Zeeshan T.
Component-Level PCB & Inverter Technician
DC Inverter ACs, Smart Refrigerators, Appliance Electronic Control Boards.
Diagnostic & Repair Methodology
Zeeshan bypasses the costly practice of simply replacing motherboards by repairing them at the micro-component level. Operating out of the PCB lab, he uses oscilloscopes and ESR meters to trace signal loss and test the capacitance of degraded capacitors. He is an expert in precision micro-soldering, routinely replacing blown Insulated-Gate Bipolar Transistors (IGBTs), bridge rectifiers, relays, and Metal-Oxide Varistors (MOVs) damaged by local power surges.
Advanced Field Problem Solving
Zeeshan specializes in diagnosing stubborn communication error codes (such as E1 or EE) between indoor and outdoor DC inverter splits. He is capable of reflashing corrupted EEPROMs on logic boards and repairing cold solder joints on high-vibration washing machine mainboards across Dammam, Khobar, Dhahran, and Qatif.
