It’s a given: trailer breakdowns cost time and money; they can also cause claims and/or additional charges incurred on the carrier. Most of the time, trailer breakdowns can be attributed to a lack of proper maintenance. The best way to prevent and deal with breakdowns is to look at the areas that are most susceptible to wear and tear and address any issues before heading out on the road.

For a reefer unit, some common areas where issues arise are:

  1. Discharge Pressure – if it is too high, this could be attributed to broken fan belts, defective battery, defective High Pressure Cutout Switch on the compressor, or wiring.
  2. Reefer Engine Performance – ensure the fuel system to the engine and the solenoids are all in good operating order and that the fuel system to the engine is not plugged or has air in it. Check the inline fuel filter as well to make sure it is clean and operating as designed.
  3. Chutes – make sure there are no tears and that the chutes are properly attached so that air can flow through the unit.
  4. Unit Calibration – make sure the reefer unit has been calibrated according to the manufacturer’s recommendation; this will ensure that the temperature on the set point is accurate and will reduce exposure to claims or additional charges.

Remember to check these areas regularly to prevent a trailer breakdown and ensure that your unit is operating at peak condition. Also remember to refer to the manufacturers suggested maintenance schedule.
