What it is
This is a Worcester Bosch temperature sensor, supplied under part number 87145000290. It is a direct-fit sensor used on the Worcester 24 SI II and 28 SI II RSF boiler range, along with the equivalent British Gas RD628 models. The sensor reports water temperature back to the boiler control, which uses that reading to regulate firing and maintain stable domestic hot water and heating output.
Signs this part needs replacing
- Boiler locks out or fails to fire despite a call for heat or hot water
- Domestic hot water temperature swings between hot and cold rather than holding steady
- Heating flow temperature reads incorrectly on the boiler display or controls
- Boiler short cycles, firing and stopping more often than normal
- Fault codes relating to temperature sensing appear on the appliance
Before you order
- Check the GC number on the appliance data badge against the compatibility list, as several SI II and RD628 variants use different sensor arrangements.
- Confirm the existing sensor carries part number 87145000290 or the alternative number 1013019 before ordering.
- Inspect the sensor pocket and any sealing washer on removal, as these are often disturbed when the old sensor is taken out.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
