How to Check for Bad Oil Burner Electrodes
- 1). Turn off the circuit breaker to the heating system.
- 2). Open the heater. Locate and open the black box where the electrodes are located. Look at the tips carefully; this is where the spark fires to ignite the oil. If the tips are corroded or covered with soot, clean them with alcohol and a soft cloth.
- 3). Examine the electrodes for cracks. If you find cracks, the electrodes must be replaced.
- 4). Check the connection between the electrodes and the oil burner. Any corrosion or loose connections must be addressed. Remove corrosion with alcohol or a solvent, and tighten the connections between the electrodes and the oil burner.
