Changing the Light Bulb in Your Whirlpool Refrigerator WRQA59CNKZ

The light bulb in your Whirlpool WRQA59CNKZ is located inside the refrigerator compartment, and you can replace it yourself in under five minutes without tools or special knowledge

The WRQA59CNKZ uses a standard 40-watt incandescent appliance bulb, which you can find at any hardware store, grocery store, or online retailer for a few dollars. The bulb sits in a socket on the interior wall of the fridge, usually toward the top or back of the compartment. Before you start, unplug the refrigerator or flip the breaker to cut power — this is a safety step that takes seconds and prevents any risk of shock.

The entire process involves locating the bulb, unscrewing it by hand, and screwing in a new one. You do not need to remove shelves or move food unless the bulb is blocked by something you have stored directly in front of it. Most owners complete this task without calling for service.

Key Takeaways

• The WRQA59CNKZ refrigerator light uses a 40-watt incandescent appliance bulb that you can buy at any hardware or grocery store.
• Always unplug the refrigerator or turn off the breaker before touching the bulb to avoid electrical shock.
• The bulb socket is located on the interior wall of the fridge compartment and unscrews by hand — no tools required.
• A new bulb should light up immediately when you plug the refrigerator back in and close the door.

Locating the bulb socket in your WRQA59CNKZ

Open the refrigerator door and look along the interior walls, usually near the top of the compartment or toward the back. On the WRQA59CNKZ, the light socket is typically mounted on the upper left or upper right wall, recessed slightly into the plastic trim. You will see a small round fixture with the bulb screwed into it. If your fridge has a light cover or lens, it may be a clear or frosted plastic piece that sits over the bulb — you do not need to remove this to change the bulb, though some owners find it easier to do so.

If you cannot see the bulb immediately, check whether anything is blocking it. Move any tall bottles, containers, or stored items that might be in front of the light. The bulb should be visible once you have a clear line of sight to the upper interior walls.

Preparing the refrigerator and removing the old bulb

Unplug the refrigerator from the wall outlet, or if it is hardwired, flip the breaker switch that controls it to the off position. Wait a few seconds to ensure power is cut. This step protects you from electrical shock and is especially important because you will be working inside the fridge with your hand near the socket.

Once power is off, reach into the fridge and gently grasp the bulb. Turn it counterclockwise — the same direction you would unscrew a regular light bulb — until it comes free from the socket. The bulb will slide out easily once it has been unscrewed. Set the old bulb aside safely so it does not roll or break.

Installing the new 40-watt appliance bulb

Take your new 40-watt incandescent appliance bulb and insert it into the empty socket. Make sure the base of the bulb is aligned with the socket opening. Turn the bulb clockwise by hand until it is snug — you should feel slight resistance, but do not force it. The bulb should be secure enough that it does not wiggle or fall out when you close the fridge door, but hand-tight is all you need.

Do not overtighten the bulb. Appliance bulbs are fragile, and excessive force can crack the glass or damage the socket. If the bulb does not seem to be seating properly, remove it and check that the socket is clean and free of debris. A small amount of dust or lint can sometimes prevent a bulb from screwing in smoothly.

Restoring power and testing the light

Plug the refrigerator back into the wall outlet, or flip the breaker switch back to the on position. Wait a moment for the refrigerator to power up. Close the refrigerator door — the interior light should turn on automatically. Open the door again and confirm that the light is working and shining brightly throughout the compartment.

If the light does not turn on, unplug the fridge again and check that the bulb is screwed in fully. Sometimes a bulb that feels snug is not quite seated all the way. Remove it, inspect the socket for any visible damage or corrosion, and try again. If the bulb still does not light after a second attempt, the socket itself may need replacement, which requires a service call.

Choosing the correct replacement bulb for your WRQA59CNKZ

The WRQA59CNKZ requires a 40-watt incandescent appliance bulb with a standard screw base. Look for packaging that says "appliance bulb" or "refrigerator bulb" — these are designed to withstand the temperature and humidity inside a fridge. Do not use a regular household light bulb, which is not rated for the cold environment and may fail prematurely or not fit the socket properly.

You can find appliance bulbs at hardware stores like Home Depot or Lowe's, at grocery stores in the light bulb aisle, or online through retailers like Amazon. The bulb typically costs between two and five dollars. Some stores sell them individually, while others package them in pairs or small sets. Keep a spare on hand so you have one ready if the bulb burns out again.

Troubleshooting if the light still does not work

If you have installed a new bulb and restored power but the light remains off, check the door switch first. The refrigerator light is controlled by a switch that activates when the door opens and deactivates when it closes. If this switch is stuck or broken, the light will not turn on even with a working bulb. You can test this by holding the door open and listening for a small click near the door frame — if you do not hear it, the switch may need replacement.

Another possibility is that the socket itself is damaged or corroded. If you see discoloration, rust, or burn marks around the socket opening, or if the bulb does not screw in smoothly, the socket may need to be replaced by a technician. This is a more involved repair than changing the bulb, but it is still a straightforward fix that does not require replacing the entire refrigerator.

Frequently Asked Questions

Can I use an LED bulb instead of an incandescent bulb in my WRQA59CNKZ?

Some LED appliance bulbs are designed to work in refrigerators, but not all. Check the bulb packaging to confirm it is rated for refrigerator use and has a standard screw base that fits your socket. LED bulbs run cooler and last longer than incandescent ones, but they cost more upfront. If you choose an LED, make sure it is labeled as an appliance or refrigerator bulb.

What wattage bulb should I use if I cannot find a 40-watt?

Stick with 40 watts if possible, as this is what the WRQA59CNKZ is designed for. A lower wattage bulb will be dimmer, while a higher wattage bulb may generate excess heat inside the fridge. If your local store is out of 40-watt appliance bulbs, order one online rather than substituting a different wattage.

Do I need to turn off the refrigerator while I change the bulb?

Yes, always unplug the fridge or flip the breaker before touching the bulb. This prevents electrical shock and is a basic safety precaution. The refrigerator will stay cold for several hours even when unplugged, so you have plenty of time to complete the task without worrying about food spoiling.

Why did my bulb burn out so quickly?

Appliance bulbs typically last one to two years with normal use. If yours burned out much sooner, the socket may be loose or corroded, causing poor electrical contact. Check that the new bulb is screwed in firmly and that the socket is clean. If bulbs continue to fail quickly, the socket or the light circuit may need professional inspection.

Is there a light bulb in the freezer compartment too?

The WRQA59CNKZ has a light in the refrigerator compartment, and some models also have a separate light in the freezer. If your freezer light is not working, it uses the same 40-watt incandescent bulb and is changed the same way. Check your model documentation or look inside the freezer to see if a light fixture is present.
