What it is
This is a genuine Worcester Bosch air pressure switch, part number 8716117685, GC number 41-406-54 (also listed under GC numbers 41-406-60 and 47-406-73 for other appliance variants). It monitors the flue fan on the boiler and prevents the appliance from firing if the fan is not moving enough air, which stops harmful combustion gases building up without a safe means of dispersing them.
Signs this part needs replacing
- Boiler locks out on a fan or air pressure fault code
- Boiler fails to fire, or fires then cuts out shortly after
- Fan runs but the boiler still will not ignite
- Intermittent lockouts that clear on reset but recur
Before you order
- Check the part number and GC number printed on your existing switch against 8716117685 / 41-406-54
- Confirm your exact appliance model, as several GC number variants share this part number
- Isolate the boiler's electrical supply before removing any casing; have the switch fitted by a Gas Safe registered engineer
