What it is

The Reznor ignition transformer (part 30-03-785) supplies the high-voltage spark for ignition in Reznor cabinet heaters fitted with Riello 40 burners. It sits within the burner ignition circuit, energising the electrodes to light the fuel-air mixture. This transformer is specific to the Reznor cabinet heater models listed below when a Riello 40 burner is installed.

Signs this part needs replacing

  • Burner fails to ignite and no spark is present at the electrodes
  • Repeated burner lockouts during start-up
  • Intermittent ignition or delayed light-up
  • Visible damage, swelling or burning on the transformer

Before you order

  • Confirm the appliance is a Reznor cabinet heater with a Riello 40 burner fitted
  • Match your heater model against the Fits list
  • Check the existing transformer part number and its terminal connections
  • Isolate the electrical supply before carrying out any work
