Rheem Imperial Oil Furnance blowing cold air

I have a Rheem Imperial High Efficiency Oil Furnance ( ROBC-084QBEA ) with a Beckett RWB motor. The model # for the motor is AFG. I don't know anything about furnances and just noticed that its blowing out cold air, so I opened it up and the directions said to hit the red button which is located on top of the motor in a box. This worked a couple time but now just the fan is running. The oil tank is full and the filter is clean. Are their any simple steps to take..clean parts or check voltage.

Rheem uses a fan timer. When the thermostat calls for heat the fan comes on soon thereafter regardless if the burner fires or not.

Did you run out of fuel? If so, are there one or two copper lines from the tank to the burner?
