Dana Kowalski - Industrial Controls & VFD Specialist

Dana Kowalski has 14 years of experience in industrial maintenance and controls engineering. He holds the Certified Automation Professional (CAP) credential and is a certified Allen-Bradley and Siemens VFD technician.

His career spans manufacturing, food processing, and water treatment facilities, giving him broad exposure to PLCs, variable frequency drives, CNC equipment, and industrial automation systems used across different industries.

Dana writes error code guides focused on fault-level diagnosis that eliminates trial-and-error parts replacement. Rather than listing a shotgun approach of “try replacing this, then try replacing that,” his guides identify the specific measurement or test that confirms the root cause.
