Thetford Cooker Fan Thermal Cut-Out Sensor

This is a Thetford thermal cut-out switch fitted to the cooling fan assembly of SCK1500-series Thetford cookers, part of the K1500 range. It senses excess heat around the oven/grill area and cuts power to protect the appliance if temperatures run too high, and is a common replacement when a cooker's cooling fan fails to run or the oven cuts out unexpectedly during use. Thetford lists this sensor with tab-style spade connectors for a simple push-fit electrical connection.

• Brand: Thetford
• Manufacturer part number: SSPA0517
• Application: Thetford SCK1500 series (K1500/K1520/K1540) caravan cooker cooling fan circuit
• Connection: Spade tab terminals
• Function: Thermal cut-out / overheat protection sensor

• Q: What does this sensor actually do?
  A: It monitors temperature around the cooker's fan/cooling circuit and cuts power if things run too hot, protecting the oven and grill components from heat damage.
• Q: My cooling fan is not running, is this the cause?
  A: A failed thermal cut-out sensor is one possible cause of a non-running cooling fan; check the wiring and fan motor as well before replacing this part.
• Q: Does this fit my Thetford cooker?
  A: It is designed for the SCK1500/K1500 series of Thetford cookers. Check your cooker's model and data plate against Thetford's spare parts list to confirm fitment before ordering.
• Q: Is this a like-for-like replacement?
  A: Yes, it uses the same spade-tab electrical connection as the original Thetford-fitted sensor for a direct swap.
