Hi, We are professionals from Appliance Repair. Today we are going to show you how to change the bimetal thermostat on your refrigerator and it’s a really easy job. All we are going to need is a Phillips screwdriver, a 0.25 inch nut driver, a flat blade screwdriver, pair of wire strippers, roll of electrical tape and a few butt splice connectors. Let me show you how we do it.

Now to do this repair we are going to be working some electrical circuits so we suggest that you disconnect the power to the refrigerator first. The next we are going to open the freezer door and there is an ice dispenser in it. You will need to remove the ice dispenser bin and the auger motor assembly.

So we will take the bin out and set that aside. Then using a 0.25 inch nut driver we will remove the four screws in the corners of that auger motor assembly. You can take the cover away from the light bulb and remove the light bulb as well to avoid damaging it.

So press the two tabs in the side of the light cover and slide it off, and remove the bulb. Then we can lift that motor assembly and just lay it on to the lower two brackets and it will stay there. Then using a flat blade screwdriver we are going to release the locking tab on that wire harness and then disconnect the harness. Now with the harness disconnected, we can lift that complete assembly out and we will set it aside.

Next, we will remove the racks that are in the freezer. Simply lift up on the right hand side, pull them away from the left hand side wall, we will also remove the lower bin and set that aside. Now, next we are going to remove six Phillips screws that secure that evaporator cover at the back. Now the next step to remove that evaporator cover we have reach under cardboard cover at the top and just gently pull that away. It fits into the website at the back there.

We don’t need to completely remove it, just pop it loose. We can now lift up on that evaporator cover and let it slide out of the opening. Lift up on it and you are just going to pick it a little bit sideways and pull it up past the shelf brackets and once we clear those two brackets for the lower bin you can twist it sideways and remove it completely from the freezer. Now that will give us access to the defrost thermostat and the wire harness connector.

So we are next going to disconnect the wire harness connector and the ground wire and unclip the thermostat from the tubing. You want to take care working in this area because the fins on that evaporator are very sharp.

free from the

So we will take a flat blade screwdriver, we are just going to go right in on the back right hand side, we will see where there is a green brown wire clipped to the back wall, just pop that up with our flat blade screwdriver, locate the thermostat, gently prod it to the clip on the back of it away from the tubing, and then we will note on the very back wall we have a wire harness connector. We will depress the locking tabs on that, pull that away, now we have the harness and the defrost thermostat where we can cut into that wiring and splice in a new one.

Now to replace the defrost thermostat with the new one, you will note that the new one does come with a length of wire leads on them, so we are going to cut the original ones just back from that 9-pin connector. So using a pair of cutters you will leave yourself an inch or two of wire, make sure we cut the right one, there is a pink one and a brown one and we will pull the old defrost thermostat out of that harness and discard it.

Next we are going to strip back the insulation on those wires and depending on the type of connector that you are going to use will dictate how much of the insulation you want to strip back. If you are using the butt type terminal, you want to cut back about 3/8th to 0.5 inch of the insulation. If you are using the inline type of splice typically about a 0.25 inch of insulation is always required.

We are going to use the inline types, I am just going to take our strippers and peel back about a quarter of an inch of that insulation, will twist that copper to make sure that it is tight. We will do the same thing on the brown wire. Then we are going to insert one of those splice connectors over the copper end of that wire, make sure that it is all the way inserted. Then we will take the clippers and squeeze it firmly. Just give a tug to make sure it is nice and tight.

We will do the same with the second wire. Next we will prepare the leads that are on the replacement thermostat, normally it will come with the insulation already cut and ready to peel off. We will just take the copper end and slide it into that connector, make sure it is fully inserted, again we will take our clippers, make sure it is bottomed in that connector and then crimp it tight. Do the same with the second one.

Because these are in a damp environment we suggest that you take a little bit of electrical tape and wrap those connections just to make sure we keep as much of the moisture away from those so that they don’t deteriorate. We will start taping that connection on the wire first, then wrap it up around the connectors. Then we will take a second piece and just tie all those wires together.

That will make a nice neat job when we are going to reinstall that harness in the refrigerator. Now, when reconnecting that harness assembly with the new defrost thermostat keep in mind the locking tab on that connector goes on the bottom, so we will start by inserting that into the receptacle at the back and push it in far enough so that you hear snap and lock into place. Just give it a sharp tug to make sure that it is connected properly.

Next, we are going to tuck that ground wire in behind and we will reconnect that to the back shield on that evaporator. We will use caution working near those evaporator fins as they are very sharp. Then we will use our flat blade screwdriver to push it on firmly. Next, we will reconnect the two single connectors to the defrost heater. Make sure the locking tab is engaged.

Then we will reconnect the wires to the evaporator fan motor. And again make sure that they are pushed on firmly. Now we will reattach the defrost thermostat to the tubing on the evaporator.

We are going to position it just back of this joint between the copper and the aluminum using the clips that is on the back of it. We will just spread that slightly. We are going to push that close to this adhesive.

Tuck that wire in behind, make sure it is free from the fan blades. Wrap that adhesive back against that defrost thermostat. Now we are ready to put the cover back on. So we are going to lift that up firm enough and between the shaft clips on the right, locate the arm and let it drop down.

There are two little tabs on the top of that evaporator fan motor bracket will fit into two slots on the cover, so make sure those are engaged. We will pull that down past where it needs to go. Just tilt it enough that you can lift that cardboard panel at the back up far enough over top of it. Then drop that cover down so that two little tabs on the evaporator fan motor bracket fit into the two slots then we can press that back cover back into position.

and then we will note

Now we can replace the six Phillips screws that hold up the cover in place. We won’t tighten them until we will have the screws all in position first, then we can tighten them all. Now we are ready to put the auger motor back in. Remember to pull the harness up over the top of that.

Just slide it in, hang it over the lower two mounting brackets, reconnect the harness, that locking tab goes on the bottom, make sure it snaps in place, we can lift the motor up into position and replace the 0.25 inch hex head screws and tug in all four screws securely. Next, we will replace the light bulb and the light bulb cover. There is a little tab in the front that we will locate first and then we will squeeze the sides in and clip in the two tabs on the side after.

Next we can put the lower bin and shelves in. Just put them into the left side first and then lower them down into the shelf bins on the right hand side. Next put the ice bin in, make sure it is back all the way and it is locked in position. We are now ready to reconnect the power and our repair is complete.

I told you it was an easy job, thanks for reading and good luck with your repair.
