What it is
The Worcester Bosch temperature limiter is an overheat cut-out device used across the Greenstar 4000 Combi and System Gr4700IW appliance families. It monitors boiler temperature and interrupts the burner circuit if the set limit is exceeded, protecting the heat exchanger and surrounding components from overheating. It is supplied under Worcester Bosch part number 8716121958.
Signs this part needs replacing
- Boiler locks out and requires a manual reset that will not clear
- Repeated overheat faults during normal operation
- Burner fails to fire even though there is a demand from the controls
- Fault code relating to an open or tripped limit stat circuit
- Intermittent shutdown once the appliance reaches operating temperature
Before you order
- Confirm the boiler model and GC number against the fit list above
- Check the existing limiter for a Worcester Bosch part number before ordering
- Verify whether the appliance uses a manual-reset or auto-reset limiter, as the two are not interchangeable
- Ensure gas supply is isolated and the appliance is electrically safe before any work
