How to install interior light bulb in ge microwave oven model jvm1490sh02

Open the cover n you will see the bulb open it by turning it sideways

While replacing the cooktop light can be done by accessing the cover on the bottom of the oven, replacing the cavity light will require you to pull the oven from the wall and remove the outer cover.

The installation instructions are very handy in this case, and it's best to have two people since the microwave can be heavy and awkward.

There should be a panel covering the bulb iside the cookspace with a screw holding it on. Remove screw, cover then bulb.

how do I change the little light bulb on the top to take off the cover what do i need.

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.

On 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.

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.

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

The interior oven light can be accessed in the following way:
1.Open door and remove the top grill via the 2 screws along the top edge.
2. In the interior light will be under metal plate with fasten by single screw. The halogen bulb is rated at 120V 20watt. Looks like a G-8 bulb with 8mm pin spacing with o.a.l. 1-5/8" long

They sometimes have a plastic cover over the bulb cavity that you can take off from the oven interior

Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to 110V connectors, and that posed a real liability threat, so they stopped using them.

You now must generally remove the outer cover to replace the bulb.

In many over-the-range models, that can mean having to take the oven down from the wall! For safety's sake, that should be a two-person job and it's really helpful if you have your original installation instructions to do this.

Many models use one halogen lamp to illuminate the cooktop and another to illuminate the cavity. You must not touch them with your bare skin as the oils will shorten the bulb life.
