What it is

The MHS Z856012420 is a temperature sensor supplied by MHS for use on gas boilers. It is a thermistor type sensor designed to be mounted on the side of the heat exchanger, where it monitors the temperature of the heat exchanger body and feeds that reading back to the boiler control. The part is listed under gas boiler spares in the thermistor category.

Before you order

  • Confirm the part number Z856012420 matches the sensor listed for the boiler being worked on.
  • Check the sensor is the heat exchanger side-mounted type, as the position of the sensor on the appliance determines whether this part is the correct one.
  • Inspect the sensor lead and connector on the existing part so the replacement wiring arrangement matches.
  • Have the boiler model and serial details to hand when cross-checking against the manufacturer's parts listing.
