Worcester Bosch Burner Assembly Greenstar 87161163790

The Worcester Bosch 87161163790 is a burner assembly for Worcester Bosch gas boilers in the Greenstar range. It forms the combustion end of the appliance, delivering the gas/air mixture to the burner head and working with the burner controls to sustain a stable flame across the modulation range. The assembly is supplied as a complete burner unit, so it is the part to replace when the burner itself or its associated controls are at fault.

• The boiler locks out on ignition or fails to light consistently, with repeated reset attempts needed.
• The flame burns yellow or lazy rather than a steady blue, or lifts away from the burner head.
• Soot deposits or discolouration appear around the burner and heat exchanger.
• Combustion readings drift outside the expected range and cannot be corrected by servicing alone.
• Visible damage, corrosion or distortion to the burner head or its controls.

• Check the GC number and appliance serial plate against the compatibility list to confirm the correct burner for the model.
• Confirm whether the previous number 87181206160 or alternative number 1020153 is the number marked on the existing part.
• Check whether a gasket or seal kit is required for the burner joint on your appliance before refitting.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
