At React Power Solutions, we help operations managers keep critical power systems working without failure. If your diesel or natural gas generator fails to start, shows error codes, or doesn’t hold a load—our certified team is ready to rebuild, restore, and return your generator to service. This guide outlines what to expect during commercial generator repair, from diagnostics through delivery.
Initial Contact and Equipment Intake
Before repairs begin, we collect key information:
-
Generator make and model
-
Total hours of operation
-
Fuel type (diesel or natural gas)
-
Description of the problem or error message
After review, we schedule pickup or advise on transport to our Houston facility. We work with many nationwide clients and can coordinate logistics if needed.
React Power does not offer on-site service. All repairs are performed in-shop by our certified technicians using manufacturer-approved equipment and parts.
Step-by-Step Diagnostic Process
Visual Inspection
We start with a complete walkaround of the generator. Technicians look for:
-
Oil or coolant leaks
-
Cracked hoses or belts
-
Loose wiring or corroded terminals
-
Exhaust damage or discoloration
Visual inspection often identifies early failure points.
Fluid Level and Filter Checks
Next, we test and inspect:
-
Engine oil, fuel, and coolant levels
-
Fuel filters, oil filters, and air filters
Filters are replaced if clogged, damaged, or past service life. Clean fluids and filters prevent future damage and improve system performance.
Battery Testing
A dead or weak battery is one of the most common reasons a generator won’t start. We check:
-
Battery voltage and capacity
-
Terminal connection and corrosion
-
Cranking amps under load
Batteries that fail our test are replaced. We also clean terminals and secure all connections.
Fuel System Inspection
We test fuel quality, pressure, and flow. Common issues include:
-
Clogged fuel lines or filters
-
Injector wear
-
Contaminated fuel
For diesel units, we may recommend fuel polishing or sampling if the tank has sat unused for long periods.
Electrical System Testing
We check the control panel, wiring, and sensors. Key steps include:
-
Automatic transfer switch (ATS) testing
-
Insulation resistance testing
-
Verifying output voltage and frequency
-
Examining fuses and circuit breakers
Our team uses digital test equipment to detect irregularities in voltage or power delivery.
Cooling System Check
We inspect coolant level and concentration, then test:
-
Radiator function
-
Fan belt condition
-
Hoses and clamps
-
Thermostat operation
If needed, we flush the system and refill with fresh coolant.
Load Testing and Output Verification
Once all major systems are confirmed, we run a load test. This simulates real operating conditions.
We monitor:
-
Generator startup sequence
-
Load pickup and recovery
-
Voltage stability
-
Engine temperature
Load testing confirms the unit is safe to return to service. If output fluctuates or drops, we conduct further repairs before sign-off.
