5-9 THERMAL CUTOUT(TCO'S)
There are 4 different thermal cutouts in this unit with 4 different purposes. They are :
1. Oven thermal cutout (flame sensor), on cavity top.
2. Hood thermal cutout, on floor of control area.
3. Bottom thermal cutout, on floor of control area.
4. Magnetron thermal cutout, on magnetron.
5-9-1 Oven Thermal Cutout(Flame sensor)
The oven thermal cutout(Cavity TCO) is located
on the top side of the oven cavity beside exhaust
duct with a temperature rating of 212
O
F(100
O
C)
and is non-resetable.
The cutout is tightly held to the top of the oven
cavity by a spring clip.
NOTE
: If cutout cannot be removed from clip
oven will have to be removed from
installation and outer case removed.
5-9-2 Hood Thermal Cutout
This cutout will protect the touch control from
excessive heat by turning the vent fan on at low
speed. If the surface units of the range are used
for long periods of time heat will build up and
could damage the microwave control. In order
to prevent this a thermal cutout is installed on the
duct behind the control. This cutout will close
(158

(104

on temperatures it sense.
To Remove hood Thermal Cutout :
1. Disconnect power and remove grille.
2. Remove control box assembly.
3. Remove two wire leads and unscrew one
screw capturing cutout on base plate.
NOTE
: It this cutout were to open it would be
difficult to detect. The only time it functions
is during an overheat condition. It will be
normally open when checked with an ohmmeter.
