Lockout Valve - GE C2S985 Technical Service Manual

Lockout Valve

The range lockout feature (on some models), will
allow the user, thru the ERC control, to lock out the
surface burners, oven burners, and control panel, so
they cannot be activated. (See
purpose of the lockout valve is to shut off the gas
supply to the surface burners when this feature is
selected.
Note: The cooktop is locked out when the oven is in
self-clean mode. (See
Control Features
The lockout valve will not operate if a surface burner
is in the on position. The ERC AUX terminal sends
power across the surface burner switches, when
they are closed, to the motor lockout valve.
The gas lockout valve incorporates 2 switches to
allow the ERC to know the position of the lockout
valve. The yellow to orange wires close when
the valve is open, which allows gas to fl ow to the
cooktop. When the switch opens, the yellow to
silver wires close when the valve is closed. Loss of
the yellow to orange contact will cause the lockout
motor to run continuously, and LOC will fl ash in the
ERC display. Loss of the yellow to silver wires will
cause the lockout motor to run continuously when
LOCKOUT or SELF CLEAN is selected and LOC will
fl ash in the display. LOC will display steady when
the cooktop is locked out.
