Has your Samsung refrigerator’s interior lights stopped turning on when you open the doors? Or maybe the ice/water dispenser has stopped working? The refrigerator’s door switch likely needs replacing, as it is likely causing these issues.

Gather materials

Before starting this repair project, you’ll want to ensure you have all the necessary replacement parts and tools on hand. Here’s what you’ll need:

• New Samsung door switch (DA34-00066C) – If you don’t already have the new door switch, you can pick one up online from AppliancePartsPros.com.  Make sure to verify it is specifically for your model before purchasing
• Small flathead screwdriver – This is needed to pry off covers and disconnect the door switch wire harness. Opt for a high-quality screwdriver that will prevent stripping screw heads.
• Phillips head screwdriver – Required for removing screws from the metal switch cover plate. Again, select a sturdy, well-made screwdriver.

Once you’ve gathered both the new door switch and necessary screwdrivers, you’ll be ready to tackle this repair job.

Remove covers

With your supplies in hand, you can start the door switch replacement process by removing some covers to access the part. Here are the steps:

1. Open both the refrigerator and freezer doors to expose the bottom trim area.
2. Use the flathead screwdriver to carefully pry off the two small plastic trim covers on the bottom corners of the French doors. There will be one on each side. Set them aside safely.
3. On the top of the refrigerator, locate the larger metal switch cover plate. Use the Phillips head screwdriver to remove the two screws holding this cover in place.
4. Lift up the metal cover plate and gently pull it straight off the refrigerator. Set it aside.
5. Beneath the cover plate is a smaller plastic cover fitted directly over the door switch itself. This has a locking tab that you’ll need to detach with the flathead screwdriver.
6. Once released, slide the plastic switch cover downward and off the door switch. Set this small cover off to the side with the other removed components.

Once you complete these steps, you will expose and prepare the door switch for replacement.

Remove the old door switch

With the switch uncovered, you can now detach the old malfunctioning component from the refrigerator. Here’s how:

1. Disconnect the wire harness from the old door switch. You should be able to easily unplug it by hand.
2. Use the flathead screwdriver to detach a rubber cover fitted around the switch. Carefully pull this off.
3. Beneath the rubber cover are plastic locking tabs on either side of the switch. Use the flathead screwdriver to depress these tabs one at a time.
4. As you release each locking tab, the switch will detach from the inner panel of the refrigerator.
5. Once both tabs are released, slide the old door switch out and remove it from the refrigerator.

Be sure to take note of the way the old switch was installed before fully removing it. This will make installing the new replacement part easier.

Install a new door switch

With the old faulty door switch removed, it’s time to install the new Samsung replacement part. Follow these instructions:

1. Hold the new door switch in the same orientation as the old one.
2. Insert the new switch into the door switch bracket the same way you removed the original.
3. Push it straight in until both plastic locking tabs snap into place. Ensure the switch is mounted flush.
4. Place the rubber cover back over the new switch, taking care to fully seat it.
5. Reconnect the wire harness to the door switch terminals. You can only connect it in one way.

Installing the new switch is quick and easy. Just be sure to orient it correctly and make sure all connections are snug.

Replace covers

Once the new door switch is mounted to the refrigerator, you can put all the covers back on:

1. Place the metal switch plate cover over the door switch area. Line up the holes with the screw anchors.
2. Insert and tighten the two Phillips head screws to secure the metal cover.
3. On the bottom of the fridge, snap the two small plastic trim covers back into the corners. The arrow indicators should point downward.
4. Press firmly on each cover corner to ensure they are fully seated and locked into position.

Replacing all the switch covers completes the door switch installation.

Test refrigerator

With the new Samsung door switch installed, the final step is testing it:

1. Carefully plug the refrigerator’s power cord back into the outlet.
2. Close both the fridge and freezer doors completely.
3. Open each door and check that the interior lights turn on immediately.
4. Ensure the ice/water dispenser is operational.
5. Listen and feel around the doors to make sure there are no air leaks.
6. Let the refrigerator run for at least 15 minutes and check that temperatures are cooling properly.

If the new door switch is working correctly, your Samsung refrigerator should now be back to keeping your food cold and ice/water flowing! The lights turning on reliably and any other issues related to the faulty switch should be resolved.
