Hurricane Season Appliance Checklist for Jacksonville Homes

Jacksonville’s real hurricane risk is not the wind. It is the outage: a storm that never makes landfall here still takes down feeders across Duval, St. Johns and Clay counties, and restoration in a mature tree canopy takes days rather than hours. Add roughly 68 thunderstorm days a year on top of named storms and you have a region where every household with serious refrigeration should have a rehearsed plan.

This is that plan. It is deliberately boring, and it is in the order you actually do it.

Before: the week the cone appears

Freeze thermal mass. Fill containers and bottles with water and freeze them, and fill any empty space in the freezer. A full freezer holds safe temperature roughly twice as long as a half-empty one, because what protects the food is the frozen mass inside, not the cabinet. The same ice is drinking water later.

Turn everything down. Set both compartments to their coldest settings a day or two ahead. Pre-chilling the contents is free hours.

Make the coin test. Freeze a cup of water solid, set a coin on top of the ice, and leave it in the freezer. If you evacuate and come back to find the coin at the bottom of the cup, the freezer thawed completely and refroze at some point — which no amount of feeling the packages will tell you. If it is still on top, nothing thawed all the way through.

Consolidate. Move what you actually care about into the freezer, toward the back and low. Put raw meat on a tray on the bottom shelf so a thaw does not drip onto everything below it. Take a photo of the contents of both boxes: it is a two-second job that becomes an insurance claim document.

Check the seals. Close each door on a dollar bill and pull. If it slides out with no drag anywhere around the perimeter, the gasket is not sealing, and a bad gasket during an outage costs you hours you do not have.

Deal with the water. Empty the reservoirs on built-in coffee systems and steam ovens. Run the dishwasher and leave it empty. Empty the washer. Four days without air conditioning in a Florida August turns standing water in a sealed appliance into a mould problem you meet in week two.

Know your panel. Every breaker labelled, legibly, before the storm — not by flashlight during it.

Before: the last few hours

Once the refrigeration is as cold as it is going to get, open the breakers for the ovens, the cooktop, the dishwasher, the laundry, the wine storage, the ice machine and anything else with a control board. Leave the refrigerator and the freezer running on utility power until it actually fails, then open their breakers too.

This matters more than most people expect. The damage we see after storm weeks is rarely from a lightning strike. It is from restoration: power returning hard, or returning as sustained low voltage while the utility works a circuit back up. A brownout is harder on a motor and on an inverter drive than a clean outage is, and no surge protector addresses it. An open breaker does.

If you have a whole-home surge protective device at the panel, this is the moment to look at its status indicator. They are consumable, and one that has quietly failed protects nothing.

During: the two rules

Keep the doors shut. An unopened refrigerator holds safe temperature for about four hours. A full freezer holds for about 48 hours; a half-full freezer for about 24. Those numbers are the USDA’s, they assume the door stays closed, and every opening spends a real fraction of them. If you will be reaching for drinks and snacks repeatedly, load a cooler once and live out of it.

Generators go outside. Well away from windows, doors, vents and screened enclosures. Never in a garage, not even with the door up. Carbon monoxide is odourless and it kills people in Florida after every major storm. Feed the house through a transfer switch installed by an electrician — never back-feed through a dryer or range receptacle, which energises the utility line a lineman may be working on.

If a generator is running the refrigeration, put a thermometer in each compartment and read it. Undersized or unstable generator power runs a compressor without ever getting the box to temperature, which looks like success and is not.

Dry ice is the other option. USDA guidance puts roughly 50 pounds as enough to hold a full 18-cubic-foot freezer for about two days. Wear gloves, never seal it in an airtight container, and keep the space ventilated.

After: temperatures first, food second

Read a thermometer in each compartment before you make any decision about food. Do not judge by touch and do not, under any circumstances, taste anything — the organisms that cause foodborne illness do not change how food looks, smells or tastes.

The rules are simple and worth following exactly:

• Discard anything perishable that has been above 40°F for two hours or more: meat, poultry, seafood, eggs, milk and soft cheeses, cut fruit and vegetables, cooked leftovers, and anything containing them.
• Refreeze freezer items that still contain ice crystals or that read 40°F or below. Quality drops; safety does not.
• When in doubt, throw it out. A freezer’s worth of food is cheaper than an emergency room.

Hard cheeses, butter, unopened shelf-stable items, whole uncut fruit and most condiments survive fine. The judgement calls are all in the protein and dairy.

After: restarting in the right order

1. Wait. Give it several minutes after utility power returns to confirm it is stable rather than flickering.
2. Refrigeration first, one appliance at a time. Close its breaker, let it start, then move to the next. Do not close every breaker at once and let the whole kitchen inrush together.
3. Wine storage next. It has been drifting warm and it wants to come back slowly.
4. Everything else last — ovens, cooktop, dishwasher, laundry, ice machine.
5. Note the time. Write it down.
6. Assess at 24 hours, not at one. A built-in that has been off for days is warm all the way through, including its own mass. Refrigeration setpoints are typically 38°F for the fresh food compartment and 0°F for the freezer, and an ice maker will not resume production until the freezer is genuinely at or below 5°F. If the box is still not at setpoint 24 hours after a proper restart, that is the point at which it needs a technician.
7. Dump the first ice. Two or three batches, minimum. Ice that partially melted and refroze has absorbed everything else in that freezer, and if JEA issued a precautionary boil water notice, the supply line needs flushing before the ice is worth keeping. Consider changing the water filter afterwards as well.

What not to do

• Do not taste anything to test it.
• Do not put warm or partially thawed food back into a freezer that is still recovering — you are asking a struggling appliance to do the hardest job there is.
• Do not run a generator anywhere with a roof over it.
• Do not back-feed the house through an appliance outlet.
• Do not power up an appliance that has been in flood water. Cabinet insulation holds water indefinitely, motors ingest silt and salt, and boards corrode for months afterwards. Photograph it and call your insurer.
• Do not keep opening the doors “just to check”. The thermometer tells you what you need to know from outside.
• Do not assume a blank display means the appliance is dead. It frequently means a control board or a power supply, which is a part rather than a replacement.

Every August we get the same three calls: a built-in that will not wake up, a freezer full of food somebody is not sure about, and an ice maker that never restarted. The first is a repair, the second is a checklist, and the third is usually just a freezer that has not reached 5°F yet.
