My Harman XXV had a 17 year old vacuum switch that finally stuck closed. The auger and igniter would not work, as this switch prevents start up when it senses no negative vacuum. Perfect replacement and instantly got my pellet stove back on line.

This item replaced one from an older model. It was not exactly the same but, our friend who knows something about pellet stoves was able to make it work. It really made an improvement.
