Common Refrigerated Truck Issues and How to Troubleshoot Them

Refrigerated trucks, commonly referred to as reefers, play a crucial role in the transportation industry by guaranteeing the delivery of perishable goods in fresh and intact condition. However, like any other vehicle, reefers are prone to technical issues that can disrupt the smooth operation of the cooling system. 

In this blog, we will explore four common refrigerated truck issues that drivers and fleet owners encounter, along with troubleshooting tips to address them effectively. Whether you’re in Laredo, TX, or any other location, understanding these problems can help you perform quick fixes and minimize costly downtime.

4 Common Refrigerated Truck Issues and Their Solutions

Following are the common refrigerated truck issues and their solutions:

Issue #1: Refrigerant Leaks

One of the most common issues faced by refrigerated trucks is refrigerant leaks. Refrigerant is responsible for cooling the cargo area, and a leak can lead to a gradual loss of cooling performance. Detecting the exact location of the leak can be challenging, but it’s crucial to address it promptly to avoid spoilage of perishable goods.


If you suspect a refrigerant leak, seek professional reefer repair assistance immediately. Technicians have the expertise and specialized tools to identify and repair leaks efficiently. Regular maintenance and leak checks can help prevent this issue in the future.

Issue #2: Inconsistent Temperature Control

Another prevalent problem is inconsistent temperature control inside the reefer. Fluctuations in temperature can lead to uneven cooling, resulting in spoiled products or compromised freshness.

Start by inspecting the thermostat settings and making sure they are calibrated correctly. Clean the temperature sensors and ensure they are not obstructed by cargo. Check the door seals for any damage or debris that may cause air leakage. If the issue persists, consult a professional for in-depth reefer repair to assess the system’s overall health.

Issue #3: Electrical Problems

Electrical malfunctions can disrupt various components of the refrigerated truck’s cooling system. From faulty wiring to blown fuses, these issues can halt the cooling process and leave you with a truckload of potential losses.


Begin by examining the fuse box and replacing any blown fuses. Inspect the wiring for signs of wear or damage and repair or replace as necessary. Sometimes, the problem may lie in the battery, so ensure it’s in good condition and properly charged. If the issue persists, enlist the expertise of a qualified technician familiar with truck repair in Laredo, TX, or your local area.

Issue #4: Frozen Evaporator Coils

Frozen evaporator coils commonly occur when the reefer operates for extended periods. This build-up of ice obstructs the airflow, leading to insufficient cooling and potential mechanical damage.

First, turn off the reefer unit and allow it to defrost naturally. Inspect the evaporator coils for damage and clean them thoroughly to remove any ice buildup. Regularly cleaning the coils and maintaining proper airflow can help prevent this issue.


As a refrigerated truck owner or driver, understanding these common issues and their troubleshooting steps can save you valuable time and money. Remember to prioritize regular maintenance and inspections to keep your reefer in top-notch condition.

If you operate in Laredo, TX, or the surrounding areas, finding a reliable truck repair shop in Laredo, TX, with experienced technicians can make all the difference in ensuring the longevity and efficiency of your refrigerated truck. Stay vigilant, and a well-maintained reefer will keep your perishable cargo fresh and your business thriving.
