Description
The Lennox 71G17 Blocked Vent Switch M/R is a safety device that fits in the HVAC systems to eliminate the dangers of having blocked vents. This switch works by detecting high temperatures, normally at 300°F, as a sign of a blockage in the vent system. It has a manual reset function which means that in case of any obstruction, it will be corrected immediately before continuing with the normal operations. The advantage of this component is its capacity to protect HVAC systems to operate optimally and safely and also to increase equipment longevity.
