Your reefer container is the backbone of your cold chain operation. It ensures your perishable goods stay fresh, safe, and compliant throughout their journey. But like any high-performance machine, it needs regular care and timely maintenance.
Ignoring early warning signs can lead to breakdowns, cargo loss, and expensive repairs. At DSL Reefer Container, we help you stay ahead of problems before they cost you.
Here are 5 clear signs your reefer container needs maintenance—don’t ignore them!
🚨 1. Inconsistent Temperature Inside the Container
One of the most obvious signs something is wrong is temperature fluctuation. If your reefer can’t maintain a steady temperature—whether it’s -18°C for frozen foods or +5°C for pharmaceuticals—this could indicate:
- Faulty thermostat or temperature sensor
- Blocked airflow ducts
- Failing compressor or AC unit
✅ Tip: Always monitor temperature logs. If there’s any unexplained variation, it’s time for a check-up.
🧊 2. Ice Build-Up or Water Leakage
Ice inside the container or puddles of water can signal several issues:
- Poor airflow circulation
- Faulty defrost system
- Drain blockages
Ice buildup can block cooling pathways, causing uneven temperatures and putting your cargo at risk. Regular defrosting and inspection help avoid this.
🛑 3. Strange Noises or Vibrations from AC Unit
If your Thermo King or Carrier unit is making unusual sounds—clanking, rattling, or vibrating—it’s a red flag.
This could mean:
- Loose components
- Worn-out belts
- Fan or compressor malfunction
These issues, if ignored, can lead to complete unit failure. Book a service before it breaks down mid-transit.
🪫 4. High Fuel or Power Consumption
Is your reefer suddenly consuming more diesel or electric power?
That could mean:
- Reduced insulation efficiency
- AC unit overworking due to leaks or mechanical issues
- Poor airflow or blocked filters
At DSL, we often see energy spikes as an early sign of internal wear and tear. Regular inspections help reduce operational costs over time.
⚠️ 5. Warning Lights or System Error Codes
Modern reefer AC units from Carrier or Thermo King have diagnostic systems that display warning lights or error codes.
Never ignore these alerts.
They might be pointing to:
- Low refrigerant levels
- Electrical faults
- Sensor or software issues
A quick response can prevent serious breakdowns and extend your container’s lifespan.
