What it is
The Worcester Bosch 87186820100 is a control box assembly used on the Greenstar Ri ErP Compact range of regular (heat-only) gas boilers. It carries the boiler's control and connection points, linking internal wiring to the user controls and safety circuits so the appliance responds correctly to demand. It is supplied as a complete assembly, making it a direct replacement for a failed or damaged control box on the listed models.
Signs this part needs replacing
- The boiler does not respond to the programmer, room thermostat or front panel controls
- A blank or unlit display, or a panel that fails to power up
- Repeated lockouts or fault codes with no fault found elsewhere in the appliance
- Intermittent shutdowns or loss of power to the boiler
- Visible scorching, a burnt smell or heat damage around the control box
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the correct variant.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
- Confirm the assembly matches the control box removed from the boiler, as the Ri ErP Compact range uses more than one control configuration.
- Quote the alternative number 1031179 when cross-referencing with older documentation or other suppliers.
