Lennox 22J53 Relay 322838-752 provided the system pressures fallFor mid to lower sequence staging in electric furnaces and air handlers, the Lennox 22J53 Relay is the industry standard for managing high amperage heating elements and blower motor timing. This genuine OEM sequencer (lower seq) relay operates on a 24V control circuit, providing critical load management to prevent simultaneous activation of multiple heat strips. By utilizing precise time delayed switching, it staggers the electrical draw, effectively
