What it is
The Worcester Bosch 87161164860 is an air and gas mixing chamber assembly. It sits within the combustion chamber of the appliance, where it helps combine air and gas for combustion. The combustion chamber itself is a sealed area that contains the burner and electrodes, capturing combusted gases so the fan can expel them through the flue.
Signs this part needs replacing
- Boiler fails to ignite or locks out repeatedly
- Soot deposits or discolouration around the combustion chamber
- Visible cracks, corrosion, or warping on the mixing chamber
- Fan runs continuously or error codes related to combustion
- Unstable flame or poor combustion readings
