The storm passes, your power comes back on, and everything seems normal. Then your refrigerator starts making an unfamiliar noise. Your oven displays an error code. The ice maker stops working. Or an appliance that worked perfectly before the storm suddenly won’t turn on.
These can all be signs of appliance surge damage.
For Palm Beach County homeowners, thunderstorms, hurricanes, lightning, power outages, and fluctuations in the electrical grid are a reality of living in South Florida. While a major surge can cause an appliance to fail immediately, electrical damage isn’t always that obvious.
Knowing what to look for after a Florida storm can help you catch appliance problems before they turn into larger—and potentially more expensive—repairs.
What Is Appliance Surge Damage?
A power surge is a brief spike in electrical voltage. The Electrical Safety Foundation International (ESFI) explains that these voltage spikes can damage, degrade, or destroy electrical equipment.
Surges aren’t caused only by direct lightning strikes. They can also occur because of damaged power lines, electrical-grid switching, faulty wiring, large electrical loads switching on and off, and even when power is restored following an outage.
Learn more about power surges and surge protection from ESFI.
Today’s luxury appliances are particularly sophisticated. Refrigerators, ranges, ovens, dishwashers, wine coolers, and built-in coffee systems can contain electronic control boards, sensors, displays, and other components that depend on a consistent electrical supply.
That means appliance surge damage may affect the electronics inside an appliance even when there are no obvious signs of physical damage.
1. The Appliance Won’t Turn Back On
The most obvious warning sign is an appliance that worked before the storm but won’t power on afterward.
Before assuming the appliance has failed, check whether:
- The home has fully regained power
- The circuit breaker has tripped
- The appliance is receiving power
- A GFCI outlet has tripped, if applicable
If power is reaching the appliance but it remains unresponsive, an internal electrical component may have been damaged.
Avoid repeatedly resetting a breaker that continues to trip. Recurring electrical problems should be evaluated by a qualified professional.
2. You’re Suddenly Seeing Error Codes
An appliance doesn’t necessarily have to stop working completely after a surge.
You may instead see a new or unfamiliar error code.
This is particularly relevant for high-end appliances from brands such as Sub-Zero, Wolf, Miele, Thermador, Viking, and Monogram because these appliances rely heavily on electronic controls and sensors.
An error appearing immediately after an outage or storm is worth investigating—especially if you’ve never seen it before.
3. Your Refrigerator Isn’t Maintaining Temperature
Refrigerators and freezers deserve immediate attention after an extended outage or suspected electrical event.
Signs of a problem include:
- Refrigerator feels warmer than usual
- Freezer isn’t maintaining 0°F
- Compressor runs continuously
- Refrigerator repeatedly cycles on and off
- Displayed temperature doesn’t match the interior temperature
- New error messages appear
A refrigerator may still have lights and a functioning display while experiencing a problem with another component.
If you suspect appliance surge damage, don’t assume that a refrigerator with power is necessarily cooling correctly.
4. The Appliance Is Behaving Erratically
Electrical damage can sometimes cause strange behavior rather than complete failure.
Watch for appliances that:
- Turn themselves on or off
- Restart unexpectedly
- Have flashing displays
- Lose programmed settings
- Respond slowly to controls
- Cycle more frequently than normal
- Produce inconsistent temperatures
ESFI identifies unexpected equipment restarts or misoperation among the potential symptoms associated with power surges.
If an appliance begins behaving differently immediately after a storm or outage, have the problem diagnosed rather than waiting for it to fail completely.
5. You Hear New or Unusual Noises
You know how the appliances in your home normally sound.
After a storm, pay attention to new:
- Clicking
- Buzzing
- Humming
- Repeated cycling
- Unusual compressor noises
Not every unusual sound indicates appliance surge damage, but a sudden change following an electrical event deserves attention.
This is especially important for built-in refrigerators, wine refrigeration systems, and other appliances that may continue attempting to operate despite a component malfunction.
6. Your Oven or Range Isn’t Heating Correctly
Electronic controls play an important role in modern luxury cooking appliances.
Following a storm or outage, you might discover that your Wolf, Thermador, Viking, or other premium oven:
- Won’t heat
- Takes significantly longer to preheat
- Displays an error code
- Shuts down unexpectedly
- Doesn’t maintain the selected temperature
- Has an unresponsive control panel
Because cooking appliances combine high-voltage electrical components with heating elements or gas systems, avoid attempting internal electrical repairs yourself.
7. Your Ice Maker or Built-In Coffee System Stops Working
Sometimes the first sign of appliance surge damage appears in one particular function rather than the entire appliance.
Your refrigerator may continue cooling while its ice maker stops producing ice. A built-in Miele coffee system might power on but stop brewing correctly.
Luxury appliances frequently contain multiple electronic components and control systems, which means one function can fail while the rest of the appliance appears normal.
What Should You Do After a Power Outage?
Once conditions are safe and power has been restored, don’t immediately assume every appliance is operating normally.
Walk through your home and check your major appliances individually.
Pay particular attention to:
- Refrigerators and freezers
- Wine refrigerators
- Ice makers
- Ovens and ranges
- Dishwashers
- Washers and dryers
- Built-in coffee systems
- Outdoor kitchen appliances
FEMA’s Ready.gov recommends unplugging appliances and electronics during an outage when appropriate to help protect them from electrical surges. You can review FEMA’s power outage safety recommendations for additional guidance.
If your home experienced flooding or water reached electrical equipment, that’s a different situation. Do not simply turn the equipment back on. ESFI recommends that appliances or equipment affected by floodwater be checked by a qualified professional before being energized.
Can a Surge Damage an Appliance Without Destroying It?
Yes—and this is one reason post-storm problems can be confusing.
A voltage surge can degrade electrical components without causing immediate total failure. ESFI notes that repeated smaller surges can gradually damage electronics and shorten equipment life.
That means an appliance could continue operating but begin experiencing intermittent problems after an electrical event.
If you notice a clear change in performance after a storm, don’t ignore it simply because the appliance still turns on.
Can You Protect Luxury Appliances From Power Surges?
Surge protection can reduce risk, although no system can guarantee protection from every electrical event.
Importantly, a standard power strip isn’t necessarily a surge protector.
ESFI recommends surge protective devices (SPDs) and explains that whole-home protection can help protect hardwired equipment and large appliances that can’t simply be plugged into a conventional point-of-use surge protector.
A qualified electrician can evaluate whether your home’s existing electrical system has appropriate surge protection.
For Palm Beach County homeowners with tens of thousands of dollars invested in Sub-Zero refrigeration, Wolf cooking appliances, wine storage, built-in coffee systems, and other luxury equipment, whole-home electrical protection may be worth discussing with an electrician.
When to Schedule Appliance Repair After a Storm
Consider scheduling professional service if an appliance:
- Stopped working following a storm or outage
- Is displaying a new error code
- Won’t maintain the correct temperature
- Makes new or unusual noises
- Cycles on and off unexpectedly
- Has an unresponsive control panel
- Isn’t performing the way it did before the storm
The sooner appliance surge damage is identified, the sooner you can determine whether an individual component can be repaired or replaced.
