Relay Boards
The relay boards can be accessed by removing the
main rear access panel. The top relay board controls
the lower oven, and the bottom relay board controls
the top oven.
The lower oven relay board contains the power
supply module, which provides power to the rest of
the control system.
To remove the relay boards:
Remove the main rear access panel. (See 1. Rear
Access Panels.)
Mark and disconnect all connectors from the 2.
relay boards.
Remove the four 1/4-in. hex-head screws (2 on 3.
each side) that hold each relay board in place.

Lock Assembly
The motorized door lock assembly is located above
the oven and comes as a complete assembly.
Door Locking/Unlocking Strip Circuit
The cam on the motor performs two functions:
Positions the lock hook in the door to prevent 1.
opening during clean operation.
Operates the lock switches, which tell the 2.
control if the door is unlocked or locked and
ready for clean operation.
Note: When the door is either being locked or
unlocked, both the lock and unlock switches will
be in the open position. The upper oven latch is
controlled by the upper oven relay board. The lower
oven latch is controlled by the lower oven relay
board.
