Application
This pressure switch is commonly used in Nordyne-branded furnaces and air handlers — including brands such as Gibson, Frigidaire, Tappan, Westinghouse, and others under the Nordyne umbrella — to verify that the inducer motor is creating adequate negative pressure before allowing the ignition sequence to proceed. Replacing a faulty pressure switch with the correct OEM part helps restore safe, efficient system operation.
