What it is

The Andrews 7704040 is a wiring harness for the thermal switch on Andrews water heaters. It connects the thermal switch to the appliance control circuit so the switch can cut the appliance out when an overheat condition occurs. The harness is supplied for use with compatible Andrews models.

Signs this part needs replacing

  • The thermal switch does not operate and the appliance fails to fire or run.
  • Intermittent shutdowns or lockouts that point to a break in the harness wiring.
  • Visible damage to the harness, such as cracked insulation, exposed conductors or loose terminals.
  • Heat damage, scorching or discolouration at the harness connectors.
  • Fault codes or symptoms consistent with an overheat cut-out that will not reset.

Before you order

  • Confirm your appliance model against the fit list above.
  • Check the existing harness and connector arrangement matches the part.
  • Have the appliance model and serial number to hand when checking the manufacturer's parts list.
