What it is
The Andrews spill switch wiring harness, part number 7703874, is a wiring assembly that provides the electrical connection between the spill switch and the appliance control circuit. It is used on Andrews water heaters, including the Classicflo range. The harness carries the spill switch signal so the appliance can respond correctly when flue products are detected spilling from the flue path.
Signs this part needs replacing
- Spill switch faults that continue after the switch itself has been tested
- Cracked, brittle or heat-damaged insulation along the harness
- Corroded, loose or discoloured terminals at either end
- Intermittent lockouts or shutdowns traced to the spill switch circuit
- Continuity that fails when the harness is flexed or moved
Before you order
- Confirm your appliance model against the fitment list above
- Check the part number against the manufacturer's parts list for your model
- Inspect the connector type and terminal arrangement on the existing harness
