What it is

The Glow-worm S1093800 is a sensor used on the Clearly Solar Thermal flat plate collector. It forms part of the appliance's temperature monitoring circuit, feeding readings back to the solar control so the system can regulate collector operation.

Signs this part needs replacing

  • Temperature readings from the collector are erratic, delayed or absent
  • The solar control shows a sensor fault or open/short circuit error
  • The pump does not run when the collector is clearly hot
  • Collector temperature displayed bears no relation to actual conditions
  • Intermittent readings that cause the system to cycle on and off

Before you order

  • Confirm the appliance model is the Clearly Solar Thermal flat plate collector
  • Check the existing sensor and its lead for damage, corrosion or a broken connection before condemning the part
  • Verify the fault is with the sensor rather than the wiring or control
  • Have the manufacturer part number S1093800 to hand when ordering
