What to Do When Reefer Temperature Rises
You notice the temperature climbing above your set point, and you're not sure if it's something small you can check yourself or something that needs a tech right away.
Tell us your location, unit brand, set point and current reading — we load the truck before the tech leaves.
You know exactly what to check first, and if it's beyond a quick look, you've got a tech already headed your way instead of losing another hour guessing.
Here's the order to check things in.
Step 1: Confirm the Set Point
Make sure the set point wasn't accidentally changed. It happens more than you'd think, especially after a driver switch.
Step 2: Check the Doors and Seals
A door that isn't fully latched, or a torn seal, lets warm air in constantly and the unit can't keep up no matter how hard it runs.
Step 3: Listen to the Unit
A unit that sounds like it's running but isn't cycling the compressor the way it normally does may have a clutch or electrical problem.
Step 4: Check for Obvious Airflow Blockage
Look at the condenser coil from outside the trailer. A coil packed with dirt, leaves, or road debris blocks the airflow the unit needs to release heat.
When to Call for Help
If the doors are sealed, the set point is right, and the coil looks clear but the temperature keeps climbing, that points to something internal like a refrigerant leak, a failing compressor, or a sensor problem. That's not something to keep watching and hoping it corrects itself.
Call 972-703-4445 now and tell us your set point and current reading. We'll send a tech to your location anywhere in Dallas-Fort Worth.
