A failed automatic transfer switch in Florida stops the standby generator from powering the home — it's the licensed-electrical part that brings the generator online, a qualified-electrician job.
Handle it soon — these get more expensive with time.
Common causes:
• A worn or failed switch mechanism or relay
• A control board or sensing fault
• Wiring or connection degradation
• Age and cycling over years
• DIY replacement of a transfer switch
• A generator left unable to power the home
• Ignoring the back-feed safety role of the switch
• A permanent standby generator and its transfer switch are licensed electrician work — verify the electrical license and permit; a portable generator or panel shutter you handle yourself is different
What happens when a transfer switch fails?
The generator can no longer take over — it may run, but the home stays dark because the switch can't connect it to your panel and disconnect the utility. Since that connection also prevents dangerous back-feed onto the power lines, a failed switch is both a functional and a safety issue, and it's licensed electrical work to replace.
Is replacing a transfer switch expensive?
It's a meaningful part plus licensed electrician labor — less than a whole generator but not trivial, since it's line-voltage work done to code. Because it's the piece that makes the whole standby system function, a failed switch is worth replacing promptly with a qualified electrician rather than leaving the generator unable to help.
Automatic transfer switch: $500–$2,500 (typical ~$1,200)

This trade spans different license realities in Florida. A permanent standby generator and its transfer switch are licensed electrician work, and a gas connection needs a licensed gas or plumbing pro. Hurricane shutters and panels are often permitted specialty work tied to product approval and local wind-zone rules. Verify who holds the license for the part you are buying — a portable generator you plug in is different from a wired standby system.
Different scopes here carry different permit and license needs — ask who holds which before work starts.
