What it is

The S00737 is a solenoid coil supplied by Johnson & Starley for use on its Eljan and Hijan appliance families. It forms the electrical coil element of the solenoid assembly, energising the valve it sits on to control gas flow. This listing is for the coil only, as used on Johnson/McLaren assemblies.

Signs this part needs replacing

  • The solenoid valve no longer opens or closes when the appliance is called to fire.
  • No gas is delivered to the burner despite the valve body being sound.
  • The coil shows signs of overheating, such as a swollen or discoloured body.
  • Intermittent firing or lockout traced to the coil circuit.
  • Continuity or resistance readings across the coil fall outside the expected range.

Before you order

  • Confirm the appliance model against the fit list above.
  • Check whether the coil or the complete solenoid assembly is required.
  • Verify the existing coil is a Johnson/McLaren type before ordering.
  • Have the appliance isolated and made safe before any work begins.
