Common indicators include an unresponsive or malfunctioning digital display, inconsistent temperature or humidity levels, and error codes or warning lights appearing on the control panel. If the system does not respond to adjustments or you notice irregular performance, it may be time to replace the controller. Prompt replacement with a genuine Breezaire controller ensures your cooling unit continues to operate efficiently, protecting your wine collection from environmental fluctuations.
