Protecting Your Fridge and Freezer, at a Glance
When the power goes out, the fridge and freezer are usually the first worry in the house — and keeping them safe is easier than you'd think once you know the rules. This guide covers the food-safety timing, how a generator keeps things cold, and practical tips for town and rural homes alike. There's a printable 29-page version up top.
Common Questions
1 How long does food stay safe in the fridge and freezer without power?
A closed refrigerator keeps food safe for about 4 hours. A full freezer holds safe temperatures for about 48 hours if the door stays shut, or about 24 hours if it's only half full.
2 How do I know if food is actually safe to eat?
Use an appliance or freezer thermometer rather than guessing. Any perishable food held above 40 degrees for more than 4 hours should be thrown out — when in doubt, throw it out, and never taste food to test it.
3 Do I need to run the generator constantly?
No. Because the fridge and freezer both hold their cold for a while once chilled, many households cycle the generator — running it for a few hours at a time rather than nonstop — which saves fuel and keeps things quieter.
4 What size generator do I need just for the kitchen?
Often smaller than people expect. The fridge and freezer are a modest, steady load with one starting surge to plan for — our sizing guide walks through reading the nameplate and adding it up.
5 Should I power the fridge with cords or a full panel hookup?
Most homes power a fridge and freezer with a simple outdoor-rated extension cord straight from the generator. If you're already installing a transfer switch or interlock for other circuits, the kitchen is usually folded into that same plan.
6 What should I do with a chest freezer full of food?
Keep it as full and undisturbed as possible — a packed chest freezer holds cold especially well because cold air sinks and the lid opens from the top. Prioritize it in your generator's cycling schedule if it's holding a season's worth of food.
Would You Rather I Just Help?
Food-safety worries during an outage are one of the calls I get most — and getting your kitchen set up right, ahead of time, takes the worry out of it. I'll help you figure out the safe hookup and a cycling schedule that fits your generator, with nothing to sell you. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
