Your reefer trailer and reefer unit may be separate, but because one is installed on the other, it can be challenging to determine whether a problem is with the unit or the trailer.

In many cases, you should hope that the problem is with the trailer. If it is, you might be able to fix the issue with a little elbow grease. However, if the problem is with your reefer unit, then you might need to invest in an entirely new reefer trailer.

But how do you know if you need a new reefer unit, reefer trailer, or both?

Signs it’s time for a new reefer unit

It’s easier to tell when it’s time to invest in a new reefer unit because it acts as an air conditioning unit for your reefer trailer. Common signs that your reefer unit needs to be replaced include fluid leaks, condenser issues, and sensor malfunctions.

Coolant leaks are a serious problem because they can keep your trailer from effectively cooling. They can also leak onto the products you’re carrying in your trailer.

Sensor malfunctions are also problematic because they can cause incorrect temperature readings inside the trailer. This can ruin the products inside the trailer or cause the reefer unit to overwork itself.

Routine maintenance is key to ensuring your reefer unit stays in good working condition. But if these problems continue even after your reefer unit has been serviced, you may need to replace the unit.

Signs it’s time for a new reefer trailer

Issues with your reefer trailer are typically more structural compared to the malfunctions of a broken reefer unit. For instance, if your reefer trailer doesn’t seem to stay cold despite the fact that the reefer unit is working efficiently, it could be a sign that there’s a draft.

Inspect your trailer for cracks or sealant issues. You may be having temperature regulation issues because the doors won’t properly seal.
