Dryer Repair- Replacing the Thermal Cut-Off Kit (Whirlpool Part #279816)

Uploaded by partselect on 16.03.2011

Hi, it’s Steve from PartSelect. Today I’m going to show you how to change the thermal
cut-off kit on your dryer. It’s a pretty simple repair and you’ll need a few tools.
A quarter inch nut driver, perhaps a pair of needle nose pliers and a wire crimping
tool. Let me show you how it’s done.
The very first thing that we need to do is disconnect the power to the dryer. If it has
a plug merely remove that from the socket. If it’s a hard-wired dryer we need to find
the source and disconnect the power there. The second thing that we need to do is remove
the dryer vent. We need to pull the appliance out because all of this repair is going to
be done from the back.
Now we need to remove all of the screws holding the back panel on. On this model there are
nine quarter inch screws.
The location of the thermal cut-off kit’s two components located here and here. Ok,
the first thing we’ll do is change this top one. Remove the two wire terminals. Inspect
them to make sure they are good and clean. Remove this quarter inch screw. Lift the thermostat
out of the housing, note the little tab that holds it in place and replace it with the
new one.
Locate the tab in the hole and we’ll reinstall the screw. Replace the two wires, make sure
they are firmly seated on the connectors and we can move on to the second component.
To replace the lower thermostat we need to first remove the two wire terminals. Lift
the thermostat off of the terminal on the heater and pivot it out. If your thermostat
looks like this with an external wire attached we need to make some modifications for the
replacement part.
Our replacement thermostat looks like this. Now it will mount in place, there’s provision
for two screws. Install the large terminal wire to one end of the thermostat. The kit
comes with a jumper wire which has a large terminal on one end that will connect to the
element. On the other end it has a smaller quarter inch terminal. If your old thermostat
had this small wire on it we need to cut this off and crimp one this dual male-female terminal
in its place.
First we need to strip a little bit off the end of this wire, about a quarter of an inch.
Take our terminal, insert it fully inside and we’ll take our crimpers and firmly connect
the male-female connector to the end of the jumper wire.
Now we’ll take the small orange wire and we’re going to cut the end off of that and
install a quarter inch spade terminal on it. Again we’ll strip about a quarter of an
inch and we’ll crimp the terminal on. Make sure we have a firm crimp, nice and secure.
We’ll install the large end of the jumper wire on to the element terminal. Install the
new crimped end on to the thermostat and our third orange wire will go on to the male terminal
on that.
The last thing we need to do is put our back panel in place. And that’s just how easy
it was to change a thermal cut-off kit on your dryer. Thanks for watching and good luck
with your repair.
