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.
Food Safety Compliance
Malfunctioning controllers can cause temperature excursions that violate FDA and FSMA regulations
Cargo Loss
A single controller failure can destroy an entire load worth thousands of dollars
Carrier Reputation
Repeated temperature issues damage customer relationships and affect rates
DCF Electronic Solution
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.
Frequently Asked Questions
Can I repair my controller or do I need a new one?
Most controller failures are repairable at the component level. Repair typically costs 40-60% less than a new controller and performs identically.
How do I know what model I have?
The model number is typically stamped on the controller label. Send us a photo or model number when starting a repair request, and we'll confirm compatibility.
Will you test the controller under load?
Yes, every repair includes comprehensive load testing that simulates real-world operating conditions, including cooling cycles, defrost, and sensor monitoring.
