What it is
The Potterton 5142134 is a screw-in temperature sensor for Potterton Commercial appliances. It is a boiler component that measures water temperature and feeds the reading back to the boiler control. It is listed for the Potterton Commercial Sirius FS range.
Signs this part needs replacing
- Boiler locks out or shuts down with a temperature-related fault code
- Unstable or erratic flow temperature readings on the boiler display or controls
- Domestic hot water or heating temperature runs hotter or cooler than the setpoint
- Sensor readings that do not change when the system is clearly heating up or cooling down
- Visible damage, corrosion or damp around the sensor body or its connection
Before you order
- Confirm the boiler model is a Potterton Commercial Sirius FS 400 or Sirius FS 525
- Check the existing sensor is the screw-in type and matches the part number 5142134
- Verify the fault has been traced to the sensor rather than the wiring or control board
- Isolate the appliance and depressurise as required before removal
