What it is

The Complete Electrical Panel (ET) is a Johnson & Starley control component, supplied under part number T193-0503000. It is the electrical panel assembly used on the Hispec J25 appliance, handling the unit's control and switching functions. It sits within the Controls category of Johnson & Starley boiler and warm air spares.

Signs this part needs replacing

  • The appliance fails to power up or respond when the panel is called for heat.
  • Repeated blowing of the panel fuse or tripping of the supply.
  • Burner or fan sequencing stops partway through the start cycle.
  • Visible heat damage, scorching or corrosion on the panel board or its terminals.
  • Intermittent faults that clear when the panel or its connectors are disturbed.

Before you order

  • Confirm the appliance model is a Johnson & Starley Hispec J25.
  • Check the existing panel's part number against T193-0503000 before removal.
  • Isolate the electrical supply and confirm the fault lies with the panel rather than external wiring, thermostat or sensor.
  • Note the connector layout and wiring order before disconnecting the old panel.
