Reznor 203932 SPDT Pressure Switch 0.25 W.C.

The Reznor 203932 is a single-pole double-throw (SPDT) pressure switch designed for use in Reznor heating equipment. This precision switch operates at 0.25 inches water column (W.C.), providing reliable pressure sensing and control for proper unit operation.

Key Features:

• SPDT switching configuration for versatile control applications
• 0.25" W.C. pressure activation point for precise operation
• Factory specification part IS22025055F5192/B
• Designed specifically for Reznor heating systems
• Ensures proper venting and combustion air pressure monitoring

This pressure switch is a critical safety component that monitors air pressure differentials in the heating system. When proper pressure is established, the switch closes to allow the unit to operate. If adequate pressure is not present, the switch remains open, preventing unsafe operation. Genuine Reznor replacement parts ensure proper fit, function, and system reliability.
