Refrigerator Not Cooling Even Though the Compressor Runs
In many True models, especially in commercial settings, this issue often stems from a dirty condenser coil or a blocked airflow path. True units use powerful fans and forced-air systems, and when airflow is restricted, the unit can't maintain proper temperature. Regular coil cleaning and checking fan operation are essential to restore performance.
Temperature Fluctuations During the Day
Unlike basic residential units, True refrigerators rely on highly responsive thermostats and digital controllers. If you notice the temperature swinging by several degrees, the issue could be a failing temperature probe or a malfunctioning electronic controller. Replacing the sensor or updating the firmware (for digital models) typically stabilizes the temperature.
Unit Keeps Running Without Cycling Off
If your True fridge runs continuously without shutting down, it may be due to improper door sealing or a defrost system failure. True doors are heavy and depend on precise gasket alignment. A broken door hinge, worn-out gasket, or failed defrost timer can cause the compressor to overwork, leading to increased energy use and premature wear.
Frost Buildup on Evaporator Coils
True refrigerators are designed to defrost automatically. However, if the defrost timer or heater malfunctions, thick frost can accumulate on the evaporator coils, blocking airflow and causing cooling issues. This is common in high-humidity environments like restaurant kitchens. Replacing the faulty defrost component and fully defrosting the unit are standard procedures.
Water Pooling Inside the Cabinet
Water leaking or pooling at the bottom of the cabinet typically indicates a clogged or frozen drain line. In True units, the defrost system routes water through a drain tube to an evaporation pan. If the tube is blocked, water backs up inside the fridge. Clearing the drain line and ensuring the unit is level usually solves the issue.
Interior Lights Not Working
If the interior LED lights flicker or don't turn on, the problem may lie in the door switch or the LED driver. Because many True models are used in commercial environments, constant door traffic can wear out the switch. Replacing the switch or driver board restores full lighting without affecting refrigeration performance.
While True refrigerators are known for their industrial-strength fans, excessive noise from the evaporator or condenser fan motor often signals bearing failure or ice interference. If the sound becomes irregular or high-pitched, inspecting and replacing the noisy fan motor is advised to avoid airflow disruption.
Digital Display Errors or Malfunctions
Some newer True models feature digital temperature readouts and control interfaces. If the display shows an error code, goes blank, or becomes unresponsive, it may indicate a faulty control board, power supply issue, or sensor failure. A technician can access the diagnostics mode to pinpoint the problem and reset or replace the board if needed.
