What it is

The MK11 high/low electrodes are a paired ignition component for Nuway oil burners, supplied under part number U90303A. They form the spark gap assembly used to ignite the oil and air mixture on high/low burner models. The electrodes are supplied as a matched pair.

Signs this part needs replacing

  • The burner fails to ignite, or ignition becomes intermittent
  • Visible erosion, pitting or cracking at the electrode tips
  • Sooting or carbon build-up bridging the electrode gap
  • Repeated lockouts at start-up despite a clean nozzle and oil supply
  • Spark tracking to earth rather than across the electrode gap

Before you order

  • Confirm the burner model and whether it is a high/low unit
  • Check the existing electrode type matches the MK11 high/low pattern
  • Verify that a pair is required, as this part is supplied as two electrodes
  • Have the burner make and model to hand when matching the part
