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
