This guide is for homeowners and heating engineers looking to maintain or replace a central heating sensor. The Worcester Bosch Central Heating Sensor (MPN: 87161423840) accurately monitors temperature to optimize your heating system's performance and efficiency, ensuring you only use the heat you need. A potential caveat is its specific compatibility with certain Worcester Bosch systems, requiring verification before purchase.

The sensor monitors the ambient room temperature and sends this information as an electrical resistance signal to the boiler's printed circuit board. This allows the heating system to adjust its output to maintain a set temperature efficiently.
Symptoms may include your heating system not reaching the desired temperature, running constantly, or cycling on and off too frequently. Inaccurate temperature readings displayed by your thermostat could also be a sign. It's best to have a heating engineer diagnose the issue.
No, installation should only be carried out by a qualified Gas Safe registered engineer. Incorrect installation can be dangerous and may lead to system malfunction or void warranties.
No, this specific sensor (MPN: 87161423840) is designed for certain Worcester Bosch models. Always check your boiler's manual or consult an engineer to confirm compatibility before purchasing.
The sensor's resistance increases as the temperature decreases (gets colder) and decreases as the temperature increases (gets warmer). This change in resistance is how the printed circuit board determines the current temperature.
Warranty information typically depends on the installer and the specific terms offered by Worcester Bosch or the retailer. Please refer to your purchase documentation or contact your installer for details.
Check if the sensor is correctly connected to the printed circuit board. Ensure there are no obstructions around the sensor and verify its compatibility with your boiler model. A faulty sensor may require replacement by a professional.
Verify the sensor is not located near a heat source (radiator, direct sunlight) or in a drafty area. Ensure the sensor's electrical connections are clean and secure. Professional diagnosis may be needed if the issue persists.
This could indicate a faulty sensor unable to provide correct feedback. Consult a heating engineer to test the sensor's resistance at different temperatures and confirm it is functioning within specifications.
Compatibility: This sensor is specifically designed for use with compatible Worcester Bosch central heating systems. Always verify the part number (87161423840) against your existing system's manual or consult a qualified heating engineer to ensure it is the correct replacement part for your specific boiler model.
Setup: Installation should be performed by a qualified Gas Safe registered engineer. The sensor is typically located in a position where it can accurately measure the ambient room temperature without being influenced by direct heat sources (like radiators or sunlight) or drafts. It connects to the boiler's printed circuit board via dedicated wiring.
Care: This is a low-maintenance component. The primary care involves ensuring it is not obstructed by debris and that its connections remain secure. Regular servicing of your central heating system by a qualified engineer is recommended to check the sensor's performance and the integrity of its connections.
