What it is
The Johnson & Starley wiring harness (MAF) is an electrical loom used on the MAF variant of Johnson & Starley warm air units. It forms part of the appliance's electrical wiring and is listed across the J15-22, J15-22R, J25-32 and J25-32R families, including Mk2, Mk3 and MAF VI versions. The same harness is specified for units supplied with Janus, Eljan, Hijan and Superjan water heaters.
Signs this part needs replacing
- Cracked, brittle or heat-damaged insulation along the loom
- Chafed or exposed conductors
- Corroded, loose or discoloured connector terminals
- Intermittent electrical faults or the appliance failing to run
- A burning smell or visible scorching at a plug or connector
Before you order
- Confirm the model and GC number from the appliance data plate
- Check whether the unit is the MAF or MAF VI variant
- Compare the connector layout and plug types against the harness being removed
