Nordyne 632656 Pressure Switch
When you're troubleshooting a furnace that won't ignite or is short-cycling, the Nordyne 632656 is a critical safety component to inspect. This Dual Pressure Switch .7/.2 WC is an authentic OEM furnace replacement part designed for many Nordyne-manufactured units, including those under Intertherm and Miller branding. As a veteran tech, you know that if the inducer motor is pulling but the control board is throwing an "open pressure switch" code, a ruptured diaphragm or a sticking internal switch is a likely culprit. This specific model features a dual-setpoint configuration with thresholds of 0.7" WC and 0.2" WC, ensuring the system accurately monitors both induction and flue pressure for safe combustion. Using a genuine Nordyne replacement pressure switch ensures the mounting bracket and vacuum ports align perfectly, preventing the nuisance trips often seen with generic universal kits.
Installation of the 632656 pressure switch is straightforward for any contractor familiar with the standard multi-terminal wiring of high-efficiency gas furnaces. By replacing a failing HVAC dual pressure switch with this factory-spec part, you restore the precise airflow proving required by the ignition sequence. This furnace pressure sensor is essential for preventing the accumulation of dangerous combustion gases, making it a non-negotiable fix for any residential or mobile home furnace repair. Don't waste time with off-brand alternatives that may not hold a consistent vacuum; stick with the factory pressure switch 632656 for a reliable, long-term solution.
Key Benefits:
- Exact OEM Specifications: Maintains 0.7" and 0.2" WC setpoints for precise air pressure monitoring.
- Enhanced Safety Compliance: Prevents the gas valve from opening if the exhaust venting or inducer motor fails.
- Broad Compatibility: Fits common Nordyne, Intertherm, Miller, and Tappan gas furnaces.
- Direct Replacement: Features standard terminals and port locations for rapid field installation.
Common Questions:
Why is my furnace blower running but I have no heat?
If the inducer starts but the igniter never glows, the Nordyne 632656 may be failing to "prove" the draft. This is a common safety lockout and typically requires testing the switch with a manometer and multimeter.
Can I use a single-stage switch instead of this dual-setpoint model?
No. This dual pressure switch is designed for systems that need to monitor two distinct pressure points. Using a single switch will result in error codes and system lockout.
What are the signs of a ruptured diaphragm in the 632656?
Technicians often report "fluttering" sounds from the switch or the furnace cycling off immediately after the inducer reaches full speed, indicating the internal diaphragm cannot maintain the required vacuum pressure.
