Recognizing the signs of a failing Breezaire relay is essential to maintaining your wine cooling system's performance. Common indicators include your unit failing to start or shutting down unexpectedly, inconsistent temperature or humidity control, and unusual clicking or buzzing noises coming from the relay. Visible damage, such as burn marks or corrosion on the relay board, is another clear sign that a replacement is needed. Addressing these issues promptly with a genuine Breezaire relay ensures your cooling system continues to operate reliably, protecting your wine collection from potential damage caused by temperature fluctuations.
