Common Load Bank Issues We Repair
These are the most frequent problems we diagnose and repair. If your load bank is showing any of these symptoms, contact us for an assessment.
Resistor Element Failure
Symptoms
- Inconsistent load readings across steps
- Visible hot spots or discoloration on elements
- Burning smell during operation
- Reduced maximum load capacity
Our Solution
We test each resistor element individually, replace failed units with OEM-spec components, and verify full load capacity before returning the unit to service.
Control System Problems
Symptoms
- Load steps not engaging properly
- Erratic display readings or error codes
- Communication faults with external controllers
- Intermittent automatic mode failures
Our Solution
Our technicians diagnose control board faults at the component level, repair or replace affected circuits, and recalibrate the entire control system.
Cooling System Issues
Symptoms
- Overheating warnings during extended tests
- Excessive noise from fan assemblies
- Uneven airflow across resistor banks
- Fan motor failure or reduced RPM
Our Solution
We service fan motors, clean airflow paths, replace worn bearings, and verify thermal management performance under full load conditions.
Contactor Problems
Symptoms
- Audible chattering from contactor assemblies
- Load steps sticking on or failing to engage
- Visible arc damage on contactor contacts
- Delayed response when switching load steps
Our Solution
We rebuild or replace worn contactors, inspect arc suppression systems, and verify reliable switching across all load steps.
Our Repair Process
Every load bank repair follows a structured process to ensure thorough diagnosis and reliable results.
Initial Assessment
We review your load bank’s service history, document reported symptoms, and perform a visual inspection to identify obvious damage or wear before powering up the unit.
Diagnostic Testing
Using specialized test equipment, we verify each load step, measure resistor element values, test control circuits, and log performance data to pinpoint every fault.
Professional Repair
Our technicians replace failed components with OEM-specification parts, repair wiring and connections, and address every issue identified during diagnostics.
Testing & Calibration
After repair, we run the load bank through its full range, calibrate metering instruments, verify control system accuracy, and document final test results.
Why Load Bank Maintenance Matters
Accurate Testing
A properly calibrated load bank ensures your generator testing produces reliable data. Inaccurate load readings can mask generator problems, leading to failures when you need backup power most.
Equipment Longevity
Regular maintenance extends the service life of your load bank by catching minor issues before they become costly failures. Preventive care protects your investment and avoids unplanned downtime.
Safety Compliance
Load banks operate at high power levels where equipment faults create serious safety risks. Well-maintained units with verified safety interlocks protect your technicians and facility.
