High Voltage Transformer; Left And Right Door Switch Assemblies - GE JK3800DH1BB Technical Service Manual

High Voltage Transformer

WARNING: Always be certain the capacitor is
discharged before servicing. (See the Capacitor and
Diode section in this guide.) Mechanically discharge
by placing insulated pliers between the diode
connection of the capacitor and the oven chassis
ground.
NOTE: The capacitor has an internal discharge
resistor that automatically discharges the capacitor
when the oven turns OFF. Under normal operation,
the capacitor should fully discharge within 30
seconds.
The oven must be removed to access the high
voltage transformer. (See the Removing Upper
Oven section in this guide.) The high voltage
transformer is located behind the top access cover.
The top access cover is held in place by two Phillips
head screws.
The transformer is held in place with four Phillips-
head screws. Two of the screws are recessed from
the top of the outer cover. Access holes are provided.
A magnetic screwdriver is necessary to capture
these screws.
When disconnecting the primary and secondary
wire connections, note the wire locations. The wire
connectors use releasing locking tabs.
Check the high voltage transformer windings for
approximate resistance value between:
Red to white
Red/Black

Left and Right Door Switch Assemblies

The primary interlock, monitor interlock, and
door sensing (secondary interlock) switches are
mounted on plastic latch boards. The latch boards
are attached to the left and right side of the oven
cavity. The left side latch board contains the door
sensing (secondary interlock) switch. The right side
latch board contains the primary interlock and the
monitor interlock switches.
