2. Remove 3 screws from across the bottom of
the control panel.

release the top catches.

Electronic Control (EC)

Caution: Components are electronically hot on
control when voltage is connected to range
Note: Temperature/Mode Selection is necessary
for operation of relay contacts.
Note: Voltage must be present across terminals
L1 to N for control to operate.
There are 5 basic EC configurations (see illustra-
tion). The control contains the bake and broil
relays, convection relay (some models), control
transformer, lock motor relay (some models),
sensor, and lock motor connector (some models),
along with a series of 1/4-in. terminals for connect-
ing power to the control and heating units.
