PROBLEM POSSIBLE CAUSE POSSIBLE ACTION(S)
Burner ignites and Burner shuts off on
reset sometime later during the day or
night.
1. There is air in the fuel supply.
2. The primary control is not
receiving the proper ohm signal
from the cad cell.
3. There is insufficient air pressure.
4. The heater block is cold.
5. The electrodes are fouled.
1. Prime the pump. If the pump will
not prime or there is air in the oil
stream from the pump bleeder,
follow the steps in the next
problem (“Pump will not prime.”)
2. Check for proper ohm signal.
Follow the procedures in the
previous problem (top, page 10-4)
3. Follow the instructions in Section
5 to adjust the air regulator for
proper air pressure. DO NOT turn
the air compressor off while the
furnace is operating. If you turn
the air compressor off at night,
turn the wall thermostat to OFF so
the burner will not run.
4. DO NOT shut off power to the
furnace overnight, or the heater
block will cool down, and the
burner will not re-start the next
morning. To turn the furnace “off”
overnight, turn the wall thermostat
to OFF. The heater block will stay
hot.
5. If oil residues have built up on the
electrodes and retention head,
follow the instructions in Section 8
to check for proper draft overfire.
Clean the electrodes and
retention head as shown in
Appendix A.
