Reznor rz018549 Venter Relay Fe Series

Product Description

The REZNOR rz018549 is a venter relay designed for use in FE Series heating equipment. A venter relay controls the operation of the venter motor, which draws combustion gases through the heat exchanger and out the flue. This component is a direct electrical control device that signals the venter to run during the heating cycle. Licensed HVAC technicians and commercial heating service professionals are the primary installers of this relay. It is a replacement part intended to restore proper venter motor sequencing when the original relay has failed or become unreliable.

This relay is specifically referenced for use in REZNOR FE Series unit heaters. FE Series equipment is commonly found in commercial and industrial applications such as warehouses, garages, and manufacturing facilities. When the venter relay fails, the venter motor may not start correctly, which can cause lockout conditions or prevent safe ignition. Replacing the relay restores normal heating cycle sequencing and proper combustion venting.

Key Features

• OEM-referenced replacement relay for REZNOR FE Series venter motor control
