What it is
The Andrews 7702402 is a gasket for the exhaust thermistor fitted to Andrews Fastflo water heaters. It seals the thermistor mounting point on the flue, preventing flue gases from escaping and keeping the sensing point clean. This is a small but critical sealing component for safe and accurate flue temperature sensing.
Signs this part needs replacing
- Visible cracks, hardening or crumbling of the gasket material
- Flattened or deformed gasket that no longer seals against the mounting face
- Soot staining or signs of flue gas leakage around the thermistor
- Erratic thermistor readings or repeated appliance lockouts
Before you order
