Advanced Expertise

Working with a team that specializes in diagnosing and repairing controls means quicker turnaround times at a fair price. We use advanced diagnostics techniques to quickly find the cause of problems in every type of equipment including motor speed controls, operator interfaces, temperature controls and PLCs. We are equipped with extensive testing capabilities and test every control using a four-level process to find the right balance between repair speed and accuracy. We have collected and maintained thousands of pages of equipment documentation, drawings, user manuals, and equipment diagrams. This allows us to more efficiently repair items that our competitors cannot. Our technicians and engineers are not just good; they are the best in the industry and we are proud to stand behind every single repair with a two-year warranty.  

The Benefits of High-Quality Control Repairs

Finding a repair shop might be easy. Finding a shop that you can trust to keep your equipment working as fast and as economically as possible isn’t, but you’re in the right place now. Our combined expertise and experience allow us to provide the highest quality repairs in the business, and provide that service fast and at a fair price.


Testing Capabilities


Diagnosing and repairing your controls is only the beginning. We also test each control on one of the tens of thousands of test fixtures in our facility. The four-level testing process we use will strike the right balance between fast service and accurate repairs. Of course, we also stand behind every single repair we make and back it with a two-year warranty so you can feel confident in our work.

Extensive Experience


We have completed more than 100,000 repairs for more than 10,000 customers over the last 50 years. Our engineers and technicians have an average of 30 years of experience in virtually every industry. With a crew as experienced as ours, it would be tricky to find something we’ve never seen before. Of course, we’re always up for a challenge if you think you have a stumper!

Raw Materials


We know how important fast turn around time is for your repairs. To address many lead-time procurement issues, we maintain an inventory of over 30,000 components and raw materials. A portion of our inventory  is actually considered obsolete in the market. That allows us to repair your older equipment that our competitors say is not fixable.  Maintaining so much inventory is  critical to meeting our commitment to support our customers. 

Committed to our Customers


We don’t want to simply repair your controls and drop them off for shipping. Instead, we like to build relationships with our customers so we can work side-by-side to ensure your equipment is working as efficiently as possible. We take our two-year repair warranty personally: we want to learn all about your setup and operations to be your go-to repair shop.

Simplified Repair Process

We work to make the repair process as easy as possible. Start by searching our database for the part, select the items you need to be repaired, add them to your request, and complete the RMA form. If you can’t find the items you need, no problem! Just include your control’s information on the RMA form. Lastly, print the RMA form, box it up with your items for repair, and send them to us for a free repair assessment. Once we’ve completed the assessment, we’ll provide a personalized quote if the item you needed to be repaired was not available at the start of the process. We’ll also send you an Authorization to Repair. Once you provide authorization, you’ll receive your repaired and tested part back in about 10 business days, complete with a two-year warranty on all parts and labor issues. Ready to get started? Head over to our database and you’ll be done in minutes.
