What it is

This part carries the manufacturer part number 05910500.
Signs this part needs replacing

- Appliance shuts down shortly after firing, once the heat exchanger warms up
- Repeated overheat trips with no obvious fault elsewhere in the heating circuit
- No heating or hot water because the safety circuit stays open
