What it is

The Worcester 8738213808 is an NTC temperature sensor from Worcester Bosch, supplied with a 500 mm lead and an R40 designation. It is a negative temperature coefficient thermistor, so its resistance falls as temperature rises, allowing the appliance control board to interpret the measured temperature. It is a service component for temperature sensing within Worcester Bosch heating and hot water equipment.

Before you order

  • Confirm the part number 8738213808 matches the number shown in the appliance documentation or on the existing sensor.
  • Check the lead length and connector arrangement at the intended sensing point.
  • Verify that an NTC sensor is the correct type for the circuit being serviced.
