Vacuum Switch- Hudson River Saratoga Niagara V.2- replaces 720238- 720073
Vacuum switch for Hudson River Saratoga Niagara V.2. Part 720073 Replaces part 720238. The vacuum switch is a safety switch that shuts the pellet stove down if the combustion (Exhaust) blower fails. No longer comes with top part. 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.
