Oil Burner won't start

Yesterday our oil burner inexplicably stopped working. I started by pressing the reset button, and nothing happened. I then checked the filters to see if they were clogged, but they were fine. The yearly tune up was done in march.

When I flip with emergency on/off switch absolutely nothing happens, there is no noise or any sort of smell.

Earlier today I used a current tester starting from the breaker box and worked my way through the assembly. It tested positive right up to the burner itself, the current just stops.

It is an older Utica boiler, the kind that have the reset button separate from the burner.

Out of curiosity I took an old extension cord and spliced it into the burner and then plugged into the wall, and it started up, so the current is being lost somewhere and I don't know where. The burner would work with the extension cord, but I really don't trust it, and it didn't turn off by itself after a few minutes like it usually does.

Any Ideas on what the problem could be?

Not sure what you mean by this. Is the reset button located on a stack control?

I meant that it's not attached to the burner. there's a cable that connects them, but they are not one piece

Did you click on the link in Rockledge's message?

We need to know if you are talking about a STACK CONTROL or not.

Is the box mounted on the FLUE PIPE?

Click this link ---> HowStuffWorks "How To Clean the Oil Furnace Stack Control"

Is this what you are talking about?

OK, good... in that case:

You can try the procedure for cleaning that control, but I sorta doubt you will have any joy with that. It's worth a [free] try...

If that doesn't work, you are looking at replacing the control.

By the way, it's a PRIMARY SAFETY DEVICE that senses if the burner is firing when it should be. Running the burner without this control as you have described is DANGEROUS! and other than for a short test such as you have done, it MUST NOT BE DONE! You are very smart to be 'uncomfortable' in doing so!
