Common Questions

What does a 0.45" WC pressure switch do?
A 0.45-inch water column pressure switch monitors the negative air pressure created by the inducer motor. When the required pressure is reached, the switch closes to allow the ignition sequence to continue safely.

How do I know if the NS2-3126-00 is the correct replacement?
Verify the original part number, pressure setting (0.45" WC), electrical rating, hose connection, mounting style, and equipment model number before ordering. Using the correct pressure rating is essential for proper furnace operation.

Can this pressure switch be adjusted?
No. The NS2-3126-00 is factory calibrated and should be replaced with the same pressure rating specified by the equipment manufacturer.
