Sharp Microwave R-408HS and Lite Bulb

Changing the light bulb on your Sharp carousel microwave will allow you to have needed light inside the oven. Microwaves are not designed for consumers to change the light bulb due to manufacturer liability, but it can be done. Following the proper steps will ensure a successful installation. Step 1 Unplug the Sharp carousel microwave from the electrical outlet.
Step 2 Locate the screws around the outer cover of the Sharp carousel microwave and unscrew all the screws.
Step 3 Lift off the covering.
Step 4 Locate the bulb and unscrew. Screw in your new bulb.
Step 5 Replace the cover and screw back tightly. Once done, test your new bulb.

Check out this video, it may help you. Looks like they're a common bulb.

If the unit does this the keypad area may be bad---cheaper in most cases to buy a new unit.

Looks like you just have to take off the outer cover. From the parts diagram I looked at this looks like a counter top unit. If so, unplug the unit and then remove the outer cover and then locate the lamp and replace it. Looks pretty easy to get to.

Yes definitely that should be working fine again since it only stop working when the bulb blew,so go ahead and replace the bulb so you can use it again...

Hope that helps.......

most microwave ovens built in the last 20 years do not have an
access panel to the light bulb. you must remove the screws on the back of the microwave that hold the outer sleeve in place.
Then pull upward and backward on the sleeve to disengage it
from the front lip of the chassis. the light bulb should be close to the front of the microwave behind the control panel. Some lights
are not unscrewable from the socket, but the socket and bulb
come as an assembly.

It sounds like you may have an intermittent door switch or loose door switch mount.

Does it work differently when you wiggle the door?
