Vacuum Switch- Ardisam Castle HPS09- Part 720109

Vacuum switch for Ardisam Castle HPS09 wood pellet stoves. Part # 720109. 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.
