Electric Blankets and Heated Mattress Pads: A Safety Check Before the First Cold Night

Mid-October is when the electric blanket comes out of the linen closet in a lot of homes around Mequon. It's a cozy way to warm up the bed, and some people like being able to turn the thermostat down a bit at night.

Electric bedding is much safer than it used to be. UL Solutions, the product-safety testing company, notes that electric bedding sold in the U.S. since the late 1980s puts out much less heat than older models, and that newer blankets come with built-in safety features like better temperature controls and automatic shutoff. Still, a blanket that has spent months folded in a closet deserves a quick look before you plug it in. So does the outlet it's going into.

Look the blanket over first

Before the first use of the season, spread the blanket or pad out flat in good light and check:

Both sides of the fabric for dark, charred, or scorched spots.
The cord, plug, and connectors for cracks, breaks, or loose fittings.
The controller for cracks or a loose connection where the cord joins the blanket.

UL Solutions' advice is simple: if the blanket shows signs of damage, throw it out. Don't try to tape a cord or patch a scorched spot.

It's also worth a quick search on the U.S. Consumer Product Safety Commission's recalls page. Electric blankets have been recalled over the years for overheating, and it takes a minute to check your brand and model.

Use it the way it was designed

Most problems with electric blankets come from how they're used, not from the blanket itself. UL Solutions recommends:

Never fold or bunch it while it's on. Folds can damage the wires inside and trap heat.
Don't pile bedding or anything else on top of an electric blanket while it's heating.
Don't combine it with a heating pad. Layers of heat can get trapped in the bedding and cause burns.
Skip sofa beds, pullouts, and adjustable beds, where the moving parts can pinch the wires.
Warm the bed, then turn it off before you go to sleep. Turn it off and unplug it when you're done.
Keep pets away from it. Chewed wires are a shock and fire risk.
Store it rolled, not folded.

Watch where the cord goes

This is where a blanket problem turns into an electrical problem. UL Solutions warns against running cords under rugs, stapling or pinning them to walls, or routing them between the mattress and box spring. Watch for spots where the bed frame, slats, or footboard can pinch the cord, too. A pinched cord can wear through its insulation without anyone noticing.

Plug it into a healthy outlet

The bedside outlet often gets ignored for years. It might be hidden behind a nightstand with a lamp, a phone charger, and a clock all plugged in. Before you add a blanket, take a look:

Does the plug fit snugly? A plug that wiggles or falls out of the outlet points to worn contacts inside it.
Is the faceplate warm, discolored, or cracked? None of those are normal.
Is it an old two-prong outlet? Many older homes still have them in bedrooms. Our guide to replacing two-prong outlets before heating season explains your options.
Is the circuit already busy? If a space heater runs in the same room, see our space heater circuit safety guide before stacking more heat on one circuit.

Bedroom circuits in many homes are protected by AFCI breakers, which are designed to trip when they sense dangerous arcing in the wiring or cords. Heating season is a good time to test them. Our post on testing AFCI breakers monthly walks you through it.

Signs to stop and call an electrician

Unplug the blanket and leave that outlet alone if you notice:

A burning or hot-plastic smell near the bed, the outlet, or the cord.
Buzzing, crackling, or sparks when you plug something in.
A warm or scorched outlet or switch plate.
A breaker that trips when the blanket or another heater comes on, especially if it happens more than once. Our guide to a circuit breaker that keeps tripping explains why resetting it over and over is a bad idea.
Lights that dim or flicker in the bedroom when the blanket or a heater kicks on.

A worn blanket is easy to replace. A loose or overheating connection inside the wall needs a professional. Our electrical troubleshooting team can track down the cause. If you live in an older home and want the whole picture, a home electrical inspection covers the panel, circuits, and outlets before winter sets in.

A five-minute check worth doing

Spread the blanket out, check the cord, look up recalls, and give the bedside outlet a once-over. It's an easy habit for the first cold week of the year in Ozaukee County.
