What Does This Part Do?
The vacuum switch is the stoves way of knowing it has an airflow through the venting in the proper direction. The vacuum switch is the stoves way of knowing it has an airflow through the venting in the proper direction. If the vacuum switch doesn’t see a pressure difference, it will will remain closed (closed circuit, electricity allowed to flow). When it opens (open circuit, electricity not flowing), the auger is stopped by depriving the stove of fuel and leading to shut down.
How Do I Know If My Switch Is Bad?
If an operational error occurs in the unit, a switch will either stop the top (feed) auger or shut the unit off; if the unit turns off an E-1 Code (error code) will appear in the Heat Range and Blower Speed windows of the Control Board. Situations which could cause this include power failure, Combustion Blower failure, improper flue installation, a blocked flue (from rodents, nests, etc.), or “dirty burning” from burning improper fuel.
