DSI Monitoring System:
When power is applied to the range, a safety delay of 40 seconds takes place before the direct spark ignition control becomes operational. 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 either oven burner.
The self-test checks both solenoids on the gas distribution valve to verify that they are properly 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 appropriate 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.
Once the gas has ignited, the “flame safety circuit” will monitor the flame at the burner to make sure it is present. If a flame is not present at the burner:
a)The control will allow the ignitor to spark for 4 seconds.
b)A 40 second delay to dissipate any unused gas inside the oven will occur.
The ignition attempt will occur three times. If the burner does not ignite after the three attempts, the system will “lockout”
The control will perform an oven system lockout if:
a) Any of the self-test checks fail.
b) The oven fails to ignite after three ignition attempts.
c) A flame is present within the oven for more than 10 seconds after the gas valve is off.
d)The flame is unexpectedly lost for any reason after being established.
If this occurs, a lockout condition will occur after 30 seconds with no attempt to reignite.
During the lockout, the gas distribution valve and ignition are turned off. All lockouts can be reset by pressing the OFF/Cancel keypad on the Electronic Oven Control.
NOTE: There will be no indication on the electronic oven control display showing a lockout condition.
