What it is
The Baxi 7662085 is a sensor supplied by Baxi for use in its 200 and 400 series combi boilers. It is classified as a thermistor, a temperature-sensing component used by the boiler's control system to monitor water temperature. The sensor feeds temperature data back to the PCB so the boiler can regulate firing and hot water delivery.
Signs this part needs replacing
- Boiler locks out or fails to fire, with a temperature-related fault code logged
- Hot water temperature fluctuates or runs hotter or cooler than the set point
- Heating circuit reaches temperature erratically or short-cycles
- Temperature readings on the display do not match the actual system temperature
- Intermittent faults that clear on reset and return once the boiler warms up
Before you order
- Confirm your appliance model against the fit list above, including whether it is the Combi 2, ErP or LPG variant
- Check the part number stamped or printed on the existing sensor matches 7662085
- Verify the fault code or symptom points to the temperature sensor rather than another component
- Have the boiler isolated and depressurised before removing the old sensor
