What it is
The Worcester Bosch 87161076400 is a high limit thermostat used across the Greenstar Heatslave range. It monitors temperature inside the appliance and interrupts the burner when the set limit is exceeded, protecting the heat exchanger and surrounding components from overheating. It is supplied as a service spare for repair and maintenance work.
Signs this part needs replacing

- The overheat cut-out trips repeatedly and needs manual resetting
- Heating or hot water stops with no obvious fault elsewhere

- A fault code relating to overheat or the limit stat appears on the controls
Before you order
