How furnace pressure switch works

A furnace pressure switch is a safety device that ensures a furnace’s proper functioning. It works by monitoring the air pressure in the furnace and ensuring that it’s within the acceptable range. When the furnace is turned on, the pressure switch detects the pressure and sends a signal to the control board, allowing the furnace to continue operating.
 
If the pressure switch detects a pressure that’s too low or too high, it will shut off the furnace to prevent any damage or safety hazards. This can happen if there’s a blockage in the air intake or exhaust vent or a problem with the blower motor.
 
To ensure that your furnace pressure switch is working properly, it’s important to have it inspected and tested regularly by a licensed HVAC technician. They can identify potential issues and make necessary repairs or replacements to keep your furnace running safely and efficiently.
