Refrigerated trailers, or “reefers,” are the backbone of transporting temperature-sensitive goods like fresh produce, frozen foods, and pharmaceuticals. A single breakdown can lead to spoiled cargo, costly delays, and unhappy customers. That’s why regular maintenance is non-negotiable for trucking companies, logistics managers, and drivers who rely on these units.
At Setpoint Reefer Service, we specialize in keeping your refrigerated trailers in top shape. In this post, we’ll share practical preventive maintenance tips to help you avoid breakdowns and extend the life of your reefer.
Why Maintenance Matters: Common Issues with Reefers
Refrigerated trailers face unique challenges due to their cooling systems and constant exposure to the elements. Here are some common problems that can arise without proper care:
- Refrigerant Leaks: Low refrigerant levels can impair cooling, putting your cargo at risk.
- Faulty Seals: Worn door seals allow warm air to seep in, forcing the unit to work harder.
- Temperature Control Failures: Malfunctioning thermostats or sensors can lead to inconsistent temperatures.
- Compressor Wear: Overuse or neglect can cause this critical component to fail.
Ignoring these issues can result in emergency repairs, downtime, and even regulatory fines if cargo temperatures fall outside acceptable ranges. Preventive maintenance is your first line of defense.
Your Preventive Maintenance Checklist
Incorporate these steps into your routine to keep your refrigerated trailer running smoothly:
1. Check Refrigerant Levels Regularly
Low refrigerant is a leading cause of cooling issues. Inspect for leaks and top off levels as needed. If you’re unsure how to do this safely, our team at Setpoint Reefer Service can handle it for you.
2. Inspect Door Seals and Gaskets
Worn or damaged seals compromise temperature control. Check for cracks, tears, or gaps, and replace them promptly to maintain a tight seal.
3. Test Temperature Controls
Before each trip, verify that the thermostat and sensors are working correctly. Run a pre-cooling cycle to ensure the unit reaches and maintains the desired temperature.
4. Clean the Condenser and Evaporator Coils
Dirt and debris can reduce airflow and efficiency. Use a soft brush or compressed air to clean these components monthly or as needed.
5. Monitor Compressor Performance
Listen for unusual noises or vibrations, which could signal wear. Schedule professional servicing if you suspect an issue—our experts can diagnose and repair compressors quickly.
6. Inspect Electrical Connections
Loose or corroded wiring can disrupt power to the cooling system. Check connections and address any issues before they escalate.
The Benefits of Staying Proactive
Investing time in preventive maintenance pays off in multiple ways:
- Reduced Downtime: Catch problems early to avoid roadside breakdowns.
- Lower Repair Costs: Small fixes now prevent expensive overhauls later.
- Regulatory Compliance: Maintain consistent temperatures to meet industry standards.
- Longer Equipment Life: Well-maintained reefers last longer, saving you money on replacements.
