What it is
The Baxi 7810675 is a limit thermostat used in Baxi Combi 2 appliances. It monitors temperature at its sensing point and interrupts the burner circuit when the set limit is exceeded, protecting the appliance from overheating. It is a safety-related control component within the boiler's temperature regulation circuit.
Signs this part needs replacing
- The appliance repeatedly locks out on an overheat condition and needs resetting.
- The boiler fires briefly then shuts down before reaching the expected flow temperature.
- Heating and hot water fail to run after a reset, with the overheat fault returning.
- The thermostat shows signs of heat damage, corrosion or a loose or broken connection.
- Continuity testing across the thermostat indicates it is not switching as expected.
Before you order
- Confirm the appliance model against the fit list above, including whether it is an LPG variant.
- Check the part number marked on the existing thermostat matches 7810675.
- Verify the fault is traced to the limit thermostat rather than a related temperature sensor, thermostat or PCB.
- Isolate the appliance and follow the manufacturer's instructions before removal and fitting.
