Antenna Blades
Distribute microwave energy throughout the cavity.
Blower/Fan Assembly
Circulates cooling air throughout the microwave oven
compartment and cavity.
Grease Shield
Covers and protects the antenna blade assembly.
Door Interlock and Monitoring Switch
NOTE: When the line fuse is blown the Interlock Switch
Assembly must be replaced.
Interlock switch assembly mounts behind oven cavity
front bulkhead. Switches are actuated by the door
hooks.
Monitoring switch (contacts COM and NC) is actuated by
the top door hook.
The primary interlock switch (contacts COM and NO) is
actuated by the top door hook.
The logic switch (contacts COM and NO) is actuated by
the bottom door hook.
The secondary interlock switch (contacts COM and NO)
is actuated by the bottom door hook.
If a malfunction occurs in the primary interlock when door
opens, current will flow through the monitor switch
causing the oven fuse to open.
If a faulty door interlock switch has allowed current
through the monitor switch, the switch assembly must be
replaced (see interlock switch testing) before replacing
fuse.
DANGER
!
To avoid severe personal injury or death avoid
contacting any high voltage parts. The capacitors are
at high voltage (4000 volt) potential and it is extremely
important that they be grounded before handling.
Transformer High Voltage
High voltage transformer is used in this unit, which
supplies high voltage A.C. for operation of the magnetron
tube.
High Voltage Capacitor
Doubles the A.C. output voltage from the high voltage
transformer.
High Voltage Diode (Rectifier)
Is connected at the output side of the high voltage
capacitor. It changes voltage from A.C. to D.C. It passes
current in one direction and blocks it in the other. Also
called a rectifier.
Magnetron
With filament voltage and high D.C. voltage from the
output of the H.V. capacitor, diode junction, the
magnetron will put out an electromagnetic radio
frequency of 2450 MHz to heat the food load in the oven.
Thermal Cutout Protectors
At a predetermined temperature, the thermal cutout
protectors will open or close.
• Magnetron thermal cutouts are mounted directly on the
body of the magnetron
• Cavity thermal cutout is mounted directly on the left
side of cavity exterior.
Touch Panels
Allows consumer operation and programming of oven.
Triac
Triac is controlled by the electronic circuit board. Triac
controls one side of the power line going to the high
voltage power transformer.
• Triac is mounted inside oven chassis behind oven
cavity front bulkhead, towards rear of unit in front of
blower motor, underneath insulator.
Stirrer Motor
Stirrer motor rotates antenna assembly, located on top of
oven.
