In this post, we will walk you through the process step-by-step on how to change light bulb in sub zero 650 fridge, so that you can change the light bulb in your fridge with confidence.

Be sure to unplug the refrigerator before starting this project. You will need a Phillips head screwdriver and a replacement light bulb. Let’s get started!

Step by Step Procedure: How to Change Light Bulb in Sub Zero 650 Fridge

Step 1: Remove Any Top-Shelf Item.

Before starting the project, it is important to clear any items off your fridge’s top-shelf. This will give you more room to work and make the process easier. It will also give you more accessibility when changing the light bulb.

Step 2: Find the Light Diffuser.

The light diffuser is located on the fridge’s ceiling, towards the back. It will be a small plastic casing that houses the light bulb.


You will need to unscrew the diffuser to get to the light bulb. But before that, locate the small, white tab on the diffuser. This tab needs to be pushed for the diffuser to come off.

Step 3: Lightly Push the Tab To the Left.

Once you have located the tab, use your finger to push it slightly to the left. You should hear a clicking noise, meaning the diffuser is now released. While doing this, be careful not to drop the diffuser.

Step 4: Pull Down the Brackets.

Now that the diffuser is released, you can pull down on the two brackets holding it in place. These brackets are located on either side of the diffuser. As you pull down on the brackets, it will be easier for you to remove the diffuser.

Step 5: Remove the Diffuser.

With the brackets pulled down, you can now remove the diffuser from the fridge. Again, be careful not to drop it as you remove it.

Set the diffuser aside somewhere safe. Make sure you do not lose the small, white tab! You will need this when it comes time to screw the diffuser back into place.

Step 6: Find and Unscrew the Light Bulb.

The light bulb is located inside the diffuser. Once you have removed the diffuser, you should be able to see the light bulb. It is important to note that the light bulb in your fridge is not a regular household light bulb.


Instead, it is a unique, Sub Zero light bulb found at most hardware stores. Once you have located the light bulb, use your Phillips head screwdriver to unscrew it from the diffuser. Be careful when doing this, as you do not want to drop and break the light bulb.

Step 7: Insert Your New Light Bulb.

Now that the old light bulb has been removed, you can insert the new light bulb into the diffuser. Again, be careful when doing this, as you do not want to drop and break the new light bulb. Once the new light bulb is in place, use your Phillips head screwdriver to screw it into the diffuser.

Step 8: Put the Diffuser Back Into Place.

Now that the new light bulb is in place, you can put the diffuser back into its rightful place. First, take the small white tab and insert it back into the diffuser. Next, line up the two brackets on either side of the diffuser and push them back into place.

Once the brackets are in place, you can screw the diffuser back into the fridge’s ceiling. Be sure not to over-tighten the screws, as this could damage the diffuser.

Step 9: Test The Light Bulb.

Now that you have successfully changed the light bulb in your fridge, it is time to test it out. First, plug your fridge back in and open the door.

The new light bulb should turn on automatically. If it does not, double-check to ensure that the diffuser is screwed in properly and that the new light bulb is screwed in properly.

Step 10: Put Everything Back Into Place.

If the light bulb works properly, you can begin putting everything back into place. Start by putting the items back onto the top shelf of the fridge. Make sure that these items are not blocking the light diffuser.


When putting items back onto the shelves, be sure not to put them too close to the light diffuser, as this could cause the light bulb to overheat and break. Once all the items are back in the fridge, close the door and enjoy your newly lit fridge!

7. If the light bulb still does not work, contact a Sub Zero service technician for assistance.
