Frequently Asked Questions
Yes — 'board', 'computer', 'module' and 'controller' all name the same part: the APU's electronic control module (ECM). We repair Thermo King TriPac boards at component level, including the TriPac Evolution ECM, TriPac Rev 1.6, the standard TriPac controller, and the Evolution HMI display.
Just the board. Remove it from the plastic housing and ship only the board — do not send the plastic enclosure. This lowers your shipping cost and avoids damage in transit.
Inspect the rear side of the board for burn marks or visible PCB damage. Boards with burn marks have irreparable damage and cannot be serviced. If unsure, email photos of the rear of the board to support@dcfelectronic.com for a free pre-shipment assessment.
You pay to ship the unit to us; we cover standard ground return shipping (USPS/UPS/FedEx Ground) after repair. Overnight/expedited service or added return insurance is available at your request and cost.
We charge a small $150 diagnostic fee to cover the technician's time. You can choose to have it returned or we can scrap it for you (waiving the fee).
Yes! We repair it, but the client is responsible for the HMI plastic case.
