This Brivis over temperature switch (BS80009361) is a critical safety component for ducted gas heaters, designed to protect the unit from overheating by cutting power at 90°C. It's an essential spare for maintaining the safe operation of your Brivis system, especially for units manufactured after December 1998. You really don't want to skip checking these during a service; a failed overtemp switch means the heater runs until something else breaks, or worse, becomes a fire risk.

Tradie Pro Tip
When replacing any safety limit, always double-check the part number and the trip temperature. If the original switch faulted, it's worth investigating the root cause – sometimes it's a symptom of a larger airflow issue or dirty heat exchanger, not just a failed switch.
