The burner is meant to run within the correct firing range. The burner requires the correct amount and type of oil, as well as the correct electrical supply. If the burner runs over capacity, it may refuse to fire, create soot or smoke heavily. Burners require very specific adjustments if broken. Failure to adjust properly can cause injury or death. Contact a certified professional to service the unit.
The burner is mounted inside the home in a well-ventilated area away from the oil tank. The wiring connections used by Beckett come from GeniSys. According to the Beckett owners manual, the GeniSys wiring colors may differ from the wiring colors used by Beckett. Fortunately, the wiring systems from GeniSys come with a manual or the wire connectors are labeled on the product. Make sure all wiring connections are intact to prevent misfiring of the oil pump furnace.
The burner of the oil pump comes equipped with a small control panel that has a red reset button installed in it. Press the reset button once and wait 60 seconds before attempting further troubleshooting. If the pump does not turn on, pressing the button will only flood the pump and prevent firing.
Disconnect the oil supply line from your Beckett oil pump and allow the oil to drain a bit into a bucket. Inspect the oil for signs of water. If there are, there is a leak in the system. Call out a service professional to have the pump drained and inspected for cracks that may prevent the system from igniting.
