Electronic Oven Control System
The Electronic Oven Control System consists of
the electronic control (ERC), key panel, oven
sensor, and door lock assembly.
Control Panel
There are 8 basic control panel assemblies. They
can be found listed by model number in the Con-
trol Panel Features section on pages 6 through 16.
Control Panel Access
1. Disconnect the power and open the oven door.
2. Remove 3 screws from across the bottom of
the control panel.
3. Push up on the control panel assembly to
release the top catches.
Note: See special instructions for Glass Touch
Models Only, page 25.
Electronic Range Control (ERC)
Caution: Components are electronically hot on
ERC 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 ERC to operate.
There are 7 basic ERC configurations (see illus-
trations). The ERC 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.
