What it is
The Satronic MZ770S 50003 is a photocell (light-sensitive flame detector) manufactured by Honeywell Satronic. It is fitted to oil-fired burner and boiler assemblies, where it monitors the flame and signals the burner control box to prove combustion. If the photocell does not register a flame, the control box will lock out the burner.
Signs this part needs replacing
- Burner fires then locks out after the safety time, with no flame signal registered
- Repeated or intermittent lockouts despite a visible, stable flame
- Burner runs but the control box does not hold the flame-proving sequence
- Photocell window is sooted, clouded or discoloured and cleaning does not restore reliable operation
- Erratic flame signal causing nuisance shutdowns during normal running
Before you order
- Confirm the existing photocell part number matches MZ770S 50003
- Check the burner or appliance model against the manufacturer's parts list
- Inspect the photocell holder and lead for damage before fitting a replacement
- Check the control box is compatible with the photocell type fitted
