Stove Burner Not Heating? 5 Checks for Electric Coil Burners

You turn the dial, wait a minute, and one burner on your electric stove stays cold while the others glow red. It's one of the most common stove problems in Toronto kitchens, and the good news is that a coil burner that won't heat usually has a simple cause. Here's how to narrow it down safely, what you can fix yourself, and when it's worth calling a pro.

Safety first

• Make sure every burner is off and completely cool before you touch anything.
• For anything beyond lifting out a coil, turn the stove off at the breaker panel or unplug it. Electric ranges run on 240 volts.
• Never touch the terminal block under the cooktop or the wiring behind the controls while the stove has power.

Step 1: Reseat the coil element

Coil elements plug into a receptacle (the little socket under the cooktop) with two metal prongs. Cleaning the stove, moving a heavy pot or simply lifting the drip pan can knock a coil slightly out of place, so it no longer makes contact.

• Lift the cold coil a few centimetres and pull it straight out of its socket.
• Push it back in firmly until it sits flat and level in the drip pan.
• Turn the burner on high and give it two minutes.

If it heats now, you're done. If it heats on and off when you wiggle it, the socket is likely worn (see Step 4).

Step 2: Swap it with a working burner

This is the single most useful test, and it costs nothing. Most stoves have two small and two large burners, so take the cold coil out and plug it into the matching size position that works.

• The coil heats in the other spot: the element is fine. The problem is the socket, the switch or the wiring on the original side.
• The coil stays cold in the other spot: the element itself has failed and needs replacing.

Step 3: Look the element over

With the coil out, check it under good light. Signs of a failed element include a blister or bubble on the coil, a crack or a split, a spot that looks burnt or melted, or prongs that are black, pitted or bent. Any of those mean it's time for a new element. Replacement coils are matched by size and prong style, so bring the old one or the model number when you buy.

Step 4: Check the receptacle (socket)

Look into the socket the coil plugs into. If it's scorched, cracked, or the metal contacts look burnt, it can stop delivering power even with a brand-new coil. A burnt receptacle often damages the new element too, so it's best to replace the two together. Because this means working with the stove's wiring, turn the power off at the breaker before you go any further, or leave it to a technician.

Step 5: Suspect the infinite switch

If a known-good coil and a clean socket still give you no heat, or the burner only works on high, the burner's control switch (often called an infinite switch) is the usual cause. These switches wear out over years of daily use. Testing one properly involves a multimeter and live 240-volt circuits, so this is where most homeowners should stop and call a pro.

When more than one burner stops working

If two burners on the same side, or every burner and the oven, quit at once, check your electrical panel first. A range uses a double breaker, and if one half trips you can lose part of the stove. Reset it once. If it trips again, don't keep resetting it. That points to a short that needs a technician.

When to call a pro

Call for service if the swap test points to the socket, switch or wiring, if you see burn marks under the cooktop, if a breaker keeps tripping, or if you simply don't want to work around 240-volt wiring. A technician can test the element, receptacle and switch on the spot and usually carries common parts. Our stove and oven repair service in Toronto covers electric coil, glass-top and induction ranges across Toronto, North York, Scarborough and Etobicoke.

The service call is $70 plus HST, and it's waived when you go ahead with the repair. Prices are the same evenings and weekends, and the same in all four areas we serve. You can see typical prices on our appliance repair cost page.

FAQ

Is it safe to keep using the other burners?

Usually yes, as long as there are no burn marks, sparks or a burning smell. If you notice any of those, stop using the stove and turn it off at the breaker until it's checked.

Why does my burner only work on high?

That's a classic sign of a worn infinite switch. The element and socket are fine, but the switch can no longer cycle power at lower settings.

Is a stove burner worth repairing?

In most cases yes. A new coil, socket or switch costs far less than a new range, and an electric stove that's otherwise in good shape can keep going for years.

Can I replace a coil element myself?

Yes. If the swap test shows the element is bad, a matching replacement just plugs in. Socket and switch repairs involve wiring and are better left to a technician.
