What it is

This is a Firebird capacitor rated at 5 µF, supplied as the CAPACITOR for Firebird oil-fired boilers. It provides the starting capacitance required by the burner motor circuit on the FB 4 R 35 LN Low NOx light oil burner. A failed capacitor typically leaves the burner motor unable to start reliably.

Signs this part needs replacing

  • Burner motor hums or buzzes without starting
  • Burner repeatedly trips to lockout on start-up
  • Motor starts inconsistently or only after several attempts
  • Burner fails to reach ignition despite a supply present

Before you order

  • Confirm the burner model is the Firebird FB 4 R 35 LN Low NOx light oil burner
  • Check the capacitance marking on the existing capacitor matches 5 µF
  • Isolate the appliance from the electrical supply before any inspection or replacement
  • Inspect the capacitor body and wiring terminals for swelling, leakage or heat damage
