A furnace pressure switch is another built-in safety mechanism we have in modern furnaces, it is designed to guard against dangerous gas leaks and prevent furnace cycling in the event of a mechanical failure. This improves the safety of your home and prevents further furnace damage.
Aside from its safety measures, this part also helps other parts of your furnace to work- it makes sure your inducer motor is producing the suction it needs, to remove the exhaust from your house. It also helps move heat throughout your home.
Pressure switches may vary according to the type of furnace you have in your home, if you are having any problems tracking down the perfect part you need for your unit, just contact us and we will be more than happy to assist you with your problem.
