Why Temperature Control Matters
Your Thermo King controller isn't just a component — it's a critical part of your fleet. Our repair ensures it functions to OEM specifications.
Malfunctioning controllers can cause temperature excursions that violate FDA and FSMA regulations
A single controller failure can destroy an entire load worth thousands of dollars
Repeated temperature issues damage customer relationships and affect rates
We test every repaired controller under simulated load conditions to ensure ±1°F temperature control to OEM specs. Your customers will never know your controller was repaired — only that their cargo arrived safely.
