What it is

The Morco FCB1080 is a thermistor used in Morco Products gas boiler appliances. It is a temperature-sensing component that allows the boiler's control system to monitor water or heat exchanger temperature and regulate operation accordingly. It is listed under Morco's gas boiler spares and carries the manufacturer reference N87G000M4.

Signs this part needs replacing

  • Boiler fails to fire or cuts out shortly after ignition
  • Domestic hot water temperature fluctuates or runs erratically
  • Lockout or fault codes relating to temperature sensing
  • Boiler short-cycles or modulates incorrectly
  • Resistance reading from the thermistor falls outside the expected range for the sensed temperature

Before you order

  • Confirm the appliance model against the fit list above
  • Check the existing thermistor's part number or manufacturer reference before removal
  • Inspect the wiring and connector for damage, corrosion or poor contact, as faults here can mimic a failed thermistor
  • Verify the fault with a resistance test at known temperatures rather than replacing on symptom alone
