What it is
The Viessmann 7822767 is a flue gas temperature sensor (thermistor) used on Viessmann gas boilers. It monitors the temperature of the flue gases leaving the appliance, allowing the control system to regulate combustion and shut the boiler down if flue temperatures rise outside normal limits. This sensor is listed for Vitodens WB1B and WB2B series appliances and Vitocrossal 300 Cu3A models.
Signs this part needs replacing
- The boiler locks out or shuts down repeatedly with a flue gas temperature related fault.
- Flue gas temperature readings are erratic, implausible or clearly out of range on the boiler display.
- The appliance cuts out shortly after ignition and will not run continuously.
- Resistance measured across the sensor does not track temperature as expected when tested.
- Intermittent faults that clear on reset but return once the boiler reaches operating temperature.
Before you order
- Confirm your appliance model and serial number against the fitment list above.
- Check the part number on the sensor being removed matches 7822767.
- Inspect the sensor connector and mounting arrangement against the item being replaced.
- Verify the fault lies with the sensor rather than the wiring or control board before ordering.
