This is how it is supposed to work

1. The inducer fan comes on
2. the igniter heats up
3. the gas valve opens
4. all the burners light
5. the flame sensor detects a flame
6. the plenum heats up
7. at a set temperature the fan comes on.

does #4 (AND #5) happen?

does the controll have a blink code self test?
