Control Concepts provides repair and maintenance services for Eaton AC drives and legacy Cutler-Hammer drive and motor control equipment. Many legacy Cutler-Hammer products remain in service today, and our technicians help keep those systems operating through diagnostics, repair, replacement, and support. Eaton’s current controls and drives portfolio includes variable frequency drives and soft starters used across industrial, HVAC, water, and OEM applications.
Who Is Eaton / Cutler-Hammer?
Eaton is a global power management company serving industrial, commercial, and utility markets. Many legacy motor control and drive products originally sold under the Cutler-Hammer name are now associated with Eaton, while Cutler-Hammer branded equipment remains widely used in existing facilities and installed systems.
Control Concepts services both current Eaton AC drives and legacy Cutler-Hammer equipment still in operation.

Common Eaton / Cutler-Hammer Drive Issue
Some common Eaton and legacy Cutler-Hammer drive issues we address include:
- Drive does not run the motor
- Blown fuses or tripped breakers
- Loose or damaged connections
- Non-functional cooling fans
- Software or programming problems
- Circuit board failures
Most drive failures can be avoided through preventive maintenance, including routine inspections, testing, and early fault detection.
The Control Concepts Repair Process
Inspection
We inspect the drive, control boards, terminals, and power connections for loose, worn, or heat-damaged conditions caused by heat cycling, vibration, or improper torque practices.
Electrical Testing
We perform diode and IGBT testing on the input and output power sections before applying power to help prevent further damage.
Controlled Power-Up
The unit is powered up gradually while monitoring voltage, current draw, and output frequency until rated input voltage is reached.
Functional Testing
We back up existing parameters when possible and test the drive through basic jog and operational functions, verifying output voltage, current ratings, and motor rotation.
Final Verification
Each Eaton or Cutler-Hammer drive is fully tested to confirm proper operation before returning it to service.
Preventive Maintenance Recommendations
To reduce failures and extend equipment life, we recommend:
Keeping drives and control equipment free of dust and debris
Dust buildup can trap heat and interfere with cooling and internal components.
Ensuring proper ventilation
Adequate airflow helps prevent overheating and supports reliable drive operation.
Keeping equipment dry and protected from moisture
Moisture can damage electrical components and lead to shorts, corrosion, or premature failure.
Inspecting terminals and connections regularly
Routine checks can help identify loose or heat-damaged connections before they cause downtime.
Scheduling periodic testing and inspection
Regular inspection of power sections, wiring, and operating condition can help catch problems early and reduce unexpected failures.
Preventive maintenance plays a key role in reducing unplanned downtime and extending equipment life.
