Description
The Nordyne 1010775R is an OEM replacement SPST (Single-Pole, Single-Throw) pressure switch designed for use in Nordyne-family furnaces and air handlers. Set at a -0.20″ pressure factor (PF) trip point, this switch monitors negative pressure generated by the draft inducer blower to confirm proper venting before allowing the ignition sequence to proceed — a critical safety function in modern gas furnaces.
Key Features
- OEM Nordyne replacement pressure switch — ensures proper fit and function
- SPST (Single-Pole, Single-Throw) switching configuration
- -0.20″ PF (pressure factor) setpoint for precise draft proving
- Monitors inducer blower operation to confirm adequate venting
- Prevents ignition if proper negative pressure is not established — protecting against unsafe combustion conditions
- Direct replacement for compatible Nordyne, Gibson, Frigidaire, Westinghouse, and Tappan furnace models
Application
This pressure switch is a critical safety component in gas furnace systems. It senses the negative pressure (draft) created by the inducer motor and signals the control board that safe venting conditions exist before the burner is allowed to fire. A faulty or out-of-calibration pressure switch is a common cause of furnace lockout and no-heat calls.
Compatibility
- Designed for Nordyne-manufactured furnace brands including Nordyne, Gibson, Frigidaire, Westinghouse, and Tappan
- Always verify compatibility with the original equipment model number before installation
Why Choose an OEM Replacement?
Using a genuine Nordyne OEM pressure switch ensures the correct setpoint, connector configuration, and tubing port size — eliminating guesswork and reducing callbacks. Aftermarket substitutes may not match the precise trip pressure required by your specific furnace model.
