Thetford Spinflo Thermocouple - 450mm

A thermocouple senses heat from the burner flame and holds the gas safety valve open for as long as that flame stays lit; if the flame goes out, it cuts the gas supply within seconds. This 450mm thermocouple with spade/Faston connector is the replacement for a range of Thetford Spinflo cooking appliances, including the Caprice MK3 and Triplex MK3 hobs and the Topline 3-burner hob. The usual symptom of a failing thermocouple is a burner that lights but goes out as soon as the control knob is released, or a burner that won't stay alight even after holding the knob in for the recommended time.

• Q: My burner lights but goes out when I let go of the knob, is this the part I need?
  A: Yes, that's the classic symptom of a worn thermocouple losing its ability to hold the gas valve open, and replacing it usually fixes it.
• Q: How do I know if I need the 450mm or a shorter thermocouple?
  A: It depends on which burner position it serves and the model of hob/grill, measure the length of the existing thermocouple from tip to the nut, or check your appliance's spare parts diagram, before ordering.
• Q: Can I fit this myself?
  A: It's a relatively simple swap for someone comfortable with basic gas appliance servicing, but if you're unsure, have a qualified gas fitter check the burner afterward for a correct flame and seal.
• Q: Does SSPA0676 and SPCC1132 mean there are two different parts?
  A: No, they're the same thermocouple listed under two part-number references used interchangeably by Thetford and its distributors.
