What it is
The Broag UV Diode S39639 is a flame detection diode used in Broag commercial gas appliances. It monitors the ultraviolet light emitted by a burner flame and signals the control board that combustion has been established. The part is listed against the Broag commercial spare parts range and carries the reference P607.2 L&G.
Signs this part needs replacing
- The boiler locks out shortly after the burner lights, with no sustained flame signal.
- Repeated ignition attempts end in a flame failure fault.
- The burner runs for a short period then shuts down without an obvious gas or air fault.
- Flame detection faults appear intermittently, often worsening as the diode ages.
- The diode window is visibly sooted, clouded or damaged and cleaning does not restore a stable signal.
Before you order
- Confirm the appliance model against the manufacturer's parts list before ordering.
- Check the part number on the existing diode matches S39639.
- Inspect the diode window and its mounting for contamination or damage, as these can mimic a failed diode.
- Verify that the flame detection fault is not caused by ignition, gas supply or air settings before replacing the part.
