Your reefer just stopped cooling. The emergency is the load, not the trailer.
When a reefer stops cooling, the load is the emergency, not the trailer. Keep the doors shut, note the setpoint and current box temperature, check the unit's fuel and power connections, and call the load's owner early. A towing company can move the trailer fast; the refrigeration unit itself needs the manufacturer's service network.
The trailer is fine. The load is on a clock.
A reefer that stops cooling is a different kind of breakdown from everything else on this site. The tractor runs, the trailer rolls, nothing is blocking a lane — and it is still the most time-critical call there is, because the emergency is not mechanical. Behind the doors is freight with a temperature window written into the contract, and the moment the unit stopped, that window started closing.
So judge everything in the next hour against one question: does this protect the load's temperature, or spend it? Diagnosis is worth minutes. Keeping the doors shut is free. Opening the box to check on the product at every stop is how a repairable afternoon turns into a rejected load.
Five checks before you call anyone
- Doors stay shut. The cold already in the box is the only asset you have while the unit is down. A sealed, pre-cooled trailer holds its temperature for a long time; an opened one gives it up in minutes. Nobody looks at the freight until there is a plan.
- Check the reefer's own fuel. The unit runs on its own small diesel tank, separate from the tractor's, and an empty one is one of the most common causes of a warm trailer. Check the level by eye where you can rather than trusting the gauge.
- Read the unit's display. Modern units post fault codes and alarms on their own controller. Write down exactly what it says, along with the setpoint and the current box temperature — those numbers run every conversation that follows.
- Listen to what it is doing. Trying to start and dying points at fuel or the unit's battery. Running but not cooling points at the refrigeration side. Dead silence points at power or wiring — some of which is trailer-side and fixable.
- Look at the doors and seals. A unit that runs flat out while the box loses temperature may be fighting a torn gasket or a door that no longer latches square. That is a trailer fault, and trailer faults have roadside answers.
Know the window, and make the early call
Every reefer load has a temperature window, and the person who knows how much room is left in it is not you — it is the shipper or the load's owner. Frozen product in a well-sealed box has more time than fresh produce riding near its limit; a load that was properly pre-cooled has more than one that went on warm. None of that is visible from the driver's seat, which is why the call to the owner or broker goes out early, not after you have run out of your own ideas.
Early matters for a second reason: the decisions that follow are not yours to make. Whether the load can wait for a unit technician, whether the trailer moves to a repair point, whether the freight transfers to another trailer — those are the owner's calls, and every one of them goes better with more window left. Report the setpoint, the box temperature, when the unit stopped and what the display says, then do what they tell you.
Who fixes what — an honest boundary
Here is the part a towing company should say plainly: we do not repair refrigeration units. The unit on the nose of the trailer — its diesel engine, compressor and controller — is a sealed specialist system, and when it fails it needs the manufacturer's service network, not a roadside truck with good intentions. Our trailer repair page says exactly this, and it is worth repeating here, because a company that will guess at a reefer plant is gambling with someone else's load.
What we do repair is the trailer underneath it: lights, wiring, air lines, brakes, landing gear, doors, seals and tires, roadside, 24 hours a day. And the sorting between the two is genuinely useful work — describe what the unit is doing and what the display says, and we can usually tell you on the phone whether you have a unit problem for the dealer network or a trailer problem we can already be rolling toward. That one distinction stops you spending your window on the wrong phone calls.
When the fastest fix is a tow
When the unit needs the dealer, the question becomes where the trailer meets the technician — and often the fastest answer is bringing the trailer to the repair point rather than waiting for the repair point to come to it. Moving loaded trailers is exactly what our wreckers do: a loaded reefer tows as-is if the freight is secure and the trailer is roadworthy, the tractor does not have to stay with it, and the wreckers and the service truck run from the same Liberty yard, so one call covers whichever this turns out to be. If the real fault is the tractor rather than the unit, the same logic applies — the trailer does not have to wait. It can go on to another power unit or straight to a dock.
Two honest notes about our yard at 2751 Liberty Landing Rd. A trailer can stand there while decisions get made, but a reefer with a dead unit is not refrigerated storage and we will not pretend otherwise — we hold perishable freight only as long as its owner instructs, and no longer. If the right move is straight to the dealer's gate or to a cross-dock the owner has arranged, we would rather run it there directly. The load's clock does not stop because the trailer is parked somewhere convenient.

What this covers
Trailer repair
Most trailer faults do not stop a trailer moving. They stop it being legal to move, which is worse — the load sits while the paperwork says it cannot go anywhere.

A loaded tractor-trailer is not a bigger car. It needs a rated wrecker, a rated operator and a plan before anything gets hooked. That is what we send.
