– Hey, it's Ryan with Appliance Repair and today I'm going to show you how to replace the freezer defrost sensor on the Samsung refrigerator. We'll need a few different tools for the job. We'll leave those listed in the description below.
Let's get started. For this repair, unplug or disconnect power to the refrigerator. The first thing that you'll need to do is open up the freezer drawer. Next, remove the upper freezer tray assembly by pushing it to the rear, lifting the wheels out of the slots, and then lifting up on the front to remove it. Next, remove the freezer box tray by tilting the rear and pushing back to remove it from the front slot.
Then tilt forward and lift up to remove. Next, remove the four 10 millimeter bolts. There are two on each side. Next, we can remove the freezer door by grabbing both sides, lifting up to remove the door brackets from the slide rails, and lifting out to remove.
Next, remove the retaining pin from the gear shaft by simply pulling it out. Next, remove the gear shaft by sliding it to the right, then lifting up on the left side and sliding it out to remove it. Next, remove these two Phillips screws. (drill whirring) Before removing the panel, it's a good idea to let it thaw out in case the panel's frozen in place.
You do not want to use any additional heat sources, as it can warp the inside of the freezer. Grab the bottom of the panel, pull towards you, then pull down. Be careful as the top is still connected by wires.
Now, disconnect the electrical plug by depressing the locking clip and pulling out. Now, rotate the top of the panel downward to remove it from the freezer. With the evaporator cover removed, we'll now need to remove the electrical cover to give us access to the wires. Squeeze the sides of the cover and pivot it to the side to remove it.
There are three separate electrical plugs. You'll need to depress each of the locking clips to remove the plugs. With the electrical plugs removed, we'll now need to separate them by prying and removing the retaining clips. Now, cut the zip tie. Next, remove the sensor and holder by pulling it off the evaporator coil.
Now, remove the sensor from the holder. If you have a bad defrost sensor, and you need to purchase a new one, you can check out our website, PartsDr.com. We'll leave a link in the description below. You want to make sure that you're searching with the model number from the tag on the refrigerator to make sure that you get the correct part.
You can also check out our other article that shows how to test the defrost sensor. To install the defrost sensor, first put the sensor into the holder, then attach it to the evaporator coil. Next, install the three electrical plugs back onto the retaining clips. Next, plug it back into the wall.
Make sure all three plugs snap into place. Next, zip tie the wires back together. Now, reinstall the electrical cover by tucking in the wires and pushing it until it snaps in place. To reinstall the cover, push it to the rear, then rotate it up and set it on the slide rails.
Now, reconnect the electrical plug. Now, insert the top of the cover into the slot in the ceiling. Then push the bottom parts until they snap into place. Then, reinstall the two Phillips screws.
Next, fully extend the freezer drawer slide rails. Take the end of the gear shaft with the hole in it and insert it into the right side. Then, align and insert the left side. Now, reinstall the retaining pin. Next, reinstall the freezer door by aligning the tabs on the door brackets with the slots on the freezer glides and setting in place.
Now, reinstall the four 10 millimeter bolts. Next, reinstall the freezer box tray by inserting the back first, tilting the front forward into the slot, and then setting it in place. Next, reinstall the upper freezer tray by tilting in the rear and setting it down onto the freezer box tray. Now, push it to the rear and then pull it forward to make sure the wheels are locked in place. So that's it for this repair.
