Hi, it’s Steve from PartSelect. So you’re
thinking about replacing the heater and thermostat assembly on your refrigerator. It’s not
too bad of a job, the only tools required are a quarter inch nut driver and a pair of
needle nose pliers. The first step in the repair will be to remove
all of our shelving in the freezer unit to gain access to the defrost heater and thermostat.
There are also some screws that hold the evaporator cover in place, and the evaporator fan cover.
We will need to remove those to get god clear access to the defrost heater. Now that we’ve removed the screws from the
evaporator fan cover and the evaporator cover we tilt the evaporator fan cover forward to
get access to the evaporator cover, lift up on it, disengaging the tabs on the bottom,
turn it sideways and we can pull it out. Chances are your freezer is going to be covered in
ice. You’ll need to let that melt. Once it’s completely melted we can continue the
repair. Now that the ice and frost has melted off
of the evaporator we can see where our heater is located, across the bottom and up through
the side. There’s a clip that holds it in place here. We’ll need to remove that and
we’ll need to disconnect this harness. Now these edges are very sharp so take caution
when working near them. I suggest using needle nose pliers. Grip that clip and pull it forward
to release it. We’ll disconnect the harness. Press these two tabs and pull the harness
apart. In behind you will notice the defrost termination thermostat. Unclip that from the
tubing. Next we need to move this little foam padding
out of the way to get our harness through. We’re going to pull this little tube out
of here that’s holding the heater in place. Then we can remove the heater. To reinstall the heater keep the harness off
to the right here. Slide it up to the middle of the evaporator, roughly in place. Take
our piece of aluminum tubing, reinsert that. It will keep the heater from dropping out
of place until we install our clip. We’re going to engage the back side of that around
the back piece of tubing. Now you may be able to see this through from the front or you
may have to go by feel. Take our needle nose pliers, grip on the clip and that’s firmly
in place. Just check that and make sure it is locked in, the heater is centered. Pull
our wire harness up past the foam material. Be careful not to cut yourself. We’ll reinstall
the terminiation thermostat on the piece of copper tubing
and reconnect the harness. Tuck the harness
out of the way and we’re ready to put the evaporator cover on. Ok, we got our defrost heater and thermostat
assembly in place. Good luck with your repair.
