What it is
The Andrews G174 flow and return sensors are temperature sensing components used on Andrews water heaters. They monitor the flow and return water temperatures so the appliance control system can regulate heating and hot water delivery. The G174 covers the flow and return temperature sensing points on the appliance.
Signs this part needs replacing
- Hot water temperature fluctuating, or running hotter or colder than the set point
- Appliance locking out or failing to fire, with a temperature-related fault code
- Flow and return temperature readings that disagree with a known-good thermometer
- Sensor resistance outside the manufacturer's stated range when tested
- Intermittent faults that clear when the sensor wiring or connector is disturbed
Before you order
- Confirm your appliance model against the manufacturer's parts list
- Check how many sensors the appliance requires, as flow and return are separate sensing points
- Compare the connector type and sensor body against the part being removed
- Note any fault code displayed before ordering so the diagnosis can be confirmed
