The Diagnostic and Testing Process

We have all the tools and equipment to diagnose and repair your control including more than 10,000 test fixtures, motor test stands, a thermal chamber to test controls at hot and cold, and an x-ray machine to perform in-depth analyses. We also test each control following repair to be sure that all defects have been identified and fixed. We utilize 4 categories of testing and each unit receives an individualized test plan that is appropriate for that part to ensure a fast and affordable repair. Plus, we stand behind every single control repair with a two year warranty on parts and labor issues.
