Berkeley and the East Bay get PG&E power outages for several reasons: routine maintenance, storms, equipment failure, and — increasingly — PSPS (Public Safety Power Shutoffs) during high-wind, high-fire-risk periods. An outage of any length puts your appliances and your refrigerator contents under stress. This guide covers what to do at each stage.
When the Power Goes Out — First 30 Minutes
The most important thing you can do in the first half hour of an outage is nothing. Keep your refrigerator and freezer doors closed. Every time you open them, cold air spills out and warm air enters. A refrigerator with a good seal can maintain food-safe temperatures for 4 hours with the door closed — but only if you are not repeatedly opening it to check.
Food safety timelines — memorise these
Refrigerator section: food stays safe for about 4 hours with door closed. Full freezer: about 48 hours. Half-full freezer: about 24 hours. If the outage looks like it will extend beyond these windows, move perishables to a cooler with ice.
What Power Outages Do to Your Refrigerator
Your refrigerator compressor is designed to cycle on and off throughout the day. A normal off-cycle lasts 15 to 20 minutes. A power outage lasting hours puts the sealed refrigeration system under three distinct stresses:
- Thermal stress from the restart: When power returns after a long outage, the compressor restarts into a warm system. The refrigerant has warmed and the pressure differential is different from normal operating conditions. This is harder on the compressor than a normal cycle restart.
- Surge damage on restoration: Power restoration from the grid often comes back with a momentary surge before settling at 120V. This surge can damage electronic control boards, particularly on newer appliances with complex control systems.
- Defrost disruption: Modern refrigerators run auto-defrost cycles on a timer. A long outage disrupts this schedule. After power returns, the defrost cycle may run at an unusual time, which is normal. If it seems to run constantly for more than 30 minutes, that is worth checking.
Protect appliances from surge damage
A surge protector rated for appliances (not just a standard power strip) can protect refrigerators, washers, dryers, and dishwashers from power-restoration surges. In California where PSPS events and storm outages are common, this is worth investing in for your major appliances.
What Happens to Your Washer and Dryer During an Outage
If a power outage hits mid-cycle, your washing machine will stop with clothes in the drum — possibly full of water. When power returns, most modern washers resume from where they left off. If yours doesn't, running a new spin/drain cycle will clear the water from the drum before the clothing mildews.
Front-load washers have a door lock that engages during the wash cycle. After an outage, the door may remain locked even though the machine has stopped. Wait about 3 minutes after power returns — most machines unlock automatically after a brief delay once power is restored.
Sub-Zero, Wolf, and Premium Appliances During Outages
Premium built-in appliances tend to have more complex electronic control systems, which makes them more susceptible to surge damage on power restoration. If you have a Sub-Zero refrigerator in your Berkeley home, consider plugging it into a dedicated appliance surge protector.
After a long outage, a Sub-Zero refrigerator may display an EC code once power returns. Many of these clear on their own once the unit re-stabilizes to set temperature over 2-4 hours. Our Sub-Zero EC code guide explains what each code means and which ones clear on their own versus which need a technician.
PSPS Events in Berkeley — What Makes Them Different
A standard storm outage typically lasts 2-8 hours. A PSPS event can last 12 to 72 hours or longer depending on how quickly PG&E clears the safety hazard. The extended duration is what makes PSPS outages genuinely problematic for food and appliance safety.
During a PSPS outage lasting more than 24 hours:
- Transfer all meat, fish, dairy, eggs, and prepared foods to a cooler with ice within the first 4 hours
- Leave condiments, hard cheeses, whole fruits, and packaged shelf-stable foods in the refrigerator
- Keep a thermometer inside the refrigerator and freezer to track temperatures if possible
- When in doubt about a specific food, discard it — food poisoning is not worth the cost of what you would have saved
When Power Comes Back — What to Check
- 1
Wait 15 minutes before evaluating anything
Refrigerators and freezers take time to restart the compressor and begin cooling. Give it 15 minutes before concluding anything is wrong.
- 2
Listen for the compressor running
You should hear the compressor start within a few minutes of power restoration. A click followed by silence, repeated every few minutes, means the compressor is trying to start but failing — usually a start relay issue. Call us at (510) 947-6664.

Check for error codes on the display
If your refrigerator, washer, or dishwasher shows an error code after an outage, check our error code guides. Many post-outage codes are temporary and clear on their own.
- 4
Run a test cycle on the washer and dishwasher
A short test cycle confirms these appliances are working correctly after the outage. Better to discover a fault on a test cycle than mid-laundry.
- 5
Call if anything seems wrong
Appliances that don't restart normally, show persistent error codes, or make unusual noises after a power restoration need a technician. Call (510) 947-6664 — we are open 24 hours and serve Berkeley and all East Bay cities same day.
Not all outage-related appliance failures are covered by PG&E
If your appliance was damaged by a power surge during an outage, PG&E may be liable depending on the cause of the surge. However, proving causation requires documentation. If you suspect surge damage to an appliance after an outage, call Fast Help for same day diagnosis — we can document the fault type and timing for any claim you might make.
Refrigerator Still Not Cooling After Power Returned?
If your refrigerator is running (you can hear it) but not cooling after an outage, check our detailed refrigerator not cooling guide which covers the five most common causes. If you've waited 2 hours after power restoration and the refrigerator is still not reaching normal temperature, call us — food safety is on the line and we dispatch same day across Berkeley, Oakland, and all 19 East Bay cities.
