Hyundai Power Products Short Cycling / Incorrect Control Settings

Generator starts and stops repeatedly in short cycles without load

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Improper cool-down or stop delay settings, Faulty mains sensing causing false transfers, Intermittent remote stop signal

Safety first: Isolate ATS and avoid connecting sensitive loads until cycling is resolved.

Controller parameters: Check Hyundai controller run time, cool-down, and stop delay settings. Adjust to recommended values.
Mains sensing: Verify stable mains voltage and frequency. Intermittent mains can cause repeated start/stop cycles.
Remote wiring: Inspect remote start/stop wiring for intermittent shorts or loose connections.
