Oven Burner Operation, Bake Operation

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 J1-1and J1-2(Bake), and pins J1-3and J1-2(Broil). This DC voltage opens the gas distribution valve, and provides gas to the appropriate oven burner.

Broil Operation

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.

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.
