't address it) some disassembly may be required.
Always unplug a microwave before removing or installing any bulbs.
If
it's an over the range type, remove the vent grille across the top and
see if bulbs can be accessed there. There may be a panel on the bottom
covering the light(s), instead.
If not, chances are
you'll have to remove it from the wall, then remove the outer cover. If
so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.
Once it's out of the wall, the outer cover (wrapper) will need to be removed, just as you'll need to do on a counter top model.
On a counter top model, be sure it's unplugged, but otherwise ignore the instructions above this paragraph.
The
screws you need to remove should be pretty obvious, but a special
driver (such as a T20H Torx type or GTXH20-100) may be needed.
Be sure to put all the screws back in the right holes, since some may be special grounding screws.
Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.
Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.
