Very likely air in the line. When you pour ten galons into a
275 gal tank, the liquid fuel covers the inlet tube by about
0.00001 inch. When the furnace pump comes on, it's really
easy to gulp some air. After you get your tank of heating
oil delivered, it should run better.

We have a brand new oil furnace and new tank. Our oil
delivery company
put a red flag on our old furnace and haven't delivered oil
for a
while. But the gauge on the new tank said we had 1/2 tank
left.

Thursday night we realized it was getting cold. To make a
long story
short, the furnace hadn't been on since noon that day. The
green light
on it was blinking. Resetting it didn't work. So we called
the guy who
installed it. Earlier that day we had a huge power surge,
lights
dimmed, tv went out, lasted 3 seconds. So I told that to the
repair
guy thinking that was the cause of the furnace no longer
working.

He ran a few tests, but no oil was coming through. This is
where my
terminology goes bad... he thought the pump wasn't working
because
the new magnetic switch on the pump it has may be fried. So
he put on
the old pump from our old furnace. Finally oil started
coming through,
spitting and sputtering. Then stopped after 10-15 seconds.

He went over to the tank, wiggled the gauge and it
immediately dropped
to empty. that brand new gauge had been stuck, it wasn't
half full, it
was empty....

So it was late, 10:30 pm, there wasn't much more he could do
for us.
So we called our oil delivery guys and they came out at
about midnight
and gave us 10 gallons of fuel. That guy got the furnace
started after
MANY attempts at priming it. But it started, heat was coming
out and
it worked so I went to bed.

Next morning it was very cold in our house. The green light
was going
off again. I really had no idea if we had gone through 10
gallons in a
six hour stretch.

So to my point....

I bought 15 gallons of fuel and put it on myself. As of
right now, I
can get the furnace started after many attempts of priming
it,
resetting it, etc, but once the house reaches the correct
temperature
and the furnace shuts off, it will not come back on by
itself. Green
light blinking.

Any thoughts? The guy that installed the furnace is coming
back but
I'm just wondering what the heck is going on? Sludge in the
line,
air??
