What it is
The Vaillant 090761 is a monitoring electrode used in Vaillant Mag CAR appliances. It sits in the combustion circuit and provides the flame monitoring signal that the control board uses to confirm the burner has lit and is burning correctly. If the signal is lost or unstable, the appliance will shut down and lock out as a safety measure.
Signs this part needs replacing
- Appliance lights, then locks out shortly after ignition
- Repeated lockouts with no obvious gas or ignition fault elsewhere
- Electrode tip shows heavy corrosion, pitting or carbon build-up
- Cracked or discoloured ceramic insulator on the electrode
- Unstable or intermittent flame signal during operation
Before you order
- Confirm the appliance model and variant against the fitment list above
- Check the existing electrode for damage, contamination or a poor lead connection before condemning it
- Verify the part number 090761 against the manufacturer's parts list for your appliance
- Inspect the electrode lead and its terminal, as a poor connection can mimic electrode failure
