PROBLEM POSSIBLE CAUSE(S) POSSIBLE ACTION(S)
Burner ignites, but will not stay
running and Burner shuts off on reset
within 15 seconds.
1. There is a fuel delivery problem.
2. The cad cell is dirty.
3. Cad cell wires are loose.
4. Cad cell / cad cell wires are
damaged.
5. The primary control is not
receiving the proper ohm signal
from the cad cell.
1. Follow the procedures listed in the
next problem.
2. Clean and check the condition of
the cad cell and cad cell wires.
3. Check that the yellow wires are
connected properly at the “F”
terminals on the oil primary
control.
4. Replace the cad cell and cad
cell wires. If the cad cell is heat
damaged: (a) Clean your furnace,
including the combustion
chamber, flues and stack. Refer
to instructions in Section 9. (b)
Check for backdraft caused by
exhaust fans in your building.
Follow instructions in Section 8.
5. Disconnect the yellow wires from
the “F” terminals. Start the burner
and check the ohm reading from
the cad cell. You have 10 seconds
to perform this test before the
burner shuts off on reset. Refer to
Section 7 to reset the oil primary
control. If the ohm reading is
above 500 ohms: (a) Check the
position of the cad cell; the cad
cell must “look” straight through
the central hole in the retention
head. (b) Check the position of
the retention head according to
Appendix A
Burner ignites and runs properly,
but the burner shuts off on reset
periodically (e.g. the burner goes off
on reset during the night and requires
resetting in the morning).
1. There is air in the suction oil line
due to leaks at the fittings.
2. There is air trapped in a high point
in the pressure oil line
1. Follow the procedures in Section 5
to vacuum test the pump. Reinstall
and properly seal the suction line
fittings to eliminate air leaks.
2. Bleed the air out of the pressure
oil line.
