What it is

The Morco Products thermocouple locking nut (single) is the fixing that holds a thermocouple securely in its seating on compatible Morco appliances. It is supplied as a single nut under part number FW0566. Tightening it keeps the thermocouple probe in the correct position against the pilot or burner assembly so the flame-sensing circuit can work reliably.

Signs this part needs replacing

  • The nut will not tighten and spins or pulls loose on the thermocouple thread
  • Corrosion or mechanical damage prevents the nut from holding the thermocouple securely
  • The thermocouple works loose in service, causing the pilot or burner to drop out
  • The nut is seized or the threads are damaged, making removal at service difficult

Before you order

  • Confirm the appliance model matches one of the Morco appliances listed
  • Check whether a single nut or a multi-pack is needed for the job
  • Inspect the thermocouple thread and its seating for damage before refitting
