Quick Answer
Fix a True commercial refrigerator that’s not cooling with step-by-step checks for airflow, gaskets, sensors, and components.
Common Fitment Questions
What should I verify before ordering a refrigeration replacement part?
Verify the model number, serial plate, old part number, dimensions, mounting style, voltage when applicable, and photos of the installed part before ordering.
Can appearance alone confirm compatibility?
No. Commercial refrigeration parts can look similar but differ by dimensions, voltage, connector, mounting pattern, handedness, profile, or equipment application.
What related parts should I inspect during repair?
Inspect nearby wear parts such as gaskets, hinges, latches, heaters, handles, fan blades, sensors, controls, wiring, and mounting hardware depending on the repair symptom.
True Refrigerator Not Cooling Properly? Causes & Fixes
If your True commercial refrigerator is not cooling properly, food safety and equipment performance are immediately at risk. This is one of the most common service issues across restaurants, convenience stores, and foodservice operations.
This guide explains the most common causes and step-by-step fixes technicians use to restore cooling.
Common Reasons True Refrigerators Lose Cooling
1. Dirty Condenser Coils
Dust and grease buildup prevent heat from dissipating.
2. Worn Door Gaskets
Air leaks force the unit to work harder.
3. Faulty Temperature Sensors
Incorrect readings cause improper cycling.
4. Blocked Airflow
Overloaded shelves restrict circulation.
5. Fan Motor Failure
Without airflow, cold air can’t distribute.
6. Refrigerant Issues
Low refrigerant reduces cooling capacity.
Step-by-Step Troubleshooting
Step 1: Check Condenser Coils
Clean coils with a brush or vacuum.
Step 2: Inspect Door Seals
Replace cracked or hardened gaskets.
Step 3: Verify Sensor Accuracy
Compare display readings with an external thermometer.
Step 4: Inspect Fans
Ensure evaporator and condenser fans are running.
Step 5: Reset the Unit
Power cycle to clear temporary faults.
When to Replace Parts
- Replace gaskets if seals fail
- Replace fans if airflow stops
- Replace sensors if readings are incorrect
- Replace controls if unit won’t cycle
