Help! Lennox mod G24M3/4-120A-4
Ser 6395M52686 12/95
LED shows lighting sequence normal (4 flashes I think) Gas valve opens, no spark (generator on board). During this time (approx 8 seconds) burner can be lit with lighter, runs about 8 minutes, then shuts off normally for about 4 minutes then attempts to relight but no spark. Tries 3 times, then locks out. Spark cable ok, Limit/ safety circuit closed- ok. Suspect board but owners can't afford- any other ideas?
Thanks
