Generator Repair in Nigeria: Common Faults & Fair Prices (2026)
By NaijaArtisans Editorial Team · 5 min read · Updated June 2026
When the light goes and your gen won't start, you're at the mercy of whoever shows up. Knowing the common faults and their fair prices puts you back in control and stops a small repair turning into a big bill.
Common generator faults
- Won't start — often a dirty carburettor, bad plug, or stale fuel.
- Starts but no output — frequently a faulty AVR (voltage regulator).
- Smoking or overheating — oil, cooling or overload issues.
- Cuts off under load — fuel delivery or capacitor problems.
Fair repair prices (2026)
| General servicing (oil, plug, filter) | ₦5,000 – ₦15,000 |
| Carburettor clean / rebuild | ₦5,000 – ₦20,000 |
| AVR replacement | ₦6,000 – ₦25,000 |
| Capacitor replacement | ₦3,000 – ₦10,000 |
| Coil rewinding | ₦15,000 – ₦60,000 |
💡 Ask the technician to show you the faulty part they replaced. A trustworthy repairer has no problem doing this — and it stops the old trick of 'replacing' parts that were never bad.
