Field Failure Repair Case Studies
Case 1: GE Micro Drill Power Supply Failure
A GE Micro Drill system suffered complete power loss due to a faulty DS3800NPSE1D1E power supply card. Installing a new OEM-matched power supply card restored stable voltage distribution and full system operation.
Case 2: SCR Stack Overheating & Failure
Sustained SCR stack overheating led to drilling control instability, caused by a worn Comair Rotron blower fan. Replacing the faulty fan and damaged Westcode SCR pucks resolved thermal issues and restored power conversion.
Case 3: Drive Control Module Communication Error
A DS3820DCMB1D1C drive control module experienced signal communication errors, halting drill operation. Fitting a new DCM module eliminated signal faults and restored precise drill speed control.
