Usman A.

Usman’s strength lies in his cross-disciplinary electromechanical diagnostics. For refrigeration systems, he specializes in the safe handling and recovery of highly flammable R600a (isobutane), resizing capillary tubes to match new compressor loads, and clearing localized moisture restrictions using sweep charges. In laundry equipment, he uses tachometers to verify drum RPM and tests Brushless DC (BLDC) motor stators for phase-to-phase resistance.

Usman frequently resolves complex spin-cycle failures caused by faulty Hall effect sensors or degraded tub-centering suspension rods. He is adept at diagnosing pressure switch anomalies that lead to infinite-fill or ghost-draining issues across Dammam, Saihat, Safwa, and Tarout.
