Nordyne Pressure Switch 1010775R -0.20"PF

Nordyne / Miller / Intertherm 1010775R Draft Pressure Switch | OEM

The Nordyne 1010775R is a genuine factory-authorized draft pressure switch (also known as a combustion air or proving switch) designed for residential gas furnaces. As an Original Equipment Manufacturer (OEM) safety component, it is precisely calibrated to monitor the negative pressure created by the draft inducer motor.

This switch serves as a critical safety gate; it must close to prove that the inducer is moving enough air to safely exhaust combustion gases before the furnace is allowed to ignite.

Compatibility & Cross-Reference

The 1010775R is the manufacturer-designated successor for several legacy and obsolete part numbers:

  • Directly Replaces P/Ns: 632453R, 632453, 922486, 632332, 6323320, and 1014531R.
  • Equipment Fitment: Primarily used in Nordyne, Miller, and Intertherm M1 Series gas furnaces commonly found in manufactured housing.
  • Functional standard: This switch features two wiring terminals and two hose ports for a direct "plug-and-play" replacement.

Why Choose a Genuine Nordyne OEM Switch?

  • Fixed Calibration: This switch is factory-set at -0.20" WC (Water Column). Using a genuine part ensures the setpoint perfectly matches your heat exchanger's airflow requirements, preventing "nuisance trips" or unsafe operating conditions.
  • Combustion Safety: Engineered to automatically shut down the gas valve if it detects a blocked vent, failed inducer motor, or restricted heat exchanger.
  • Industrial Construction: Designed to withstand the heat and humidity fluctuations inside a furnace cabinet without the calibration drift often seen in universal aftermarket switches.
  • Direct Fitment: Includes the specific mounting bracket and port orientation required for a secure fit in the original furnace control area.
