Quick check — and when it's not DIY
Start here — it costs nothing and rules out the easy cause: confirm the refrigerated display case has power and rule out anything obvious — a tripped breaker, an unlatched door, a blocked vent. If it's still acting up after that, if the basics check out, the fault is inside the control system or a sealed component, and diagnosing that safely takes a technician's tools and training.
