Generator repair
Generator repair starts with the symptom, the exact model and the controller—not a parts cannon.
Use this guide to organize the problem, capture useful information, decide whether you need a repair service call, and understand when the work has crossed into electrical, fuel-system or manufacturer-authorized territory.
No crank / weak crank
Often points toward starting-power or connection issues, but exact diagnosis depends on the model and controller status.
Starts then shuts down
Protective shutdowns, engine conditions, fuel issues and controller faults can all produce this symptom.
Alarm or error code
Record the exact code before clearing it. Model-specific documentation is often the fastest path to a useful diagnosis.
Runs but does not supply the house
Transfer-switch and electrical-system issues require professional diagnosis because hazardous voltage may be present.
Before you call
Give the generator repair company a useful starting point.
- Brand and exact model number
- Serial number if accessible without disassembly
- Exact alarm/error code
- Whether the engine cranks
- Whether the outage is active
- Last maintenance date and approximate run hours
- Any recent installation, fuel or electrical work
What kind of service?
Repair, maintenance and installation are different calls.
If the generator is operating normally and simply due for scheduled service, start with maintenance. If you are replacing or adding a standby system, start with installation. If there is a fault, shutdown, no-start or transfer problem, use the repair path and preserve the controller message before service arrives.
