Dealing With a Refrigerator That Doesn’t Cool Properly

Today we’ll work on a Frigidaire refrigerator repair, we are going to be replacing the actual cooler controller or thermostats, which is mounted right here in the front. The reason why are replacing it is because it is not cooling correctly. The coldest it would get to is about forty-two degrees. And there is a dead spot between the three and the six on the thermostat and that is why we are going to be replacing it.

The tools you’ll need to complete this repair are:

  • a quarter inch nut driver and
  • a pair of needle nose pliers.

To begin the repair, go ahead and shut off the power or unplug the power supply under the refrigerator. Once that is done, first step you want to do is, using the pliers, just pull straight off the thermostat knob. It pulls right off.

The next step is: there are four quarter inch screws mounting the actual control panel, two up front and two in the back. So we want to go ahead and remove the four quarter inch screws, using the nut driver, to get access to the cold control. At the last quarter inch screw in the back, you want to go ahead and use your other hand, your free hand, to hold the control assembly, or else it’s just going to fall. Once all four screws have been removed, you can go ahead and slide the control panel towards you.

There is a Molex connector right here, that’s where all the wires connect into the cavity of the actual refrigerator. There are two clips that you want to go ahead and depress, once they are depressed, you just pull this straight off. Once we have unmounted the control panel, we have all the components here on the floor where we can work on it easily. The first steps that we want to do are to remove the ground wire and then the two wires that feed power to the thermostat.

First, the ground wire, we just grab a pair of pliers and pull right off and then we can go on the other terminals here. Once the wires have been removed, you can see that the thermostat is held in place by a couple of clips. You just want to go ahead and bend the tabs over, lift up on the thermostat and it will pull right up. Now we want to go ahead and unmount the thermostat bulb here. It’s a long wire and at the end of the thermostat wire there is a thermostat bulb and that’s what actually gets the temperature of the refrigerator.

Once we get as much wire as can out, we want to go ahead and remove the styrofoam diffuser. Be careful because it can break, you just want to go ahead and carefully lift up and set the two styrofoam pieces aside. Once they are aside, we can go ahead and flip the control panel over and we are going to go ahead and start unmounting it here from the three little clips, the plastic clips and as we do so, we’re want to go ahead and on the right hand side, remove the thermostat and then feed it through the left side hole.

Now we can turn it back over. Once we flip it back over, we can go ahead and straighten the wire and start fishing through the rest of the actual wires here in the front that are next to the timer and the light switch. Once the old thermostat has been removed, we do actually leave this sleeve here, the clear sleeve that goes on to the thermostat bulb. To do so, straighten it all the way and then you can just pull straight off. This is the thermostat. As you can see it comes coiled up.

What we have to do is go ahead and straighten the actual thermostat wire out. To do so, you just start to unwind the coil. Do it carefully, you don’t want to bend the actual thermostat bulb to a ninety degree angle. Once you got it to right about here, that’s when you can just grab it and pull straight out. Try and get it as straight as possible, because when we put the thermostat sleeve on the bulb, if it’s not straight, it is a little difficult to put on. The next step is to start inserting the thermostat bulb into the sleeve.

Again, go slow or else you don’t want to accidentally bend the actual thermostat wire. So the straighter the wire is, the easier it goes into the sleeve. Just like that. Now we are going to start fishing the thermostat bulb wire into the housing. You are going to do the exact same way that you removed the old one. Again, be careful, you don’t want to bend the thermostat bulb or wire into a ninety degree angle. Once we get to the end here, that’s when we can go ahead and actually fish the thermostat bulb into the opening on the right hand side.

Flip it over. As you can see, the bulb came out of the sleeve a little bit, so we want to go ahead and make sure that the bulb is actually in the sleeve. Just like that. So, we can continue to push the wire through and then once we have enough, we can go and clip the thermostat wire on to the plastic clips. Before you do the second last one, you want to go ahead and fish the thermostat bulb into the opening that’s on the right hand corner, once you flip it over. Just like that.

After the thermostat bulb has been reinstalled, we want to go ahead and reinstall the styrofoam diffuser. The easiest way to do it, because it comes in two pieces, instead of trying to figure out the puzzle, just put it together, both pieces, before you slide it into this slot. Once the two pieces are together, you can go ahead and push right down, make sure it’s nice and snug and it’s as simple as that. Next step is to remount the actual thermostat control.

Again, you are just going to line it up to where it’s supposed to go, squeeze, hold the tab back, insert one side, it’s not going to insert fully until we get the other side inserted, so just squeeze the other side, push down, as you can see it snapped in place. Once one of them is snapped in place, we can go ahead and snap the other one in place, we can just push straight down, just like that. Once it’s in place, we can go ahead and reinsert the wire where they are supposed to go.

The ground wire is an eight of an inch terminal, so it’s the smaller one, it goes by itself. The actual power wires are a quarter inch, it doesn’t matter what order they go in, they’re just completing the circuit. And also they just push right on. This is the drain, it was at the very back of the fresh fruit section, there is the actual drain. This knob is going to insert right into the drain, so make sure it is inserted or else when it goes into defroze, all the water will trip down below the crispers.

Now we are going to go ahead and reinstall the control panel here. Remember to put the drain hole into the actual drain below the crispers. So once this is installed you can go ahead and rest the console here at the top shelf, you want to go ahead and reconnect the Molex connector. Now it’s keyed to go on only one way, so just line it up and just push straight on. Once it’s inserted correctly, you’ll hear it snap into place. Once that’s done, we can go ahead and remount the actual control panel.

To do so, we are going to be using the four quarter inch screws we removed earlier. So go ahead and line up the control panel. I always like to start at the front. That way it will free my hands up. Once the control panel is mounted with the four quarter inch screws, we can go ahead and reinsert the thermostat knob right on to the thermostat here. The knob is keyed to go on to the thermostat only one way, so the larger arm is going to go on the bottom here in the larger slot, smaller arm in the actual hole.

So line it up and you will just push straight on. Once the thermostat knob is on, we can go ahead and reconnect the power and make sure that the refrigerator is operating correctly. That will complete your repair.
