Bard part 3014-146 (CA4-24-KQ) is an OEM control contactor used in Bard wall-mount and packaged HVAC equipment to switch higher-load circuits from a low-voltage control signal. When a contactor is weak or chattering, you can see intermittent cooling or heating operation, nuisance shutdowns, or failure to pull in under load, so replacing it with the correct Bard-specified contactor helps restore reliable call-for-cooling or call-for-heat operation and proper staging. Because contactor configurations can vary by pole count, coil voltage, and terminal layout, confirm the unit model and wiring match before ordering to ensure a direct fit and correct electrical performance.
* Orders less than $50 may incure a minimum order fee.
