I have a utica boiler installed in 1996 running a beckett

Customer Question

I have a utica boiler installed in 1996 running a beckett afg burner with a tiger loop system. The intermittent ignition relay keeps tripping. Honeywell R4184D1027. One service company said I have a vacuum leak yet the tiger loop has no bubbles and another company said I need a new fuel pump and wanted $450 to change a $65 pump. Any ideas why it's tripping? Combustion sounds good and fuel system is clean. The motor and fan turn freely. It trips sometimes after days of running at start up the furance is already firing.

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

There are several other possible causes besides a fuel issue. They are: improperly gapped electrodes, a weak transformer, a dirty or faulty cad cell or cad cell socket, even a bad nozzle. I agree that a fuel pump is an unlikely culprit. If your oil line fittings are not all flared fittings then the "vacuum leak" is a possibility. When this boiler was installed some of us were still using compression fittings which can develop a suction leak (not likely but possible).
