Conair A‑015840 107‑262‑01‑01 is a CPU/processor board used in Conair’s industrial dryer control systems, typically housing an 80C31 microcontroller and LED status indicators. Common failure points on this class of boards include burned or cracked ICs, damaged power‑plane traces, and failed voltage regulator components; the board often shows symptoms such as no LED indication, erratic cycle counts, or complete loss of communication with the main controller. First‑check diagnostics: verify 12 V/5 V supply rails at the board’s input connectors, inspect for visible burn marks or loose solder on the CPU and voltage regulator packages, and run a continuity test across the power plane to ensure no open traces; if available, review any stored error logs from the dryer controller for related fault codes.[oss-gpt-20b]
