Bard part number 3018-049 is an OEM electrical/control component used in Bard wall-mounted packaged HVAC equipment to help keep the unit operating as designed during normal call-for-cooling or heating sequences. If you are troubleshooting intermittent operation, a no-run condition, or control-circuit issues, replacing the correct factory-specified control part is often the safest way to restore reliable starts, proper staging, and stable system protection logic. Because the manufacturer-provided reference AE4-61-AK is not a complete functional description, confirm fit by matching the Bard part number 3018-049 to your unit model and serial tag or the unit’s official parts list before ordering to avoid mismatches in control voltage, terminal configuration, or revision level.
* Orders less than $50 may incure a minimum order fee.
