My microwave works just fine, but the inside light bulb is not working. I can not figure out where it is located to change it, or what kind of light blub I have to get to change it. Any help will be greatly appreciated.

Take one fluorescent light-bulb -- not connected to anything -- and a darkened room. Start the microwave, and see if any emissions from it activate any of the fluorescent materials inside the light-bulb.
I would say you have blown a fuse on the unit. As you now have found out, that's one of the reasons why you unplug any electrical equipment before working on them. You will have to take the outer cover off the microwave and locate where the fuse is. It is most likely on the back of the main PCB or possibly inside a plastic sleeve or mounting near where the cord enters the unit.
1 Unplug the microwave oven from the outlet. Wait 20 minutes for the capacitor that is inside the microwave to discharge. 2 Unscrew all the screws around the casing by turning them counterclockwise. 3 Remove the cover by lifting off. 4 Locate the light bulb in the microwave. This will be located on either the right or left side. 5 Unscrew the light bulb by unscrewing counterclockwise. Some light bulbs are held into the socket by two notches; for these you will need to gently push on the bulb and turn counterclockwise to remove the bulb, then pull out of the socket. 6 Place your new bulb in the empty socket and secure by turning clockwise until tight, or if the bulb is one with notches on both sides, then guide the notches into the slot on the socket, push gently and turn clockwise until clicked into position. 7 Replace the cover and screw back on. You are now done and may plug back in the microwave.
The part that controls that is goes through your control panel on your microwave. For the lights to come on to start with the door being closed switches have to be working right and when you press start the lights come one. When the microwave is through cooking and you open then close the door then the lights should go out. The logic IC on the control panel board that detects all these events is not being reset correctly. Unless you get a microwave tech to track down the component on the control panel circuit board it is not something that you could do on your own since it takes voltage and signal checks with the proper equipment and then some soldering and desoldering of the defective component(s). Good luck and God bless.
If you are comfortable with taking the cover off, Unplug the microwave, usually there are 2 philips screws on the top back, 2 on the right back and 2 on the left back edge cover. Sometimes, their might be a screw on the bottom but you will notice this right away if there are or not if the cover doesnt come off.
Then located the light bulb. You should be able to see the opening from inside the microwave where the light bulb is located.
Once you locate the bulb, then there are usually 2 types, type 1 screws in and the other type is a bayonet type, which you push down, and then twist. You should be able to figure this out.
Sometimes there is a plastic cover that is placed around the bulb to kinda help focus the light towards the inside of the microwave.
Once the bulb is out, then take it to your local hardware store and see if they can match it up. You might want to call first to see if they carry them before driving all over the place.
Hope this helps.

Unscrew the vent at the top of the microwave(2 phillips head screws) inside to the right you'll see another screw holding a metal panel. Unscrew this and take the panel off and you'll see the bulb, which will unscrew counter-clockwise
