    Why is oil not igniting in my Beckett Burner?

      If the Beckett Burner motor, drive coupling, and oil pump are operating, and oil is flowing to the nozzle through the solenoid valve, but the oil is not igniting, consider these possibilities: * Inspect the air shutter adjustment. If it's open too far, the airflow might prevent the arc from reaching the oil spray. Adjust the air shutter. * Check the battery and charging system to ensure a continuous supply of 11 to 16 volts DC (15 amps). * Check the electrodes for wear and damage, and make sure they are properly adjusted.

      If your Beckett Burner motor and igniter operate continuously but there is no flame and the oil solenoid valve is functional, you can check a few things: * Ensure that the oil nozzle isn't plugged. * If the coil on the solenoid valve is working, make sure the valve opens and closes correctly. * Verify sufficient fuel pressure. It should be 100 psig with the valve energized, unless specified otherwise. * Check the pump pressure and look for air in the fuel lines. * Inspect the burner for a broken motor coupling. If broken, check the pump rotation before replacing it. * Look for contaminated fuel and/or a partially plugged fuel filter.

      If the Beckett Burner blower motor is running and there's fuel in the tank, but no oil sprays from the nozzle, try these checks: * See if the coupling between the pump and motor is broken or stripped. * Check the pump output for oil. * Verify the oil valve operation. * Check for a plugged nozzle. * Check for air in the oil line. * Check for fuel contamination or a plugged filter.

      Stephanie MccallAug 21, 2025
      If the pump pressure on your Beckett Burner is erratic or nonexistent, check these potential causes: * Verify the motor's rotational speed. Low RPM can lead to unstable or absent pump pressure, so check motor rotational speed. * Inspect for a broken or worn motor coupling. * Ensure the pump turns freely. * Check for air leaks in the lines. * Look for oil froth at the bleed point. * Check the voltage at the motor. * Check for fuel contamination or a partially plugged filter.
