A reefer breakdown can threaten the load before the tractor or trailer becomes undriveable. This national guide focuses on refrigeration-unit problems—Thermo King and Carrier alarms, temperature drift, fuel or belt faults, sensor issues, and refrigerant-system symptoms—while separating those problems from ordinary trailer brakes, tires, lights, and air systems. Use the established directory routes below to find listed providers, then call one with the unit, alarm, temperature, and load details ready. Provider certification, parts, availability, and timing must be confirmed with that provider for the specific call.
Keep doors closed, follow the shipper's temperature-control procedure, and record set point, supply-air and return-air readings, alarm codes, fuel level, and the time the problem began. Do not claim that a load is safe based only on a display reading. The carrier, shipper, receiver, insurer, or food-safety process may require specific documentation and disposition decisions beyond the mechanical repair.
Roadside refrigeration technicians commonly diagnose no-start conditions, low battery voltage, blown fuses, damaged belts, fuel starvation, clogged filters, sensor faults, electrical connections, and alarm conditions. Refrigerant leaks, compressor damage, failed coils, or control-module problems may need specialized tools, parts, certification, and a shop. Have the unit make, model, serial number, alarm code, and recent service history ready when you call a provider.
A refrigerated trailer still has the same wheel ends, tires, brakes, suspension, lights, ABS wiring, air lines, doors, and landing gear as other trailers. A refrigeration technician may not carry heavy trailer-running-gear parts, and a mobile trailer mechanic may not be qualified or equipped for sealed refrigeration work. Describe both the temperature problem and any chassis or running-gear symptoms so you call the right kind of provider.
Ask whether the provider services the exact Thermo King or Carrier unit, performs mobile work at your location, has the required refrigerant credentials, and can source likely parts. Agree on timing, the diagnostic or call-out charge, labor terms, payment expectations, and how additional work will be authorized — directly with that provider. A directory listing or capability tag is not a guarantee of current certification, parts stock, or availability.
Major compressor, evaporator, condenser, structural, electrical-harness, or refrigerant-system work may require a dedicated refrigeration shop. A provider may also recommend a temporary load-protection step or transfer rather than an on-site repair. RoadService.app does not determine cargo disposition or guarantee temperature recovery; those decisions remain with the responsible carrier, shipper, receiver, and qualified service professionals.
These links lead to national editorial pages or existing service and location families. Local service pages are published only through the directory's provider-quality rules.
Mobile refrigeration technicians who service the relevant Thermo King or Carrier equipment handle many on-site alarm, belt, fuel, sensor, electrical, and diagnostic calls. Confirm current qualifications and equipment directly with the provider.
Have the unit make, model and serial number, every active alarm code, set point, supply and return temperatures, fuel level, load status, exact location, and whether the trailer also has tire, brake, electrical, or air-system damage ready before you call.
No. Many common faults can be diagnosed or repaired on site, but major refrigeration, compressor, coil, control, or structural work may require a shop and specific parts. The responding technician should explain the safe next step.
No. Directory coverage does not guarantee that a qualified provider is available for a specific unit, location, time, or repair. Confirm capability with the provider before approving work.
Search by location and service, then call a listed provider directly. Availability, price, and timing are set by that provider, not by RoadService.app.
