What it is

The Firebird ACC000RTP is a red flow thermistor intended for the combi PCB on Firebird oil-fired boilers. It senses flow temperature and feeds that signal back to the control board so the boiler can regulate its operation. It is supplied as a single thermistor component for PCB-level fitment.

Signs this part needs replacing

  • Flow temperature readings that are erratic or clearly inaccurate
  • The boiler failing to fire or cutting out when a temperature demand is present
  • Hot water or heating temperature fluctuating beyond normal control
  • Fault codes or lockouts linked to flow temperature sensing
  • A visibly damaged, corroded or loose thermistor or lead

Before you order

  • Confirm your boiler model against the manufacturer's parts list
  • Check the existing thermistor colour and PCB connection point match this part
  • Verify the part number ACC000RTP against the component being replaced
  • If unsure of the fault, test the thermistor circuit before ordering
