The Worcester 87161066330 Air Pressure Switch is a genuine replacement safety device designed to monitor the air pressure within your boiler’s combustion and flue system. It ensures that the fan and flue are creating the correct airflow before allowing ignition to proceed, helping protect internal components and maintain safe operating conditions. If the detected air pressure falls outside the safe range, the switch triggers a lockout to prevent unsafe combustion, so fitting the correct pressure switch is essential for reliable, safe boiler performance.

This air pressure switch is compatible with specific Worcester and Worcester Bosch boilers that reference part number 87161066330 in their parts documentation. To ensure proper fitment and operation, always verify the part number on your existing switch or consult your boiler’s service information before installation, as air pressure switch specifications and settings vary between models and series.

Supplied ready for direct replacement, the 87161066330 Air Pressure Switch connects with the boiler’s existing tubing and electrical harness without modification when installed by a qualified engineer. Choosing this genuine Worcester Bosch component helps restore accurate airflow monitoring and dependable safety control in compatible boilers.
