What to check on your appliances after a power outage

When the power comes back after a storm, every appliance restarts at once. Most come back fine. Some do not, and knowing what to look for saves food and money.

    Checking a refrigerator after a power outage
    Quick answer

    After a power outage, check that refrigerators and freezers restart and begin cooling, look for scrambled displays or error codes on electronic appliances, reset tripped breakers, and watch for appliances that stay dark. Restart and surge damage usually hits control boards, relays and fuses rather than motors.

    Why outages are hard on appliances

    Long outages are a real part of life here. When Hurricane Irma came through in 2017, about 284,000 JEA customers lost power at the peak and restoration took days. Shorter summer thunderstorm outages happen far more often.

    The outage itself rarely hurts an appliance. The trouble comes when power returns: voltage can spike or sag, and every compressor in the neighborhood tries to start at the same time. Control boards, start relays and fuses take the hit.

    First hour: refrigerators and freezers

    Listen for the compressor and fans starting within a few minutes. Check that the freezer feels colder within an hour. If you hear a click every few minutes with no hum, the start relay or overload is struggling, which is a common post-outage failure.

    Keep the doors closed until it is cold again. A full freezer kept shut holds food frozen for about two days, a half-full one about one, and a refrigerator about four hours. When in doubt about thawed food, throw it out.

    Electronic appliances that act strangely

    Washers, dryers, dishwashers and ovens with digital controls sometimes come back with scrambled displays, lost settings or error codes. Turn the appliance off at the breaker for a minute and back on. That clears many glitches.

    If the display stays dark, the appliance will not start or the same error returns, the control board or its power supply may be damaged. That is a repair for a technician.

    Breakers, outlets and GFCIs

    Before assuming the appliance failed, check the breaker panel and any GFCI outlets nearby, especially in kitchens, laundry rooms and garages. A tripped GFCI in the garage is the most common reason a garage freezer stays off after a storm.

    Electric ranges and dryers use double breakers; one half can trip while the other stays on, leaving the appliance partly working.

    Protecting appliances before the next storm

    Appliance-rated plug-in surge protectors help refrigerators, microwaves and washers. A whole-home surge protector installed at the panel by an electrician protects 240-volt appliances too. During a lightning storm, unplugging electronics and smaller appliances is sensible. Keep the refrigerator plugged in unless you are leaving.
