I guess my question is, what keeps the oven safety valve open on a Whirlpool DSI (Direct Spark Ignition) system?
Answer Richard, The DSI spark module W10331686 has a "flame safety circuit" built into the board circuitry. " 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, The DSI will allow the igniter to spark for 4 to 5 seconds. After three attempts to ignite, the DSI will perform an oven system "lockout". You'll have to cancel the cycle and start all over again. The gas valve W10293048 solenoids have to "open" before the ignition spark occurs, of course it's somewhat instantaneous for the valve solenoid to open and the sparking to occur and ignite the gas, and flame is established.
Oven does not light. Replaced igniter and gas safety valve still does not light. What else could it be?
