• DEFROST RELAY

The Bard 8201-018 defrost relay is an OEM electrical control component used in Bard equipment to switch defrost-related circuits during heating operation so the unit can transition in and out of defrost at the right time. Using the correct relay helps prevent nuisance lockouts, protects the compressor and outdoor fan sequence, and keeps defrost operation consistent with factory wiring. Because relay styles and coil voltages can vary by model and vintage, confirm 8201-018 against your Bard unit model and serial number or the unit wiring diagram before ordering to ensure proper fit and function.
