Introduction
Soft starters are essential for controlling motor acceleration, minimizing mechanical stress, and improving energy efficiency—especially in pumps, compressors, conveyors, and HVAC systems. But when a soft starter fails, it can cause sudden shutdowns, costly repairs, or even motor damage. Cause: Peripheral circuit failure or the operation terminal on the control board is. Scroll to the bottom of any page to find a sun or moon icon to turn dark mode on or off! Sounds like you either have a bad start capacitor in the Easystart or the SCR/relay/fuse in Easystart that makes the start capacitor connection to compressor start winding connection during spin up time is bad. Every EasyStart is tested on a compressor before it leaves Micro-Air to ensure it will work when delivered.
