What it is
The Z474 is a gas valve control harness manufactured by Andrews for use in Andrews water heaters. It carries the electrical control signals between the appliance's control system and the gas valve, allowing the valve to open and close at the correct point in the firing sequence.
Signs this part needs replacing
- The appliance fails to fire or lights intermittently despite a call for heat
- The gas valve does not open when the control sequence reaches the ignition stage
- Fault codes or lockouts relating to the gas valve circuit appear on the controls
- Visible damage to the harness, such as frayed conductors, scorched insulation or loose crimped terminals
- Intermittent shutdowns that clear when the harness or its connectors are disturbed
Before you order
- Confirm the appliance model and that the existing harness matches the Z474 configuration
- Check the connector types and pin count at both ends of the existing harness against the part
- Inspect the gas valve and control board terminals for damage that may have caused the harness failure
- Isolate the electrical supply and gas supply before removing or fitting any component
