The GOMACO 051620250035 is a controller unit for the company’s G+ remote‑controlled paving machines, typically serving as the central electronics hub that interfaces with hydraulic valves and operator displays. Common failure points in this class include power supply board faults (over‑voltage, capacitor degradation), I/O module mis‑wiring or shorting, and firmware corruption leading to loss of communication with the G+ remote. Initial checks should verify the 48 V DC input voltage and continuity on the main power rails, inspect all connector pins for corrosion or bent contacts, and review any diagnostic codes displayed on the operator console or stored in the controller’s memory.[oss-gpt-20b]
