The same infrequency of starting would be the case if you had the
thermostat higher but it wasn't as cold out as it actually was.

That doesn't mean you're not right about it having trouble pumping the
oil.

the ignition gave up trying which shut down the pump, so I had to go
down and keep my finger on the little red button for a while, then it
was good for the rest of the cold snap.

A) Are we talking about a mechanical or electronic button/reset?

Probably electronic, although it was a slightly large button about the
size of the eraser on the end of a pencil which had a distinctly loose
and wiggly feel to it.

B) Isn't that symptom part of a different problem? I definitely
might be wrong about how it works, but I thought once you pushed the
reset button, the control energized the furnace for a certain time
period before it tripped again.

So doesn't that mean there is something wrong with the reset function
that you have to hold the button down longer than a second?

Maybe. IIRC, the first time I tried it, just pushing the button once
didn't make the furnace fire up, so my primitive half-frozen mind
determined to hold the damn button down until the furnace fired up or
blew up. Then I just stuck with what worked.

Well I don't at all know what the problem is, but I just wanted to
point these possibilities out.


Or are you saying you held the button down for that entire time period
so you were still holding it when it was ready for a second reset?

My oil furnace used to have trouble in the control box restarting.
Sometimes iirc I could feel the relay vibrating, and I looked into
replacing the relay, couldn't find a matching relay that would fit,
and eventually the thing settled down, and it's been fine for 5 years
or more now.
