WHat happens when you reset it? Does it start right up like normal? Does it smoke or rumble? Is it just one line feeding the burner?
I have a Carrier oil furnace with a Beckett burner model AFG. I have been having some difficulties with the reset button tripping.
I just recently transitioned from underground tank to above ground and also all new copper line filter etc. A week later I had to replace the transformer. This all happened about a month ago. I recently ran the new above ground tank empty for the first time. The service tech that installed the intake in the tank made sure to put the line a couple of inches off the bottom. I had fuel delivered today and every since the restart I have had to reset the button after each cycle. I have reset the furnace about five times and can't seem to understand any pattern why it is kicking back off. Sometimes the fan kicks on before it trips sometimes not.
I removed the fuel line and bled the lines. The nozzle was less than a month old with a new filter to boot.
Any suggestions as to what I might look for?

starts right up! I can look into the choke and see the flames coming up and hear the "rumble" of combustion. The last time I reset it, it tripped the reset and a few seconds later the fan kicked on and cycled.
could be cad cell, could be air, could be many things if you don't work on burners i'd call someone who does.
I just checked cad cell and it was free of debris or soot of any type (of course that says nothing of its functionality). I am not getting any smoke upon startup. Just good ol' fashioned combustion rumble for about 30sec to a minute followed by reset trip.
By the way, it has two lines feeding the pump.
Could be a burner motor starting to go bad, or a slipping coupling. Hard to tell without seeing it.
Best get your service tech back out there to look this over. A good burner tech will make sure that the settings and efficiency are right, also. A service call is well worth it.
could be a bad eye or control or just a to lean fire causing it to pull away from the head. You need a service tech
I think you mean it has one line feeding the pump and the other smaller diameter line on the pump feeds the nozzle. If so, your problem appears to be air in the suction line from running out of fuel.Originally posted by rustyblaster

Why the reason for drawing fuel from the top of the tank? Worst place. Now that the tank is inside, it should feed the burner from the bottom where the filter should be as well. Gravity feed is your friend, use it.
one line is the supply oil to the pump.the other is the return to the tank...did the pump get set up for a two pipe set up ? you may want to check to see if the by pass plug is in or out
A service tech determined it to be a nozzle problem. I guess a new nozzle can get plugged no matter how new it is? Thanks for the ideas though.
