Worcester Bosch Gas Valve 87161056540

The Worcester Bosch 87161056540 is a gas valve assembly supplied for the 24i Junior RSF and 28i Junior RSF natural gas appliance range. It sits in the gas train and controls the flow of gas through to the burner, allowing the appliance to light reliably and hold a steady flame through its operating range. As a serviceable component it is replaced when gas regulation becomes erratic or the burner can no longer be controlled correctly.

• The burner fails to light, or lights and then drops out shortly afterwards
• Repeated lockouts on ignition that clear only temporarily
• The flame is unstable, weak or cannot be modulated as the appliance changes output
• Gas regulation becomes inconsistent, with the appliance cycling on and off unexpectedly
• A smell of gas around the appliance or at the gas train connections

• Check the GC number on the appliance data badge against the numbers listed above, as the 28i Junior RSF was produced in more than one build
• Confirm the part number on the existing valve matches 87161056540 before ordering
• Inspect the gas train seals and gaskets while the valve is removed and replace any that are compressed or perished
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
