How to Prepare Your Appliances Before a Halifax Winter Storm

When Environment Canada issues a winter storm warning for Halifax, most people think about bread, milk, and batteries. But spending 10 minutes preparing your appliances before the storm hits can save you hundreds of dollars in repairs and prevent significant food waste. Here is what to do.

The Fridge and Freezer

Your fridge and freezer are the most vulnerable appliances during a power outage because they contain perishable food and need continuous power to function.

• Turn the fridge and freezer to their coldest settings — this gives you a head start if power goes out; the colder they are when the outage begins, the longer food stays safe
• Fill empty freezer space — freeze water bottles, bags of ice, or even wet towels; a full freezer holds cold for up to 48 hours, a half-full one only 24
• Move important items to the freezer — raw meat and dairy you will not eat in the next 4 hours are safer in the freezer during an outage
• Have a thermometer in both sections — when power returns, you can verify the fridge stayed below 4°C before trusting the food

The Washer and Dryer

• Run any laundry you need done before the storm — a wet load stuck in the washer during a 2-day outage will develop mould and odour
• If a load is in the washer when power goes out — add a cup of white vinegar to prevent mildew; run the cycle again when power returns
• Clean your dryer lint trap and vent — after the storm you will likely have a backlog of laundry; a clean vent means faster drying and lower fire risk

Protect Against Power Surges

• Unplug non-essential appliances before the storm — dishwasher, microwave, oven, washer, dryer, and any smart appliances
• Leave the fridge plugged in (with a surge protector if possible) so it restarts automatically
• When power returns, wait 5 to 10 minutes before plugging things back in — power can spike and dip as the grid stabilizes
• Consider a whole-home surge protector if you do not already have one — installed at the breaker panel for $200 to $500, it protects every appliance in the house

Water Lines and Pipes

If you lose heat during an extended outage, frozen pipes become a real risk — including the water line to your fridge’s ice maker and water dispenser.

• Know where your main water shut-off valve is — if pipes freeze, you need to shut water off quickly to prevent flooding when they thaw
• If your home drops below 0°C inside — turn off the water supply to the fridge and disconnect the line if accessible; a burst fridge water line can cause serious water damage
• Open cabinet doors under the kitchen sink — allows warm air to circulate around pipes connected to the dishwasher

Post-Storm Appliance Checklist

Once power is back and stable, run through this checklist before relying on any appliance:

1. Check the fridge temperature — if above 4°C and food has been warm for more than 2 hours, discard perishable items per Health Canada guidelines
2. Listen to the fridge — if the compressor is clicking but not running, the start relay may need replacing
3. Run the dishwasher empty on a hot cycle — flushes any stagnant water from the pump and lines
4. Check all appliances for error codes — try unplugging for 10 minutes to reset; persistent codes may need professional clearing
5. Run the washer on a clean cycle — hot water with a cup of vinegar clears any odour from water sitting in the drum
6. Test the oven and stove burners — confirm they are heating normally before you need to cook a full meal
