Vitrifrigo (Secop BD electronic unit) error code 1 blink (Secop BD)
Battery-protection cut-out. Supply voltage at the Secop electronic unit is below the cut-out threshold (~10.5 V on Vitrifrigo). Almost always supply-side wiring rather than the unit itself.
What to check, and in what order, is in the app. The flow Secop BD Compressor Fault — Universal 5-Code Chart (Dometic CRX / Vitrifrigo / Whynter) walks this code step by step with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
