I have a Ducane Heater that has a Honeywell automatic lighter on it and it simply won't light. I've had the igniter (spark plug type not glow) checked and it is fine. The green light flashes but it never lights. During the summer the condensation pump backed up and flooded the system. I see warnings on it about flooded systems. Do I need to replace the Honeywell or what? OUt of work and no money for service tech. Please help, family is cold.
