Winrich Negative Pressure Vacuum Switch
Genuine OEM replacement Winrich vacuum switch, part number MAR16. The replacement vacuum switch is used in all Winrich pellet stove models, including the Dynasty and Perfecta Freestanding and Insert models. Also referred to as the negative pressure switch or low draft switch, the vacuum switch senses air pressure in the firebox and exhaust flue vent pipe. The vacuum switch is in-line with the auger feed motor and will not allow the auger motor to run if it is tripped or faulty. Any air losses or air blockages can trip the vacuum switch. When experiencing issues with this safety switch, check the following: vacuum switch hose/tubing, firebox door and ash door gasket seals, ash accumulation in the stove or venting, air intake channel, combustion blower/exhaust fan functionality. Check out our video below to learn more about the pressure switch.
