What it is
The Worcester Bosch 87161208640 is a fan resistor harness — a wiring assembly with an integrated resistor that forms part of the fan circuit on Worcester 350 RSF appliances. It sits between the fan and the boiler control, carrying the supply to the fan motor and dropping the voltage across the resistor so the fan runs at the correct speed. It is a direct replacement for the harness originally fitted to these models.
Signs this part needs replacing
- The fan does not start when the boiler is called for heat, or starts only intermittently.
- The boiler locks out or shuts down shortly after ignition.
- Fan speed is erratic, or the fan runs at a fixed speed regardless of demand.
- A burning or hot electrical smell around the fan housing or control area.
- Visible scorching, discolouration or brittleness on the resistor or harness wiring.
Before you order
- Check the GC number and the appliance data badge to confirm the model before ordering.
- If you are working from older documentation, the previous number SPK0108 identifies the same harness.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
