We have an old oil furnace at church. It randomly goes into safety mode. We push the button and furnace comes on and runs up to temp
just fine. May run fine for 3 hours or 3 days. But at some point within a week the safety light will come on. 3 different techs have looked at it.
2 of them are 60+ years old with 15-30 years experience with oil furnaces.
Today the oil "GURU" came by and said "I am stumped." It worked perfectly for him.
New air and oil filter, new electronic board, new nozzle, flu cleaned, fire box vacuumed out, perfect flame, limiter working fine, etc.
Any of you got any ideas? The only thing that hasn't been changed is the pump. Intermittent problems are the worst.
