5-9-3 Bottom Thermal Cutout
THIS COMPONENT REQUIRE REMOVAL OF
MICROWAVE OVEN FROM INSTALLATION FOR
SERVICING.
During a fire on the stove the heat could be intense
enough to close the Hood Thermal Cutout and force
the fan to run. While at moderate high temperature we
do want it to run, however during a fire it is advantage-
ous to NOT have the vent fan running. So if a fire were
to start on the stove top the Bottom Thermal Cutout
would open at 212
O
F(100
O
C) and remove all power to
the microwave oven.
This cutout is designed to not be resetable.
To Remove Bottom Thermal Cutout :
1. Disconnect power and remove grille.
2. Remove control box assembly.
3. Remove two wire leads and unscrews one screw
capturing cutout on base plate.
5-9-4 Magnetron Thermal Cutout
The magnetron thermal cutout is located above the
leads to the magnetrons. It is designed to prevent
damage to the magnetron if an overheated condition
develops in the tube to cooling fan failure, obstructed
air ducts, dirty or blocked air intake.
Under normal operation, the magnetron thermal cutout
remains closed. However, when abnormally high
temperatures are reached within the magnetron, the
magnetron thermal cutout will open at 320
O
F(160
O
C)
causing the oven to shut down. After the temperature
drops to 140
O
F(60
O
C) it will reset and cooking will be
able to resume.
To Remove Magnetron Thermal Cutout :
