Generator Repairs
Generator Repair Services Brisbane
When a standby generator fails, identifying and repairing the fault is essential to restoring your organisation’s backup power supply. Genergy Australia provides professional generator repairs across Brisbane and South East Queensland, helping businesses diagnose faults, repair equipment and minimise operational downtime.
Established in 1995, our family-owned business has more than 30 years of experience supporting commercial and industrial generators. Our qualified electricians and diesel mechanics provide generator repair services for hospitals, correctional centres, government facilities, high-rises, warehouses and distribution centres.
Based in Acacia Ridge, we carry out generator repairs in Brisbane, Gold Coast, Sunshine Coast and surrounding South East Queensland areas, extending north to Noosa, west to Toowoomba and south to the NSW border.
Commercial Generator Repairs and Fault Diagnosis
At Genergy Australia, our skilled technicians have the expertise to diagnose and repair mechanical, electrical and control-system faults across a wide range of diesel generators.
Rather than engaging separate electrical and mechanical contractors, your business can access both services through one experienced team.
Our generator repair capabilities cover:
- Diesel engines, including mechanical faults and component replacement
- Alternators and electrical output systems
- Generator controllers and associated electrical equipment
- Automatic transfer switches and changeover systems
- Fuel transfer pumps, level switches and related components
- Battery chargers, starter motors and automatic voltage regulators
- Diesel storage systems, fuel tanks and fuel level gauges
- Generator canopies and associated equipment
Whether your generator has developed an intermittent malfunction or experienced a complete breakdown, our technicians can identify the problem and recommend appropriate repairs.
Common Generator Faults We Repair
Generator issues can develop even when equipment has not been used regularly. Our team investigates common signs of mechanical and electrical faults, including:
Generator Won't Start
A generator that fails to start may have a flat battery, faulty starter motor, fuel supply problem or controller malfunction. Our technicians assess the starting system to identify the underlying fault and determine which repairs are needed.
Generator Runs but Produces No Power
If your generator is running but not supplying electricity, the problem may involve the alternator, automatic voltage regulator, circuit protection or loose electrical connections. We inspect the relevant components to identify and repair the fault.
Generator Surging or Running Unevenly
Changes in engine speed or frequency can indicate fuel delivery problems, governor faults or control-system issues. Our technicians investigate these symptoms to help restore stable generator operation.
Overheating and Unexpected Shutdowns
Overheating can cause a generator to shut down before it can supply the required power. Possible causes include cooling-system faults, low coolant levels, restricted airflow or malfunctioning sensors. We assess the equipment before carrying out the necessary repairs.
Automatic Transfer Switch Not Working
During power outages, an automatic transfer switch should transfer the electrical load from mains power to the standby generator. If this doesn’t happen, our qualified electricians can inspect the transfer system, controls and associated electrical components.
Generator Set Repairs and Replacement Parts
Our Brisbane based team has extensive experience working with generator sets, or GenSets, ranging from smaller 6kVA units to complex 2250kVA installations with automatic synchronisation and shared-load capabilities.
We work with established engine brands, including Cummins, Volvo, Detroit, John Deere, Perkins, Dorman, Caterpillar, Mitsubishi and Kubota.
Our technicians also repair and troubleshoot generator control systems, including DSE, ComAp, PowerWizard, Omron, Woodward, SiTEC, PowerCommand and Bernini.
To support efficient repairs, we maintain a network of Queensland suppliers and stock commonly required components at our Acacia Ridge warehouse. Our service vehicles also carry essential parts and diagnostic equipment to assist technicians on site.
