Quick answer

To fix a fridge light that has gone out, check that the fridge has power, test the door switch, then replace the bulb with one that matches your fridge's base and maximum wattage. Most fridges take a small appliance bulb that screws in behind a plastic cover. Some newer models use a sealed LED module, which needs a model-specific part instead.

Free fix vs. permanent fix

Free fix · 5 minutes

Check the power and the door switch

  • Check that the fridge is running and cold
  • Press the door switch by hand and listen for a click
  • Wipe sticky residue off the switch
  • Look at the plug, the outlet and the breaker

How long it lasts: Only helps if the bulb is fine. A stuck door switch or a tripped breaker can make the light go dark while the bulb is good.

A matching appliance bulb

A dead bulb is the most common reason a fridge light goes out, and no cleaning brings it back. The right bulb for your fridge restores the light and is made to handle cold and vibration.

What to get: Appliance LED bulb for refrigerators

How long it lasts: Years, especially with an LED, which runs cooler and lasts much longer than an old incandescent.

Why it happens

1

The bulb has burned out

Fridge bulbs last a long time, but they do wear out. The filament breaks or the LED fails. This is the most common cause.

2

The door switch is stuck or dirty

A small button or plunger turns the light on when the door opens. Spills and ice can jam it, so the light stays off.

3

A loose bulb

Years of door slams and vibration can loosen a bulb a little. A snug quarter turn sometimes brings the light back.

4

No power or a special mode

If the fridge is warm, check the plug, the outlet and the breaker. A few models have a Sabbath mode that switches the interior light off, and the manual shows how to turn it off.

5

A sealed LED module has failed

Many newer fridges use a light strip or module instead of a screw-in bulb. When it fails, you replace the whole module.

Do these in order, starting with the simplest.

  1. Check the power and the mode

    Make sure the fridge is cold and humming. Check the plug, the outlet and the breaker. If your model has a Sabbath or showroom mode, check the manual and turn it off.

  2. Test the door switch

    Tool used: Dry cloth

    Open the door and press the small plunger or button on the frame by hand. It should click and spring back. Wipe off any sticky residue.

  3. Unplug the fridge and open the light cover

    Tool used: Plastic spatula or flat screwdriver

    Unplug the fridge or switch off its breaker. Many covers squeeze at the sides and slide out, and some unscrew. Pry only if the cover has a gap made for it, and never force it.

  4. Read the old bulb

    Tool used: Phone camera

    Unscrew it by turning counterclockwise. Photograph the base and read the wattage stamped on the bulb or printed on the cover. Many older fridges allow up to 40 watts, but follow what your cover or manual says.

  5. Fit the matching bulb

    Tool used: Appliance LED bulb for the fridge

    Screw it in snugly, not tight, put the cover back, plug the fridge in and open the door. If the light stays dark, the switch or the socket is the problem.

When free fixes aren't enough

Cleaning the switch does nothing for a dead bulb, so the swap is the real fix. If a new bulb stays dark, the cause is the door switch, the socket or the wiring. A switch part is usually listed by model number and is cheap, but call a technician if you are not comfortable with it. Stop and call one if you see scorch marks, melted plastic at the socket or smell something burning. Check first whether yours is a sealed LED module with no bulb. If so, order the module by model number instead.

How we picked: How we picked: this page is based on refrigerator owner manuals, appliance parts guides, and what owners report in reviews of appliance bulbs. We do not test products by hand.

Bulb or module? How to tell in 30 seconds

  • Screw-in bulb: you can see a glass bulb under the cover, and it turns out counterclockwise. Buy a bulb.
  • Sealed LED module: the cover hides a flat board or strip, with no bulb to unscrew. Buy the module listed for your model number.

The model number is on a sticker inside the fridge, often on a side wall or the ceiling.

What to skip

Regular household bulbs and extra-bright bulbs

A bulb not made for appliances can fail from cold and vibration. One that is too hot or too big can crack the plastic cover and warm your food. Stay at or under the wattage on the cover, and do not pry at the cover with force.

Frequently asked questions

What kind of bulb does a refrigerator use?
Many fridges take a small appliance bulb, often up to 40 watts, with a standard or smaller base. Others use LED strips or modules. Check the manual, the cover or the old bulb.
Is it safe to change a fridge light bulb?
Yes. Unplug the fridge or switch off its breaker first. If the old bulb was incandescent and the light was on recently, let it cool before you touch it.
Can I use an LED bulb in my fridge?
Yes, as long as the base fits, it is rated for appliance or fridge use, and its wattage is at or below the maximum. Many LED appliance bulbs are labeled for fridges and freezers.
Why does my fridge light stay on when the door is closed?
Usually the door switch is stuck or dirty. Clean it and press it by hand. A light that stays on adds heat, so fix it soon.
