    Hi Eff furnace continues to re-ignite
    The burner of our Luxaire Deluxe High Efficiencey PBNU-LD12N080D relights several times during same continuous purge blower operation. Sequence is as follows: 1. Purge cycle. 2. Igniter burns. 3. Burner flame ignites. 4. Igniter goes out. 5. 10-15 seconds later flame goes out. 6. Igniter re-energizes. 7. Flame comes on. 8. Igniter goes out. 9. 10-15 seconds later flame goes out again. 10. Igniter burns. 11. Burner flame ignites. 12. Igniter goes out. 13. Flame generally stays on until t'stat is satisfied, 13. Purge cuts out. 14. Fan blower cuts out when HX cools down. 15. Flame and purge blower stay off until next call for heat... (please note drains between pressure switches to condensate pump appears to be clear of condensate. I have found that if the condensate lines do not drain the purge blower will operate, but the burner firing will not take place... )

    Your suggestions are appreciated... Thanks, Vern
