What it is

The Saunier Duval 0020127333 is a rectifier supplied as a service component for Saunier Duval appliances. A rectifier converts alternating current into direct current, so it sits in the low-voltage control supply side of the appliance rather than in the combustion or hydraulic circuit. It is listed by the manufacturer under part number 0020127333.

Before you order

  • Confirm the part number 0020127333 matches the number printed on the component or listed for your appliance model.
  • Check the fault diagnosis points to the rectifier before ordering, as low-voltage supply faults can originate elsewhere in the control circuit.
  • Isolate the appliance from the electrical supply and follow the manufacturer's wiring and safety instructions before fitting.
  • Verify any appliance-specific documentation for the correct rating and connector arrangement for your model.
