POWER SWITCH, How To Replace:

MAKE SURE ALL POWER TO THE UNIT IS OFF. FAILURE TO DO SO MAY CAUSE
SEVERE EQUIPMENT DAMAGE OR PERSONAL INJURY!
A. Remove the Control Panel on the face of
the unit to expose the wiring connections
for the Oven or Proofer Power Switch [21
and 31].
B. Label and disconnect all wires to the
defective Switch.
C. Remove the Switch by depressing the
spring locking tabs on the top and bottom
of the Switch. The defective Switch
should now exit through the front of the
Control Panel.
D. Insert the replacement Switch from the
front of the Control Panel and press it into
place until the spring tabs are fully
engaged with the Control Panel.
NOTE: The replacement Power Switch must be installed so that the lighted segment on the front of
the toggle is at the top.
E. Reconnect the wires as tagged. The wire on the bottom Switch terminal should be the output to a
wiring junction connector. The wire on the center Switch terminal should come from the Power
Terminal Block [1]. The wire on the top Switch terminal should be a neutral (white) return line to
a wiring junction connector. Make sure all connections are clean and tight.
F. Replace the Control Panel on the face of the unit, being careful not to pull or pinch any wires
while replacing the panel.
G. Restore electrical power to the unit and test the Switch and its related controls for proper
operation.

DOOR MICRO SWITCH, How To Replace:

MAKE SURE ALL POWER TO THE UNIT IS OFF. FAILURE TO DO SO MAY CAUSE
SEVERE EQUIPMENT DAMAGE OR PERSONAL INJURY!
A. Remove the Micro Switch Cover Plate [73]
from the Hinge side of your unit. Carefully
peel back enough insulation from the side of
the Oven to expose the Micro Switch [15]
mounted just above the bottom Hinge in the
Oven door jamb.
B. Loosen and remove the nut securing the Micro
Switch in the door jamb, and remove the Micro
Switch with its wiring.
C. Disconnect the wires one at a time and install
them at the same locations on the new Micro
Switch. Make sure all connections are clean
and tight.
D. Turn one mounting nut onto the replacement
Micro Switch until it is approximately 2/3 of
the way down the threaded shaft.
