Stirrer Blade
Distributes microwave energy throughout the cavity.
Blower/Fan Assembly
Circulates cooling air throughout the convection or
microwave oven compartment and cavity.
Stirrer Cover
Covers and protects the stirrer 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. It is actuated by door hook and guide
attached to the door.
Monitoring switch (contacts 7 and 8) is actuated by the
door guide.
The secondary interlock switch (contacts 2 and 3) and
primary interlock switch (contacts 4 and 5) are actuated
by the door hook.
The secondary interlock switch is in series with the
interlock monitoring switch in the monitor circuit.
If a malfunction occurs in the secondary 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 electomagnetic radio
frequency of 2450 MHz to heat the food load in the
oven.
Thermal Protectors
At a predetermined temperature the thermal cut-outs will
open or close. The oven will indicate an error code in the
display, initiate cooling fan operation, or prevent the
generation of microwave energy.
• Magnetron thermal cut-out is mounted directly on the
body of the magnetron
• Fan thermal cut-out is mounted directly on the
exhaust duct
• Control thermal cut-out is mounted directly on the
heater box
Touch Panels
Allows consumer operation and programming of oven.
Triacs
Triacs are controlled by high voltage circuit boards.
Triacs control one side of the power line going to the
high voltage power transformer and heating elements.
• Microwave triacs, heating elements A, and B triacs are
mounted inside oven chassis behind oven cavity front
bulkhead
RTD (Resistance Thermal Device)
Senses temperature inside oven cavity.
Heating Elements
Heating elements are used to produce convection heat.
