Whirlpool Refrigerator Repair – How to Replace the Temperature Sensor (Whirlpool Part # 12002355)

both secure, we

we'd like to explain you how to change the temp sensor on a refrigerator. Its a really easy job. All we're going to need is a small flat blade screwdriver, a pair of wire strippers and crimpers, and maybe a quarter-inch nut driver.

Let me explain you how we do it. Now before we begin this repair, the first thing we'll need to do is to disconnect power to the refrigerator, so if you can pull it out far enough to unplug it or locate the electrical panels, turn off the appropriate breaker or remove the appropriate fuse. Our next step will be to remove all the items that are in the freezer, so we'll start by pulling out the drawer.

up those tabs on

With the drawer fully pulled out, well, next, slide that upper basket forward and lift it out and set it aside. Now to remove the lower drawer and the doorWe're simply going to lift up on the front. Now we'll disengage two tabs at the front of those rails and lift it off the back. We can set that whole assembly aside.

Our next step will be to remove the tracks.

Now if we pull those far enough that we can access these little locking tabsWe're just going to depress those. Then we can pull that whole rail forward. You do the same on the opposite side and then you can lift it out as an assembly.

You should keep some pressure together. Hold the rear rail and wheels up together. Now, with the drawer and the baskets removed from your refrigerator, we now have access to that temp sensor which is located in the upper right rear corner on this model.

Now there's a little plastic cover over that sensor housing and by using a flat blade screwdriver, we can go into that slotted opening or that tab back and you can lift that housing away from the evaporator cover. Then we would peel that temp sensor out of that housing, cut the harness, and then splice in a new one.

Now if you can feel that that's not enough wire or if they happen to fall back inside, you would next need to remove that evaporator cover, but firstWe'd have to take these side rails off. There are three quarter inch hex-head screws on each of those. Once we take those out, those rails will come completely out of the way and then we can remove the evaporator cover.

Just take all of those out, then we'll just set those aside. The same for the opposite side.

Now, if your model is equipped with an icemaker, you would need to remove that next as well as the wire harness connection to the back. Our next step would be to remove this rear air grill. We'll need a flat blade screwdriver. On the top outside opening on either side, there's a little plastic tab.

Just depress that towards the center.

Now you should probably have that tab back. Just lift that grill away from the back panel, both sides and then pop it off. Next, we'll remove this little cover on the temp sensor.

Just take a flat blade screwdriver, go into that opening, drive the tab back, and let it hang there.

Next, we'll remove the four quarter inch hex head screws on each corner. Now we can tilt that panel forward. We'll need to tuck that sensor up through that opening.

Now we've removed the evaporator cover to make it easier to explain you how to change this sensor.

We'll dislodge it from its housing, snap the little clips. Remove it. Then we'll cut the old sensor off close to the sensor as possible. We need to separate those leads.

You may need a utility knife to just put a little cut on the end of that. Then using our wire strippers, we'll peel back about three-eighths of an inch of insulation. Use caution that we don't cut into any of the copper wire and then just twist those strands together nice and tight.

Next, we'll take the new sensor.

We will trim off most of that wire. We don't need all of that on there, just enough that we can splice it together. Again, we'll need to make a little slice in the end.

Now that we have that sensor lead cut to a reasonable length, we'll just strip some of that insulation off.

Again, we'll press those strands of copper together. Now we'll match it up with the harness on the refrigerator, press them firmly together to make sure we have good connection. We'll take the connectors that were supplied with the kit and cramp them over those joints.

Then we can feed that sensor through the opening.

Clip it to the proper position. Now we're ready to put the evaporator cover back home. We'll start by positioning that evaporator cover towards the back.

Feed that harness with the ice maker through the opening. Then we'll just tuck this edge.

First, wind up that little arrow then snap it in. Lay the sensor over the front and just put a sleeve after the cover back until the screw holes line up, and then we'll install the screws. Now once we have all four screws secured, if our model had an ice maker in it, you can next put that on.

If notWe'd reinstall the cap over that opening.

Make sure it snaps firmly into place. Next, we'll put the outlet grill in place so it won't hold it tight up against the ceiling of the freezer, and then push the top of it in so that we engage these two hooks. That way that little tab in the center lines up in the center of the grill on the bottom row.

Next, we'll put the sensor back into position.

We'll rotate that aroundWe're going to line up those tabs on the right, fit them into the opening on the evaporator cover, and then snap it into position. Now we can put the side rails back on. Just line them up, press them into place, and then reinstall the retaining screws and do the same on the opposite side.

Once those are both secure, we can put the rails back in. If you manage to keep the two rails intact, we need to make sure that we line them both up so that the wheels turn at the same rate. If you did happen to pull one off by mistake, really all you need to do is make sure that the ribs on those wheels, there's two ribs on each of those hubs on each one of them, just make sure that they both point in the same directions when you fit it back on.

NextWe're going to set them into their opening, line them both up the same distance, and then push them back. As you push them all the way in, it will engage these plastic tabs to lock the outer portion of that rail into position, and then pull the inner portion forward to it's full extension.

it out and

Now when reinstalling the drawer front and drawer, we need to line up this little hook tab on the rear and this one on the front, and they will fit into the notch towards the back and another notch towards the front of those rails. This portion will fit down over the top of the gear, so make sure the drawer extension will pull fully out. Line up the rears, hook those in first.

Just make sure that we hook that back forcing in that slot first, then just lower the front of the drawer down until it engages itself. Check the action, make sure it pulls it in evenly and then we can install the other drawer. We put our upper basket back in.

We're now ready to reconnect the power and our repair is complete.
