Generator repair
A generator that failed during an outage usually has a findable cause. Here's what generator repair covers.
When a standby generator fails, it's usually because of something small: a dead starting battery, a tripped breaker, a fuel valve that was left closed, low oil, or a controller fault. Some problems are bigger, like a failed transfer switch, a damaged engine or flood water in the enclosure. A generator technician can read the controller's fault history, test the parts, and tell you what it'll take to get it back in service.
Common problems
- Won't start. Weak battery, low oil shutdown, fuel supply, spark plugs or controller settings
- Starts but the house stays dark. Transfer switch, generator breaker or wiring problems
- Shuts down under load. Too much load, fuel pressure that drops off, or overheating
- Fault codes or warning lights. The controller's log tells the technician where to start
- Storm damage. Debris, wind-blown water, or flood water in the enclosure
What should I do if my generator fails during an outage?
- Check the controller display for a fault code and write it down.
- Check that the generator's main breaker is on and the fuel valve is open.
- Don't open the enclosure or the transfer switch while it may be energized.
- Call a generator company with the make, model and fault code.
If you switch to a portable generator in the meantime, run it outdoors, more than 20 feet from the house's windows, doors and vents, and keep a battery-powered CO alarm inside, as CDC advises.
Was the generator under water?
Don't run a generator that was in flood water until it's been checked. Water can get into the engine, the alternator, the controller and the wiring. The same goes for a transfer switch or panel that took on water.
Repair or replace?
It depends on the age of the unit, what failed, whether parts are available and what the warranty covers. Ask the technician to explain the options in writing.
The generator company prices the job after looking at your house, your electrical panel and your fuel supply. We don't quote prices, and any number given over the phone before a site visit is only a rough starting point.

Common questions
Why didn't my generator start when the power went out?
Common causes are a dead battery, low oil, a closed fuel valve, a tripped breaker or a controller fault. A technician can read the fault history and find out.
Can you fix any brand of generator?
We don't do repairs ourselves. We connect you with an independent company; ask them which brands they service and whether they can get parts.
