What it is

The Johnson & Starley ET001 is an electronics module (ET controls) supplied as a printed circuit board for the Hispec J25 appliance. It forms part of the boiler control electronics, handling the sequencing and monitoring functions of the unit. It is listed for the Johnson & Starley Hispec J25 warm air unit.

Signs this part needs replacing

  • The appliance fails to power up or run through its start sequence.
  • Heating or fan operation is intermittent, with the unit cutting out at random.
  • Fault or lockout indication appears and cannot be cleared by a reset.
  • Visible damage on the board, such as scorching, cracked tracks or swollen components.
  • Repeated blowing of the appliance fuse on power-up.

Before you order

  • Confirm the appliance model on the data plate matches the Hispec J25.
  • Check the existing board carries the ET001 part number before ordering.
  • Verify the fault lies with the module and not with the wiring, sensors or fan.
  • Isolate the electrical supply and follow the manufacturer's instructions when fitting.
