Cummins-Onan QD error code OVERLOAD (QD 3200)
Fault message: too many appliances are connected, or the inverter is defective. Rated output current is 26.7 amps. CAUTION Always perform stator check before replacing the invertor. Failure to do so will result in damage to the inverter. QD 3200 (HDZAA) - this inverter-type diesel shows TEXT MESSAGES on the remote Operator Panel display, not the blink codes of the QD 6000-10000 '(QD)' entries. Warning and fault messages, once cleared, cannot be retrieved; to clear faults turn the display off/on.
What to check, and in what order, is in the app. A step-by-step flow walks this code with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
