Reznor Pressure Switch WC

The Reznor pressure switch (also called a draft pressure switch, air pressure switch or differential pressure switch) is a genuine OEM replacement part for Reznor gas-fired unit heaters and related commercial and industrial HVAC equipment. It monitors airflow and draft pressure in the combustion and venting system. It signals the control system when pressure reaches a preset water column (WC) setpoint.

Key Features:

• Safety control function: helps confirm proper venting and inducer or blower operation before ignition and during the heating cycle
• Calibrated WC setpoints: each switch in the line is built to a specific inches-of-water-column pressure rating, so it responds accurately to changes in airflow or draft
• OEM quality: made to Reznor's original equipment specifications for dependable fit and operation in compatible equipment
• Compact, durable construction: designed for demanding HVAC environments and simple installation and replacement

A failed or worn pressure switch can cause nuisance lockouts, burners that won't stay lit, or a heater that won't start. Replacing it with a Reznor switch helps restore safe, reliable operation. Choose the child item with the pressure setting and configuration that matches your original part.
