Heating Help

burner keeps going out on safty evry 5to 6 hours

need help burner keeps going out on safety every 5 to 6 hours

does the

burner fire right up after you reset it? What oil burner do you have? (reillo, beckett ect) When was the unit serviced last?

It could be serveral things, i would start at the fuel tank , take a look at the oil filter, then check over the nozzle assembly, test the cad cell leads for resistance valves, .........

Keeps going out:

Slo is right.
Additionally, when the burner is getting ready to go out, goes it whine a lot? does it sound different after it is running for some time than after you reset it?
It needs service. You shouldn't be hitting the reset button. Call a service person. If it is a plugged filter, you are damageing the fuel pump.

still going out

its a beckette  i changed filter, screan ,new nosel cad cell and prim.control still is doing it but once a day to every 38 hours wound if its crap fuel

could be anything

from simple adjustments, to motor, control, puff switch if equipped, fan prover if power vented, pump and or coupling, transformer and or electrodes, resistor if older delayed oil valve, plugged/restricted oil supply-line, etc. Could be a lot of possibilities. Best to call a tech to check it out.
