Furnace Switch Parts for Safe and Reliable System Protection
If your furnace shuts off unexpectedly, struggles with airflow, or fails to maintain stable heating, a faulty furnace switch may be the source of the problem. Furnace switches - including sail switches and limit switches - play a critical role in monitoring temperature, airflow, and overall system safety. When these switches fail, the furnace will shut down to prevent overheating or unsafe operation.
A failing furnace switch often leads to symptoms such as:
- Furnace shuts off soon after starting
- Weak or restricted airflow during operation
- Burner fails to stay lit due to airflow detection issues
These issues indicate the switch is no longer accurately sensing airflow or temperature conditions. Replacing damaged or worn switches is one of the fastest ways to restore safe and stable furnace performance.
