This article explains what Service Mode does on Next Generation air-cooled home standby generators with a PowerZone 200 controller, and how to turn Service Mode off safely. It clarifies that Service Mode prevents remote start/stop, and also disables Mobile Link notifications and firmware over-the-air updates, but it does not change the generator’s AUTO/OFF/MANUAL setting. It also confirms your home is still protected during an outage if the generator is in AUTO. The steps walk you through disabling Service Mode at the generator by pressing the SERVICE button so the blue light turns off, supporting safe, reliable backup power.
