How Long Should A Furnace Pressure Switch Last at Juanita Rose blog

How Long Should A Furnace Pressure Switch Last. Pressure switches also have a ‘tolerance’ rating of approximately 10%, so the 0.80” switch could open at 0.72” or 0.88” and be considered a correctly operating switch. They’re intended to last the life of the furnace, or 10 to 20 years. once closed, it will remain closed until pressure falls below 0.80”. This is known as hysteresis or differential. under normal conditions, the pressure switch activates and then allows your furnace to start safely. If those wires come loose or break altogether, then the pressure switch won’t. But there are always exceptions. how long do furnace pressure switches last? If there is an issue and the switch doesn’t. The furnace pressure switch acts as a safety device that monitors the air pressure within the furnace combustion chamber. Its primary function is to detect whether the combustion process is functioning correctly and whether there is sufficient airflow. the furnace pressure switch connects to a power source via wiring.
