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.

Check the mounting of your old switch. This is direct fit for Pelpro and Breckwell pellet stoves. It will work on all other models with mounting adjustments.

Most newer stoves use the open terminal and common terminal for the electrical connectors and negative vacuum port. This means the exhaust fan is after the burn pot and connects to the venting and the switch is open until the negative pressure is applied.

Negative Pressure Hookup

Clip wires to farthest terminals from knob. Turn knob all the way to decrease. Connect hose to low port. Use this setting for the following pellet stoves.
