Generator Won't Start or Won't Transfer Power?

Standby generators, transfer switches and portable-generator hookups

Generator running but the house is dark, or a burning smell at the transfer switch? Shut it down and call.

Quick answer

When a standby generator won't start, the cause is often the battery, fuel supply, an active alarm or the controller not being in AUTO. When it runs but the house has no power, the transfer switch or its connections are the usual suspects. Xlectrical's licensed electricians (Florida License EC 13014052) answer 24/7 from Sunrise and serve all of Broward County. The emergency service call is $299 and is applied toward the repair.

Fire, smoke or someone shocked? Call 911 first. Whole street dark? Report it to FPL at 1-800-4OUTAGE.

Do this right now

  1. Check the generator's controller for an alarm or fault code, and make sure it's set to AUTO, not OFF or MANUAL.
  2. Confirm fuel: the gas valve is open, or the propane tank has fuel.
  3. Check the generator's main breaker — it may have tripped.
  4. Never run a portable generator indoors, in a garage or near windows, and never plug it into a wall or dryer outlet.
  5. If it runs but the house has no power, or you hear clicking or smell burning at the transfer switch, shut the generator down and call 754-289-8993.

Standby generator won't start

  • Battery: the most common cause. Standby batteries age in South Florida heat and often fail on the day of the outage.
  • Fuel: a closed gas valve, low propane, or a gas supply that can't keep up.
  • Alarms: low oil, overcrank, overspeed or a service reminder can lock out the engine until it's cleared.
  • Controller set to OFF or MANUAL after maintenance or a storm-prep test.
  • Skipped maintenance: oil, filters and spark plugs that are past due.

Generator runs but the house has no power

The automatic transfer switch (ATS) is what moves your home from FPL power to the generator. If the generator runs but nothing comes on, the problem is usually the ATS — a failed relay or contactor, a tripped generator breaker, a loose or burned connection, or a control wire problem. These are electrical repairs and should be done by a licensed electrician.

Portable generators

A portable generator should connect to your home only through a generator interlock or manual transfer switch. Backfeeding through an outlet can energize FPL's lines and injure workers, and it can damage your home's wiring. Keep the generator outdoors and away from doors and windows to avoid carbon monoxide. See standby vs. portable generators in Florida.

What we do

  1. Read the controller history and alarms and check the battery, charger and generator breaker.
  2. Test the transfer switch, its contactor and connections under load.
  3. Repair electrical faults and coordinate with your generator dealer or gas contractor for engine or fuel issues.
  4. Run a load test so you know it will work in the next outage.

What it costs

The emergency service call is $299, applied toward the repair when you approve it. Transfer switch repairs and generator work are quoted in writing first. Planning a new system? See generator installation.

FAQ

Generator Won't Start or Transfer: FAQ

Why won't my standby generator start during an outage?

The most common causes are a weak battery, an active alarm, the controller not in AUTO, or a fuel supply problem. Check the controller display first; if you can't clear it, call for service.

My generator is running but the house has no power. Why?

Usually the transfer switch didn't transfer, or the generator's breaker tripped. Shut the generator down and have the transfer switch checked by a licensed electrician.

Can I plug my portable generator into a dryer outlet?

No. That's backfeeding, and it can electrocute utility workers and damage your home. Use a generator interlock or transfer switch.

Do you service all generator brands?

We repair the electrical side — transfer switches, wiring and connections — for all brands, and coordinate with authorized dealers for engine warranty work.
