What should I do if 't3L' alarm appears on my IntelliCold® Pharmacy Refrigerator?
't3L' indicates that the low-limit detection probe detected a below-freezing temperature, which could harm stored products. The controller has temporarily stopped the compressor to allow recovery of temperatures; contact Labcold Service immediately for inspection or repair.
