Hi, the igniter stricking and going off is a function of the circuit board,,,,,,,,Now dont get nervous I see where you have replaced it.........From your question I see you have been all through this heater, And I'll help you figure out what is next
OK, I don't understand your response. I know the striker is controlled by the circuit board ( I have replaced it) and I expect the striker (ignitor) to go off . However, when the striker goes off the burner should remain on until the thermostat reaches set temp.
Where do I go from here?
Yes, I have a manual.
A couple of items that I don't understand. Looking at the wiring diagram in the manual I see 2 connections shown to the top of the circuit board, one is BLW and one is PWR. On my unit there are no such connections, just the plug which connects to ground, air and V1 plus the ignitor lead.
The other item is the ignitor has only two electrodes, one is grnd the other is HV (spark). How does the systmem sense the flame in order to keep the burner going once the ignition sequence is complete?
directly back through the ignition lead
As requested I have accepted your answer. How do we continue troubleshooting outside of the formal process?
