While the power is still out
The best thing for both the food and the freezer is a closed door or lid. By FDA's estimate, a packed freezer left closed keeps food frozen for about 48 hours, and one that is half full for about 24. GE's manuals are more cautious and tell owners to expect about 24 hours with warm air kept out.
Ready.gov advises disconnecting appliances during an outage so they are not damaged by a surge when power returns. For a freezer whose plug you can reach easily, unplugging it and plugging it back in once the power is steady is a sensible habit. Leave a lamp plugged in somewhere so you know when the power is back.
- Note the time the power went off; it matters later for the food.
- Put an appliance thermometer inside if there is not one already, opening it only once.
- Stack extra bags of ice or frozen water bottles around the food only if the outage is expected to run long.
- Keep children and helpers from opening it to check.

When the power comes back
Plug the freezer back in if you disconnected it, then give it several minutes. Many compressors will not start the instant power returns: GE lists a slow start after the freezer has been off as normal and credits built-in overload protection. Pressing buttons or unplugging it again during that wait only restarts the delay.
If nothing happens after ten minutes, check the power path. Storms and surges are exactly what trip breakers and outlets with test and reset buttons, and a garage or basement freezer is often on one of those while the kitchen is not. Reset the breaker or outlet once. A freezer that stays dead with power confirmed at the outlet needs a technician.
Once it is running, listen and look for the signs of a normal restart. Any one of them missing after half an hour is worth noting before you call.
- A steady hum from the lower back within a few minutes: the compressor has restarted.
- On a frost-free model, a fan audible behind the inside back panel once the door is closed.
- A power-on light or a display that stays lit rather than flickering.
- The thermometer falling, not rising, when you look again a few hours later.

What each kind of control does after an outage
The control decides what you see and what, if anything, you have to press. Most freezers fall into one of three groups.
A chest freezer with a dial
A mechanical dial remembers its position, so there is nothing to reset. The power-on light, where there is one, should glow as soon as power returns, and the compressor should start after its delay. Check that nobody turned the dial toward Off while trying to help during the outage.
An upright with an electronic panel
GE's electronic uprights sound a high-temperature alarm and flash the display after an outage has warmed the cabinet. Pressing Alarm Reset silences the sound and stops the flashing, but the High Temp light stays on until the freezer is cold again. If the cabinet cools before you press it, the alarm stops by itself and the display keeps flashing as a reminder that the power failed.
Built-in columns and undercounter drawers
These usually have the most detailed panels, and their manuals describe their own outage alarms and indicators. Photograph the panel before pressing anything, because some show how warm the cabinet got. Then silence the alarm as the manual describes and confirm the set temperature has not changed.
Helping it recover without overworking it
Four hours is the recovery time GE gives for an upright that has been off. Leave the setting where it was; turning it colder does not speed the pull-down. A fast-freeze function, such as GE's Turbo Freeze, which runs for 8 hours and then turns itself off, is useful if many packages have softened.
Keep the door shut during those hours and do not add groceries yet. Even a healthy upright is meant to take only a few pounds of fresh food per cubic foot in one go, and a freezer climbing back from a warm cabinet has even less spare capacity. Check the thermometer after 4 hours and again the next morning.

The food, in brief
FDA's rule after an outage is simple to state: food that still contains ice crystals or reads 40°F or below is safe to refreeze or cook. Perishable food that has been above 40°F for two hours or more should be thrown away. The food safety guide covers the details item by item, including how texture changes when food is refrozen.
