Stop a Rising Reefer Temperature Before It Costs You the Load
Right now you're watching the display climb. Thirty four degrees. Thirty six. Thirty eight. You already called dispatch once and you're about to call again. The receiver's delivery window is closing and you don't have an answer for them yet.
Tell us your location, unit brand, set point and current reading — we load the truck before the tech leaves.
Picture the gauge holding steady at your set point again. The unit running clean and quiet. You pull into the dock on time with a clean temperature log and nobody asking questions about the load.
Getting from where you are to that second picture usually takes one visit from a mobile tech who knows reefer units. A rising temperature is almost always one of these: a refrigerant leak, a failing compressor, a blocked airflow path from a dirty coil or bad fan, or a sensor telling the unit the wrong story about the box temperature. Our tech pulls up with the gauges and parts to check all of it on site.
Common Causes We Find
- Slow refrigerant leak at a fitting or coil
- Condenser coil blocked with dirt or debris
- Evaporator fan running slow or not at all
- Faulty discharge air sensor
- Worn belt slipping under load
Local Conditions That Make It Worse
Dallas heat is brutal on a reefer that's already running weak. A unit that holds temperature fine in March can start climbing fast once summer sets in and the trailer sits loaded in a hot yard off I-20 or I-30. We see this pattern every year, so we know what to check first when the calendar says July.
Don't wait to see if it comes back down on its own. Call 972-703-4445 now with your current reading and set point. We'll send a tech to wherever you're parked in Dallas-Fort Worth.
