Reefer Trailer Repair
A reefer alarm with a loaded trailer is a clock you can't ignore. Beyond the standard trailer systems, the Thermo King or Carrier unit itself can usually be diagnosed and repaired roadside.
If an eligible approved provider is on duty and available, it may respond with a price and ETA. Response and arrival are not guaranteed.
Common reefer (refrigerated) trailer problems
Thermo King and Carrier units throw alarm codes for low refrigerant, high discharge pressure, fuel, and sensor faults. Note the alarm number — it speeds diagnosis.
Many roadside reefer faults are belts, temperature/pressure sensors, fuel starvation, or a refrigerant top-off — fixable on-site by a unit tech.
Lights, ABS, airlines, brakes, tires, and landing gear fail on reefers like any van — plus the reefer fuel tank and mounting.
Damaged air chutes and bulkheads cause uneven temps and load claims even when the unit runs fine.
What a mobile tech fixes roadside
Mobile refrigeration techs (Thermo King / Carrier) handle most roadside reefer faults — belts, sensors, fuel, refrigerant, and diagnostics — plus the standard trailer items (lights, brakes, airlines, tires). Protect the load: pre-cool, keep doors closed, and dispatch immediately.
What usually needs a shop
Compressor replacement, major refrigerant system work, evaporator/condenser coil replacement, and trailer structural repairs typically need a shop.
