Unexpected temperature fluctuations, unexplained system shutdowns, and costly cargo spoilage—these are the nightmares that keep fleet managers and transport refrigeration technicians awake at night. When a refrigeration unit on a truck, trailer, or shipping container fails, it's not just an inconvenience; it's a direct threat to your bottom line and your reputation for reliable, temperature-controlled transport. Often, the culprit behind these erratic behaviors is a small but critical component: a failing sensor.

These sensors are the nerve center of your Thermo King unit, constantly monitoring conditions and feeding vital data to the control system. When they malfunction, the entire system is flying blind, leading to inefficient cooling, excessive fuel consumption, and ultimately, a complete breakdown. Sourcing the right replacement part quickly is paramount to minimizing downtime and protecting your valuable load.
