Service Diagnostics and Procedures
Broil Element
The unit uses a dual ribbon element to achieve the
broil function. The broil has four wires coming off
the rear and they connect to the control board.
To access the broil
element, remove
the door, remove
screws securing
the element, and
lower the element.
Verify resistance on
the inner and outer
broil element.
If no or infinite
resistance found
replace the broil
element. Verify
240VAC to the element. If no voltage is present,
verify the line break relay is closed, supply voltage
is available to the line break relay, and output from
the control board is supplied. If voltage is present
and the broil element does not energize, replace
the element.
Door Lock
The unit uses a door lock switch and door latch
switch to monitor if the door is open or closed and
locked or unlocked. In the unlock state the door
lock switch is closed and the door latch switch is
open. Once the end user initiates a clean cycle, the
door lock motor is energized. The motor rotates a
cam that changes the state of the door latch switch
from open to closed and the state of the door lock
switch from closed to open. Once the signal is
received that the door is closed and locked, the
bake and broil elements are energized at elevated
temperatures to clean food soils.
To access the door lock, remove the control panel
and the door lock is accessible. In the unlock state,
the door lock switch (green – blue) should be closed
and should open in the lock state. In the unlock
state, the door latch switch (green – orange) should
be open and should close in the lock state. Verify
resistance at the lock motor approximately 12.3
Ω.
Apply 120 VAC to the motor and it should start to
rotate.
