Signs Your Generator Needs Repair

Even the most reliable system can develop issues over time. Addressing early warning signs can prevent major breakdowns and expensive repairs later on. Look out for these common indicators:

• Frequent starting problems: If your unit struggles to start, it may need immediate inspection.
• Inconsistent power output: Flickering lights or uneven performance indicate possible wiring or voltage issues.
• Visible leaks: Oil or coolant leaks can signal mechanical damage that requires prompt generator repair.
• Strange noises or vibrations: Unusual sounds often point to worn-out parts or internal imbalances.
• Warning lights or fault codes: Built-in alerts are your system’s way of asking for generator maintenance.
• Increased fuel consumption: A sudden rise in fuel use suggests your unit is working harder than it should.
