Steve: Hi, it’s Steve from PartSelect. Today we are going to show you how to change the
defrost timer kit on your refrigerator. It’s a pretty easy job; all we are going to need
is a ¼ inch nut driver, a Philips screw driver and a putty knife. Let me show you how it’s
done. The very first step in this repair will be to disconnect the power supply from the
refrigerator. You can simply pull the cord from the receptacle, we can start our repair.
Now the defrost timer is located on the right hand side of this control housing, we need
to remove two quarter inch hex head screws that secure the housing to the ceiling of
the refrigerator. I am going to remove the two knobs in in the escutcheon and two remaining
quarter inch hex head screws behind. Two screws at the rear have a rather large flat washer
attached to them. So we can pop the two knobs off, now with the
putty knife just insert it in over the top edge and now gently pry that escutcheon forward.
There are some plastic tabs that hold that to the housing.
Do this as gently as possible so that you don’t break any of that tabs. You see the
series of tabs that fit into these slots along the front. Next we will remove these two ¼
inch hex head screws and have a slightly smaller washer on the head of those. As you remove
the last screw that support the housing capillary tube for the cold control that runs along this size. We don’t want
to pinch that, there is also linkage to the damper control as well. Frost timer is located
here and it’s held in place typically with two tilt screws, so you can remove those two
screws, we can reach in, locate your defrost timer, it should have a four pin plug on the
side of it. Disengage that plug; take note of the wire colors on that harness, because
at this point we will want to refer to the installation instructions that came with the
timer kit to maker sure that we connect it to the proper version of refrigerator that
you have.
Following those instructions we will locate the timer mode wire with the proper terminal
as per those instructions, simply force it down over this speed terminal. Locate our
wire harness, reconnect that, make sure it gets snugly, firmly in place. If you are existing
defrost timer utilize the two Philips screws, you will need to replace them with an inch
and a quarter long slot head screws. You may need to enlarge the holes a little bit just
with one instrument just open them up a little bit. Just make sure that the holes in the
control housing line up with the holes in the new defrost timer. The screw is fully
inserted with their hex nuts on. Then tighten the screws with the flat head screw driver.
You don’t need to use a socket on the notch, so typical just hold those you’re your fingers.
Now we will aligning the housing up to two holes in the front, reinstall quarter inch
hex head screws, next we will reinstall the two quarter inch hex head screws at the rear
of the housing, install the escutcheon on the front, tuck the bottom end first. Gently
press the tabs into place, fix the knobs, and our repair is complete. So now you know
how to change the defrost timer kit on your refrigerator. Thanks for watching and good
luck with your repair.
