How to Install Microwave Light Bulb 5304464198 in a Electrolux Microwave
Quick answer: Switch off the breaker for the built-in microwave, let the lamp cool, open the lamp access shown in your manual, pull the old bulb from its socket, push 5304464198 in without touching the glass, close the access and restore power to confirm the cavity lights when the door opens.
The light bulb 5304464198 is the cavity lamp for Electrolux and Frigidaire built-in microwaves and wall oven and microwave combination units such as the EW30MC65PSD, EW30MC65JS2, E30MC75PPSC and the Frigidaire 79049112410 and 79048913410 combos. It lights the microwave cavity so you can watch food cook. When it fails the microwave still runs, but the cavity stays dark when the door opens, which is often the first thing an owner notices on these built-in models.
Because these are built-in units, the lamp is not behind a simple cover on the underside as it is on an over-the-range microwave. Depending on the model, the lamp housing is reached from a small panel on the outer casing after the unit is pulled from its trim kit, or only after the casing is removed, which exposes the high-voltage capacitor. The manufacturer therefore recommends a technician unless your owner's manual gives a bulb procedure. This guide explains how to check which case applies, how to make the swap safely and how to confirm the new lamp is working.

- Turn off the breaker for the built-in unit and confirm the display is dark; these units are hard-wired.
- Let the old lamp cool before touching it.
- If the lamp is only reachable with the outer casing off, discharge the high-voltage capacitor first or hand the job to a technician.
- Support the microwave when sliding it out of its trim kit; it is heavy and can tip forward.
Tools and Parts You Need
- Phillips and Torx screwdrivers for the trim and access panel screws
- Paper towel or cotton gloves for the bulb
- Flashlight
- Helper to support the unit if it must slide out of the trim kit
- Insulated screwdriver and jumper lead if the casing must come off
- Padded surface to protect the cabinet front
Step-by-Step Installation
- Check the manual for lamp access Find the bulb replacement section for your model. Note whether it refers to an access panel on the casing or says to contact service, which means the casing must come off.
- Kill power and cool down Switch off the breaker and wait until the display is dark and the lamp housing is cool.
- Gain access to the lamp housing Remove the trim kit screws and ease the microwave forward enough to reach the lamp panel on the casing. If the lamp is behind the casing, remove the casing screws only after the capacitor has been discharged.
- Open the lamp housing Remove the screw on the small lamp access plate and lift it off. Note how the old bulb sits in its socket and whether the lead unplugs from the holder.
- Remove the old bulb Pull the bulb straight out of a push-in socket or turn it counterclockwise if threaded. Use a paper towel to grip the glass.
- Install 5304464198 Hold the new bulb by its base or with a paper towel and push or thread it fully into the socket. Confirm it seats firmly and does not touch the housing walls.
- Close up and reinstall Refit the access plate and its screw, slide the microwave back into the trim kit and replace the trim screws. If the casing was removed, refit it completely before restoring power.
- Restore power and test Turn the breaker on, open the door and confirm the cavity light comes on. Run the microwave briefly to check the light stays on during cooking.
Fit Checks Before You Call the Job Done
- The bulb seats fully in its socket with no wobble.
- The lamp access plate is refitted with its screw snug.
- The microwave is fully back in its trim kit with all screws in place.
- The cavity light comes on when the door opens and during cooking.
- No fingerprints on the bulb glass.
Common Mistakes to Avoid
Removing the casing without discharging the capacitor The capacitor can hold a lethal charge after the power is off. If you cannot discharge it safely, this is a technician job.
Touching the bulb glass Skin oil shortens the lamp life sharply. Handle it by the base or with a paper towel.
Sliding the unit out without support A built-in microwave is heavy and unbalanced once it clears the trim. Use a helper.
Forgetting the trim screws A microwave left loose in its trim kit can shift and pull on its wiring. Replace every screw.
Troubleshooting After Installation
New bulb does not light It is not fully seated or the lamp lead was left unplugged. Cut power, reseat the bulb and check the lead at the holder.
Bulb fails again within weeks The glass was handled with bare fingers or the access plate was left off, letting heat build up. Fit a clean bulb and close the housing.
Display dead after reinstalling The breaker was not reset or a connector was disturbed. Reset the breaker; if still dead, recheck connections with the capacitor discharged.
Light works but door does not close cleanly The unit is not fully seated in its trim kit. Loosen the trim screws, push the microwave home and retighten.
Care Tips After the Repair
- Keep the cavity ceiling and the light window clean so grease does not bake onto the lamp cover.
- Avoid running the microwave empty, which stresses all components including the lamp.
- Keep a spare 5304464198 on hand since these lamps fail without warning.

Which units use bulb 5304464198?
It is listed for Electrolux and Frigidaire built-in microwaves and wall oven combos including EW30MC65PSD, EW30MC65JS2, E30MC75PPSC, 79049112410 and 79048913410. Confirm your model number on the rating label.
Why is a technician recommended for a light bulb?
On some built-in models the lamp is only reachable with the outer casing off, which exposes the high-voltage capacitor. If your manual gives an owner procedure, you can do it yourself.
Does the bulb failing mean something else is wrong?
Usually not. The lamp is on its own low-voltage circuit and the microwave heats normally without it.
Can I fit a generic bulb?
Only if the base, size and rating match exactly. The specified 5304464198 is made for the socket and housing in these units.
