Nordyne 632656 Dual Pressure Switch .7/.2 WC

Description

The Nordyne 632656 is an OEM dual pressure switch engineered for precise draft and combustion air proving in Nordyne-brand furnaces and air handlers. By monitoring two distinct pressure thresholds — a make point of 0.7″ WC and a break point of 0.2″ WC — this switch confirms proper inducer operation before allowing ignition to proceed, protecting the heat exchanger and ensuring safe, efficient combustion.

Key Features

• Dual-function pressure switch monitors two pressure set points in a single component
• Make pressure: 0.7″ WC — confirms adequate draft inducer airflow
• Break pressure: 0.2″ WC — provides low-pressure safety cutoff
• OEM Nordyne replacement part — designed for direct, drop-in compatibility
• Helps prevent unsafe furnace operation due to blocked flue, failed inducer, or restricted venting
• Compact, durable construction for long service life in demanding HVAC environments

Application

Designed as a direct OEM replacement for select Nordyne, Gibson, Frigidaire, Westinghouse, and affiliated brand furnaces that utilize a dual pressure switch configuration. Always verify compatibility with the original equipment model number before installation.

Why Replace Your Pressure Switch?

A faulty pressure switch is one of the most common causes of furnace no-heat calls. Symptoms include the inducer running but the furnace failing to ignite, repeated lockouts, or error codes indicating a pressure switch fault. Replacing with the genuine Nordyne 632656 restores proper safety sequencing and gets systems back online quickly.
