What it is
The Worcester Bosch 87161566910 is a replacement photocell lead for the Satronic MZ770S burner control arrangement used on Worcester oil-fired boilers. The lead carries the flame signal from the photocell back to the burner control box, allowing the control to confirm that ignition has taken place and to hold the burner in its run state. It is supplied as the lead only and sits within the Cables, Leads & Wiring Harnesses spare part group.
Signs this part needs replacing
- The burner fires and then locks out shortly afterwards, with the lockout indication showing on the control box.
- Repeated lockouts on start-up that clear only after a manual reset.
- Intermittent flame detection, where the burner runs on some attempts and not on others.
- Brittle, chafed or heat-damaged insulation along the lead, or a loose connection at the photocell or control box end.
- No flame signal reaching the control box even though the photocell itself is clean and correctly seated.
Before you order
- Confirm the appliance model and serial number against the compatibility list before ordering.
- Inspect the existing lead and its terminations, as the part is supplied as the lead only.
- Any work inside an oil-fired appliance should be carried out by a competent engineer.
