Two different control boards, 120 volts on heater leads. Two different igniters, both check high 40s ohms, glow red when plugged into outlet. Stove runs great when lighting in the manual mode, runs great in auto mode when lite manually. Burn pot is clean, all holes are clean, stove is pulled and cleaned every ton. About half a ton run since last major cleaning. Started igniting slower and slower now not at all. At wits end.
