Common Questions:

What causes a Bradford White limit switch to trip?
Tripping is typically caused by excessive water temperature, poor venting airflow, or scale buildup on the heating elements. If the switch trips frequently, professionals should inspect the blower assembly and thermostat settings.

Is the 233-41831-00 a manual or automatic reset switch?
This specific model is an auto limit switch, meaning it does not require a manual button press to restore the circuit once the unit cools down. If the system fails to restart, it may indicate a permanent switch failure or a persistent over-temperature condition.

Can I use this switch in non-'L' TTW models?
This part is specifically cataloged for the 'L' model dash series. Cross-referencing the serial number is recommended as Bradford White often uses specific thermal profiles for different BTU ratings and tank sizes.
