microFUSION Power Controller Repair Services

The microFUSION series (commonly found in industrial heating, ovens, extruders, thermal processes, and other SCR power-control applications) is built for precise power regulation—but failures happen from heat stress, line events, aging components, and I/O damage. Control System Labs repairs microFUSION power controllers to restore stable output, accurate control, and reliable operation—often faster and more cost-effective than replacement.

What We Service in the microFUSION Series

• SCR power controllers (phase-angle / power regulation configurations)
• Firing and control electronics (gate drive and control sections)
• I/O and interface issues (control signals, feedback, and communication-related faults)
• Power section problems (shorted devices, damaged protection components, thermal failure points)

Common Symptoms We Fix

• No output / partial output
• Intermittent operation or nuisance trips
• Input/output faults (control signal not responding, unstable control)
• Power supply failures or blown components after line events
• Overheating / thermal damage
