the igniter burns as soon as it runs. I replaced it twice, but the same problem occurs. What should I do?

Answer

If the igniter is getting constant power when there is a call for heat, and that's what's burning it up, then the circuit board is likely bad or the igniter is wired in wrong. But that is typically difficult to do.
