Description
The Nordyne 632571R Pressure Switch is a safety control component used to monitor air or gas pressure levels. It responds to changes in pressure within the furnace or combustion air circuit and sends an electrical signal to allow or stop system operation based on set limits. Within HVAC systems, it is positioned in the control circuit to manage safe ignition and burner operation by detecting proper draft or airflow conditions. It is commonly used in residential heating equipment, ensuring correct pressure response during startup and operation cycles to support controlled system activity.
