Common signs that a commercial refrigerator needs repair include: excessive condensation or frost buildup on the interior or exterior, long operating cycles that fail to maintain temperature, door seal or temperature control issues, unusual noises such as humming, rattling, or grinding (which may indicate motor or compressor problems), and inconsistent temperatures or a unit that frequently cycles on and off.
Any of these symptoms can lead to product loss if left unaddressed. Contact Polar Refrigeration at (877) 325-COLD for a diagnostic before the problem escalates.
