What it is
The Potterton 840072 is a potentiometer wiring harness assembly for the Potterton Kingfisher MF range of gas boilers. It connects the potentiometer to the boiler's control circuit, carrying the signal used to set and regulate the appliance's operating temperature. The assembly is supplied as a complete loom for straightforward renewal where the existing wiring or connector has degraded.
Signs this part needs replacing
- Temperature control has no effect on boiler output or behaves erratically
- The boiler fails to respond when the potentiometer is adjusted
- Visible damage to the loom, such as cracked insulation, scorching or exposed conductors
- Loose, corroded or intermittent connections at the harness plugs
- Fault tracing points to a break in continuity through the potentiometer circuit
Before you order
- Confirm the appliance model against the fitment list above before ordering
- Check the existing harness and potentiometer for damage so the correct component is replaced
- Inspect the connector terminals for corrosion or heat damage that may also need attention
- Isolate the boiler electrically before carrying out any inspection or replacement work
