I have an armstrong oil fired furnace with a canister type Garber filter. Everything has worked fine for the last 3 years, but now that I have changed the filter, I seem to keep getting air in my line and then the breaker trips.

The circuit trips about once a week, and has done it for 3/4 weeks in a row since changing the filter.

I primed the filter before i installed it, but if I didn't do that great of a job and there was still some air in it, would that explain whats going on?

I cant find any leaks anywhere

any help would be greatly appreciated

May have n air leak at the oil filters gasket. But that won't cause a breaker to trip.

"You seem to be getting air". How do you know that. Are you bleeding the sir at the oil burner pump? Get a catch can, a piece of 1/4" clear vinyl tubing and put it on the nipple on the oil pump. Open the nut behind it and purge the air. I'm with been there. An air leak will not trip a breaker. Do you mean the primary control is tripping on the cad cell do you? You don't have compression fittings on the oil line do you? Flare only on oil.
