Englander Vacuum Shut-Down Switch Part CU-VS

Englander Vacuum Shut Down Switch, 0.05" WC. This is the "Door Ajar Switch." The vacuum hose from this switch connects directly to the firebox of the stove. This part is used in 2006 and later model pellet stoves.

2006 and later model pellet stoves use 1 ea CU-VS and 1 ea PU-VS. Pre 2006 models use 2 ea PU-VS.

The Vacuum Shut Down Switches (Part # PU-VS and CU-VS) help control various functions of the unit. 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.

NOTE: The "door ajar" vacuum switch port must be kept clean, or the top auger will cease to function. Locate the porthole to the right of the burn pot and, with the stove unplugged and cooled down, use a brush or pipe cleaner (not a vacuum) to keep this port clear of ash or other debris (see picture).
