Traulsen Refrigerator Compressor Running Constantly: Here's How to Fix

A Traulsen refrigerator is built for heavy-duty commercial use, offering precision cooling and dependable performance in demanding kitchen environments. However, when the compressor runs constantly, it signals that something isn’t right. Continuous compressor operation can lead to higher energy bills, premature wear, and temperature inconsistencies that affect food safety. Understanding why your Traulsen refrigerator compressor is running non-stop is crucial for preventing costly breakdowns and maintaining peak efficiency. In this guide, we’ll explain how to identify the problem, explore common causes, and share effective solutions using genuine Traulsen replacement parts and Traulsen refrigerator parts to restore proper performance.

How to Tell If Your Compressor Is Running Too Often

Your Traulsen refrigerator’s compressor is designed to cycle on and off throughout the day to maintain consistent internal temperatures. However, when it runs too frequently or continuously, it’s usually a sign that the system is under strain. Detecting this early can help prevent energy waste and mechanical damage.

Here’s how to recognize if your compressor is running too often:

• Constant Humming or Vibrating Noise: A healthy compressor operates in cycles, typically running for a few minutes and then shutting off. If you hear a continuous humming or vibration that doesn’t stop for hours, it’s likely running non-stop.

• Higher Energy Bills: Continuous compressor operation demands more electricity. If your energy costs suddenly increase without a change in usage, the refrigerator may be overworking to maintain temperature.

• Warm Exterior Surfaces: When the compressor runs excessively, heat builds up around the rear or sides of the refrigerator. This is a clear sign of overuse or poor heat dissipation due to dirty coils or restricted airflow.

• Frost or Ice Accumulation Inside: Excessive frost on evaporator coils or the back wall indicates that the defrost system isn’t functioning properly. This causes the compressor to compensate by running longer cycles.

• Temperature Fluctuations in Storage Compartments: If the interior temperature doesn’t stay stable even with the compressor running, the problem may lie in the thermostat, sensor, or door seal.

If you notice one or more of these symptoms, it’s crucial to investigate further before the compressor suffers permanent damage. Using genuine Traulsen replacement parts or Traulsen refrigerator parts during repairs will ensure reliable performance and help restore your refrigerator’s normal operating cycle efficiently.

Common Reasons Why Your Traulsen Refrigerator Compressor Runs Continuously and Their Fixes

Several factors can lead to a continuously running compressor. Some are simple maintenance issues, while others may require Traulsen replacement parts or professional servicing. Let’s explore each in detail:

Incorrect Temperature Settings

If the refrigerator’s thermostat is set too low, the compressor must work longer to maintain excessively cold temperatures.

Fix:

• Verify the thermostat settings according to the manufacturer's recommended temperature range, usually between 36°F and 40°F (2°C to 4°C) for most Traulsen commercial refrigerator models.

• If the thermostat or control board is unresponsive, consider replacing it with an authentic Traulsen refrigerator part that matches your model.
  

Dirty Condenser Coils

Condenser coils dissipate heat from the refrigerant. When they’re covered in dust or grease—common in commercial kitchens—the system struggles to release heat, forcing the compressor to run longer.

Fix:

• Disconnect the power and clean the coils using a coil brush or vacuum.

• Perform this maintenance every 3–6 months to maintain energy efficiency.

• If the coils are corroded or damaged, replace them with Traulsen replacement parts for proper fit and performance.
  

Worn or Damaged Door Gaskets

A faulty door gasket allows warm air to enter the refrigerator, causing temperature fluctuations. The compressor then compensates by running continuously to maintain the set temperature.

Fix:

• Check the door gaskets for any cracks, tears, or looseness.

• Replace damaged gaskets immediately.

• Use authentic Traulsen spare parts for an airtight seal.

• Ensure consistent internal temperatures with proper gasket maintenance.
  

Blocked Air Vents or Poor Air Circulation

Blocked vents or improperly arranged items inside the refrigerator can obstruct airflow, making it difficult for the system to maintain uniform cooling.

Fix:

• Maintain adequate spacing between items for optimal air circulation.  

• Regularly clean the evaporator fan area to eliminate dust and debris.  

• If the fan motor is not functioning properly, consider replacing it with a compatible Traulsen commercial refrigerator part to restore effective cooling cycles.
  

Faulty Evaporator Fan Motor

The evaporator fan distributes cool air across the compartments. A malfunctioning fan can lead to uneven cooling and force the compressor to overwork to compensate.

Fix:

• Check if the fan is spinning freely and quietly.

• If the fan motors are noisy or stuck, replace them with compatible Traulsen replacement parts.

• Regular cleaning of the fan blades can prevent debris buildup and prolong lifespan.
  

Defrost System Malfunctions

If the defrost system fails, frost accumulates on the evaporator coils, restricting airflow. The compressor must then run longer to maintain temperature.

Fix:

• Use a multimeter to test the defrost timer, heater, and thermostat.

• Replace any faulty components with certified Traulsen refrigerator parts.

• Ensure the defrost system operates properly to restore normal compressor cycling.

• Prevent energy waste by maintaining an efficient defrost system.
  

Low Refrigerant Levels or Leak

A refrigerant leak reduces system pressure, making the compressor run constantly without achieving adequate cooling.

Fix:

• Refrigerant-related issues must be addressed by a certified technician.

• Identify and repair any leaks in the system.

• Refill the system with the correct refrigerant type as recommended by Traulsen replacement parts.

• Avoid using non-compatible refrigerants or parts to prevent compressor damage.
  

Faulty Temperature Control Board or Sensor

The electronic control board regulates compressor activity based on sensor readings. If the board or sensor malfunctions, it may send incorrect signals, causing the compressor to run continuously.

Fix:

• Check the control board for any signs of burnt marks or damaged wiring.  

• If necessary, replace them with authentic Traulsen parts.  

• This ensures precise temperature monitoring and effective system control.  
  

Excessive Door Opening in Commercial Settings

In busy kitchens, refrigerator doors often remain open longer than necessary. This allows warm air to enter, causing the compressor to work harder to maintain temperature balance.

Fix:

• Encourage staff to minimize door openings.

• Ensure doors are closed promptly.

• Consider installing self-closing hinges.

• Explore the use of door alarms.

• Utilize Traulsen commercial refrigerator parts for improved operational efficiency.
  

Aging or Overworked Compressor

Over time, compressors naturally wear out, especially in high-use commercial environments. An aging compressor may lose efficiency and require replacement.

Fix:

• Check if other components are working correctly.

• If the compressor runs excessively, consider replacement.

• Use original Traulsen replacement parts for best compatibility.

• Ensure consistent performance with the original part.

When your Traulsen refrigerator compressor runs constantly, it’s a clear indicator that the system is struggling to maintain proper cooling balance. Ignoring the issue can lead to unnecessary energy consumption and potential damage to key components. By identifying the root cause—whether it’s a faulty thermostat, dirty condenser coils, or worn gaskets—and replacing damaged parts with authentic Traulsen replacement parts or Traulsen refrigerator parts, you can restore efficiency and reliability. Consistent maintenance, periodic inspections, and the use of genuine Traulsen commercial refrigerator parts will keep your refrigeration system running smoothly and extend its operational life.
