I cant find the wear abouts of the bulb on my prestige oven model CS25

Check your owner's manual.

You can download owner's manuals and installation instructions for several brands (including Amana, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.

You can download owner's manuals and installation instructions for Electrolux and Frigidaire here.

You can download GE owner's manuals and installation instructions here.

If the owner's manual doesn't cover it and there's no obvious cover on the side or rear, you'll have to remove the outer wrapper.

The light is sometimes located on the right side in the air duct attached to the magnetron or on the top of the oven cavity.

Most bulbs can be matched up at hardware stores, home improvement centers, and places like Wal-Mart or even large grocery stores.

Some use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.
