OVEN BURNER OPERATION
The spark ignition for the oven burners is
started at the Electronic Oven Control (ERC).
As the ERC is programmed for Bake or Broil,
the appropriate relay is closed on the ERC.
120 VAC is provided from L1, through the ERC
relay(s) to the direct spark ignition control at
input pin J1-6 (Bake), or J1-7 (Broil), to the
neutral side of the circuit, through output pin
J1-4.
This 120 VAC is used to generate two sparks-
per-second to both oven burners. The 120 volts
AC is also stepped-down to between 8 and 18
VDC through pins J1-1 and J1-2 (Bake), and
pins J1-3 and J1-2 (Broil). This DC voltage
opens the gas distribution valve, and provides
gas to the appropriate oven burner.
Monitoring System
When power is applied to the range, a safety
delay of 40 seconds takes place before the
direct spark ignition control becomes opera-
tional. The 40 second delay allows any unused
gas inside the oven cavity to dissipate before
a spark is activated. When the Bake or Broil
operation is activated, the direct spark ignition
control initiates an “internal self-test” and “flame
safety check.” The flame safety check takes
place anytime there is a flame present at ei-
ther oven burner.

IGNITION CONTROL
The self-test checks both solenoids on the gas
distribution valve to verify that they are prop-
erly connected. If they are not, the control will
turn the oven off, or lock it out. If the test is
successful, the control will then open the ap-
propriate valve, and initiate sparking at the
burner ignitor. Both the bake and broil ignitors
spark simultaneously. Sparking will not occur
until the gas distribution valve opens.
