Description
The Nordyne 632675 is an OEM replacement pressure switch engineered for precise draft pressure monitoring in Nordyne-brand furnaces and air handlers. Rated at 1.09″ water column (WC), this switch verifies that the inducer motor is generating adequate negative pressure before allowing the ignition sequence to proceed — a critical safety function that protects against incomplete combustion and flue-gas spillage.
Key Features
- OEM Nordyne replacement pressure switch for reliable, like-for-like performance
- Set point: 1.09″ water column (WC)
- Monitors inducer/draft blower operation to confirm proper venting before ignition
- Prevents furnace lockout caused by blocked flue, failed inducer, or restricted condensate drain
- Direct drop-in replacement — no modifications required for compatible Nordyne models
- Durable construction for long service life in demanding HVAC environments
Application
Designed as a direct OEM replacement for compatible Nordyne, Frigidaire, Gibson, Tappan, Westinghouse, and affiliated brand furnaces. Always verify compatibility with your unit’s model and serial number before installation.
Why Pressure Switches Matter
The pressure switch is a safety device that confirms the inducer blower is operating correctly and that the heat exchanger is not cracked or blocked. A faulty pressure switch can cause nuisance lockouts or, if bypassed, create dangerous operating conditions. Replacing a failed switch with the correct OEM part restores safe, reliable furnace operation.
