What it is
The Vaillant 0020192772 is a reset wiring harness used in Vaillant Arotherm air source heat pump installations. It forms the electrical link for the reset circuit, carrying the signal between the reset control and the appliance's control electronics. It is supplied as a single harness assembly for service replacement.
Signs this part needs replacing
- The reset function does not respond when operated
- Intermittent reset faults or repeated lockouts that clear only after the harness is disturbed
- Visible damage to the harness insulation, such as chafing, cracking or heat marking
- Corroded, loose or discoloured terminals at either end of the harness
- Continuity faults traced to the reset circuit during electrical testing
Before you order
- Confirm your appliance model matches one of the fitments listed above
- Check the existing harness for the part number marking before removal
- Inspect the mating connectors for corrosion or mechanical damage, as these may also need attention
- Verify the fault is in the harness rather than the reset switch or control board
