What it is

The Baxi 5114747 is an NTC sensor supplied by Baxi for use in its heating appliances. It is a thermistor-type component whose resistance changes with temperature, giving the appliance control board a continuous temperature signal to work from. Within the Baxi spares range it sits in the Thermostats, Thermistors & Sensors group, and it supports reliable, consistent operation of the appliance it is fitted to.

Signs this part needs replacing

  • Temperature readings that drift, sit outside the expected range, or fail to respond as the appliance heats up
  • The appliance cycling on and off, or cutting out shortly after firing, with no obvious mechanical cause
  • Hot water or heating temperature that fluctuates noticeably between calls for heat
  • Fault codes or lockouts on the control board that point to a temperature sensing circuit
  • Intermittent operation that clears after the appliance is reset, then returns

Before you order

  • Confirm the part number 5114747 against the appliance data badge and any wiring or parts diagram for the model
  • Check the GC number and serial number on the appliance so the correct variant is identified
  • Isolate the appliance from the electrical supply before removing or fitting the sensor
  • Inspect the sensor lead, plug and any sealing washer or O-ring at the probe as part of the same job, and replace them if they are damaged
