What it is

The Ferroli 39830120 is a test point for the modulating coil fitted to a range of Ferroli gas boilers. It provides a service access point on the modulation circuit so the coil signal can be checked during commissioning, fault finding and routine maintenance. It supersedes the earlier code 811060.

Signs this part needs replacing

  • The boiler will not modulate and holds a fixed burner output
  • Erratic or unstable burner modulation during demand changes
  • Fault codes or lockouts relating to the modulation circuit or gas valve
  • No readable signal at the test point when checked with a meter
  • Physical damage, corrosion or a poor connection at the test point

Before you order

  • Confirm the boiler model and product code against the fitment list above
  • Check the existing component for the part number 39830120 or the replaced code 811060
  • Verify the appliance GC number where one is shown on the data badge
  • Check the condition of the wiring and connector before fitting
