What it is
The complete electrical panel (ET) is a Johnson & Starley control assembly for the Hispec M31 warm air unit. It carries the appliance's electrical sequencing and switching functions, connecting the unit's components to the mains supply and control circuit. It is supplied as a complete panel assembly rather than as individual electrical components.
Signs this part needs replacing
- The warm air unit fails to power up or run through its start sequence
- The fan or burner cuts out intermittently with no obvious mechanical cause
- Visible scorching, arcing or heat damage around the panel, terminals or wiring connections
- Repeated tripping of the appliance's electrical protection
- Control functions behave erratically or stop responding altogether
Before you order
- Confirm the appliance is a Johnson & Starley Hispec M31 warm air unit
- Check the existing panel and its part number against the manufacturer's parts list before ordering
- Isolate the electrical supply to the appliance before any inspection or removal work
- Verify the fault lies with the panel itself rather than the wiring, thermostat or another control component
