Bard 3003-004 - Alarm Wire Harness

The Bard 3003-004 Wire Harness - Alarm is an OEM electrical harness used to restore proper alarm circuit connections in Bard wall mounted HVAC equipment. When an alarm harness is damaged, corroded, or has loose terminals, alarm signals can become intermittent or fail to report correctly, which can lead to nuisance shutdowns or missed fault indications during service. This harness is built to Bard specifications for dependable connector fit and stable low voltage signal continuity, making it a solid choice when you need a direct replacement that matches the unit wiring layout and returns the alarm circuit to proper operation. Confirm compatibility by matching the part number to your unit model and wiring diagram before ordering.
