Unexpected refrigeration failures are more than just an inconvenience; they're a direct threat to your cargo, your schedule, and your bottom line. When a critical sensor like the ungraded sensor in your Thermo King unit starts providing erratic data, the entire system's performance becomes unreliable. You might be experiencing inconsistent temperature control, unexplained system shutdowns, or frustrating diagnostic trouble codes that are hard to pin down. This lack of precision can lead to spoilage of sensitive goods and costly, unscheduled downtime on the road.

The root of this problem is often a failed or failing sensor that can't provide the accurate feedback the unit's controller needs to operate efficiently. Using non-genuine or aftermarket replacements can sometimes compound the issue, leading to a cycle of repeated failures and repairs.

The solution is to restore your system's integrity with a component you can trust: the Thermo King Ungraded Sensor (40-975 / 40-872). This isn't a generic imitation; it's an Original OEM Replacement part designed and manufactured to Thermo King's exact specifications.
