Cleveland Controls NS2-1023-00 Pressure Switch
The Cleveland Controls NS2-1023-00 Pressure Switch is a high-precision airflow sensing solution designed for the rigorous demands of residential and light commercial HVACR systems. This air intake pressure switch utilizes a durable glass-filled polycarbonate housing and a high-grade silicone diaphragm to ensure stable, contaminant-free performance across a wide operating temperature range of -40°F to 190°F. As a veteran technician knows, the NS2 series is the industry standard for proving inducer motor draft and monitoring differential air pressure in gas-fired furnaces and industrial atmospheric systems.
Engineering-grade silver contacts and an integral snap-acting SPDT switch provide reliable electrical load handling up to 5 Amps. The NS2-1023-00 is factory-calibrated for precision but engineered to accommodate various mounting orientations, featuring color-coded ports (Black for Positive, Gray for Negative) for rapid identification during field installation. Its compact small footprint air switch design allows for seamless integration into tight cabinets, making it a versatile choice for contractors performing exact-match replacements or custom OEM applications.
Key Benefits for the Contractor- Reliable Proof of Flow: Ensures the combustion byproducts are properly vented before allowing ignition, preventing hazardous conditions.
- Broad Environmental Tolerance: The polycarbonate body and silicone components resist degradation in extreme attic or mechanical room temperatures.
- Universal Integration: Equipped with standard 1/4-inch 90-degree quick-connect terminals and 3/16-inch ID sample line connectors.
- High Cycle Life: Rated for a minimum of 100,000 cycles at maximum electrical load, reducing the frequency of nuisance call-backs.
- Precise Differential Sensing: Offers a narrow switching differential to maintain tight control over airflow system safety.
How do I identify a failed pressure switch?
If the inducer motor is running but the furnace fails to ignite, check for a pressure switch stuck open. Use a manometer to verify the draft pressure against the switch's set point. If the negative pressure meets the requirement but the contacts don't close, the internal sensing diaphragm or switch mechanism may have failed.
What causes a "Pressure Switch Stuck Closed" error?
This typically occurs when the furnace control board detects a "closed" signal before the inducer motor starts. This safety lockout is often caused by a shorted switch or moisture/debris preventing the diaphragm from returning to its neutral position.
Can I use this switch for positive or negative pressure?
Yes. The Cleveland Controls NS2-1023-00 is versatile. For positive pressure, connect to the black port; for negative pressure (vacuum), connect to the gray port. For differential pressure, utilize both ports to monitor the pressure drop across a component like a filter or coil.
