How to Install Microwave Surface Light Bulb 5304461116 in a Electrolux Microwave
Quick answer: Unplug the over-the-range microwave, let the lamp cool, remove the screw holding the light cover on the underside, swing the cover down, unscrew the burned-out bulb, thread 5304461116 in by hand, close the cover and restore power to confirm the surface light works on both settings.
The surface light bulb 5304461116 is the lamp mounted on the underside of Electrolux, Frigidaire and Kenmore over-the-range microwaves such as the EI30SM35QSA, FFMV152CLBA, FFMV154CLSA, CFMV162LBA and Kenmore 79080333310. It lights the cooktop below the microwave and, on some models, the same bulb type is used for the cavity light. This part replaces the earlier numbers 5304472447, 5304491603, 5304509452 and 5304509482. When it burns out you lose the light over the range, though the microwave keeps cooking normally.
The surface lamp is the one bulb in a microwave that the owner's manual expects you to change yourself, because it sits behind a small cover on the underside and nothing inside the cabinet has to be opened. The high-voltage warning that comes with this part applies to the cavity light on models where the bulb is behind the casing; for the surface light you never go near the capacitor. This guide walks through the cover removal, the swap and the checks that make sure the new bulb is seated and the cover seals properly.

- Unplug the microwave at the outlet in the upper cabinet, or switch off its breaker, before touching the lamp.

Tools and Parts You Need
- Phillips screwdriver
- Step stool to work comfortably under the microwave
- Paper towel or clean gloves for handling the bulb
- Flashlight
- Small dish for the cover screw
- Soft cloth to clean the lens
Step-by-Step Installation
- Cut power and cool Unplug the microwave or trip its breaker and confirm the display is dark. Wait a few minutes so the lamp and its cover are cool.
- Locate the lamp cover Look at the underside of the microwave near the front. The surface light sits behind a rectangular glass or plastic cover held by one or two screws.
- Remove the cover Remove the screw and hinge the cover down or lift it away. Keep the screw somewhere safe and wipe grease off the inside of the lens while it is off.
- Remove the old bulb Turn the burned-out bulb counterclockwise and pull it from the socket. Use a paper towel if it is stiff or if the glass is broken.
- Install 5304461116 Holding the new bulb with a paper towel, thread it clockwise into the socket until it is snug. Do not force it past the point where it stops.
- Refit the cover Swing the cover back up, align its tabs and replace the screw. Tighten only until the cover is firm.
- Restore power and test Plug the microwave in and press the surface light button. Check both the high and low settings if your model has them.
- Check the second lamp If your microwave has two surface lamps, test the other one now. They are the same age and the second usually fails soon after the first.
Fit Checks Before You Call the Job Done
- The bulb is threaded fully into the socket and does not wobble.
- The lens cover is seated flat with its screw snug.
- The light comes on at both brightness settings.
- No fingerprints on the bulb glass.
- The cover does not rattle when the exhaust fan runs.
Common Mistakes to Avoid
Handling the bulb with bare fingers Skin oil creates hot spots on the glass and the bulb fails early. Use a paper towel or gloves.
Cross-threading the bulb Forcing the bulb at an angle damages the socket. Start it straight and turn gently.
Skipping the unplug step The socket is live when the light switch is on. Always disconnect power first.
Leaving grease on the lens A greasy lens dims the light and traps heat around the bulb. Wipe it while the cover is off.
Troubleshooting After Installation
New bulb does not light The bulb is not fully threaded or the socket contact is bent. Unplug, reseat the bulb and gently lift the center contact in the socket.
Bulb burns out quickly The glass was touched or the lens was left off. Fit a clean bulb and make sure the cover seals.
Light flickers The socket contacts are dirty or loose. With power off, clean them and reseat the bulb firmly.
Only one of two lamps works The other bulb has failed too. Replace it with the same part.
Care Tips After the Repair
- Wipe the lens cover monthly along with the grease filters so light output stays bright.
- Use the low setting when you do not need full brightness to extend bulb life.
- Keep a spare bulb so a burnout does not leave the cooktop dark.

Which microwaves use bulb 5304461116?
It is listed for Electrolux, Frigidaire and Kenmore over-the-range microwaves including EI30SM35QSA, FFMV152CLBA, FFMV154CLSA, CFMV162LBA and 79080333310, and replaces 5304472447, 5304491603, 5304509452 and 5304509482.
Does the capacitor warning apply to the surface light?
No. The surface lamp is behind an external cover on the underside, so the cabinet is never opened and the capacitor is never exposed.
Can I use this bulb for the cavity light too?
On some models the same bulb serves both positions, but the cavity lamp may be behind the casing. Check your manual before attempting the cavity light.
Do I need to remove the microwave from the wall?
No. The lamp cover is accessible from below with the microwave in place.
