Kuala Lumpur | February 25, 2026 — EKG M&E Sdn Bhd has successfully completed a specialized electronic repair for the HVAC infrastructure at Menara PNB. The technical intervention, conducted for Vantris Energy on Level 39, focused on the precision replacement of a faulty inverter board to restore high-performance climate control to the facility.
Scope of Work: Inverter PCB Replacement, Diagnostic Testing, and System Integration
The high-rise climate control system at Menara PNB Level 39 experienced a critical failure in the outdoor unit's power conversion stage. Diagnostic testing traced the fault to the inverter printed circuit board (PCB), which regulates motor speed and energy consumption. A malfunctioning board leads to total system lockout, necessitating an immediate replacement to maintain the workspace's operational environment.
Our specialized technicians executed a systematic electronic overhaul to ensure long-term stability:
Diagnostic & Access: The outdoor unit was safely isolated, and the main control housing was opened to access the internal electronic modular stack.
Precision PCB Replacement: The faulty inverter board was decommissioned and replaced with a brand-new, high-specification inverter PCB. Our team ensured all multi-pin connectors and thermal sensors were precisely seated to prevent future communication errors.
Wiring & Connection Integrity: All associated wiring harnesses and terminal connections were inspected for signs of heat stress or oxidation. Protective conduits were verified to ensure the delicate electronic components remain shielded from environmental factors.
System Testing: Following the hardware installation, the system underwent a controlled power-up and sequence test to verify that the new inverter board was communicating correctly with the compressor and indoor units.
Restored System Intelligence: The new inverter board allows for precise modulation of the HVAC system, ensuring the temperature on Level 39 remains stable even during peak heat hours.
Optimized Energy Consumption: By replacing the faulty board with a genuine, high-efficiency component, EKG has restored the system's ability to operate in energy-saving modes, reducing the overall carbon footprint for the floor.
Minimized Downtime: Our rapid response and diagnostic accuracy allowed Vantris Energy to resume normal operations with minimal disruption to their high-floor corporate environment.
