Vacuum Switch- U.S. Stove Forester- replaces 80567/ 720238-720073 #ARD720073#

Vacuum switch for U.S. Stove Forester pellet stoves. Part 720073 replaces 720238. and part 80567. Non OEM, but will work like the original part.  The vacuum switch is a safety switch that shuts the pellet stove down if the combustion (Exhaust) blower fails. If your pellet stove starts up then stops feeding pellets after the start cycle is over, then the vacuum switch is bad or the vacuum line is clogged with ash.  Also, if the auger motor does not turn you may have a bad vacuum switch.
