RANGE REPAIR OR REPLACE GUIDE
Repair or Replace Your Electric Range? A Thornhill Homeowner’s Guide
If your electric range’s hot-surface light won’t turn off, or one or two burners have stopped heating, you’re likely facing a worn-out switch or wiring issue, not a reason to buy a new range. We have been diagnosing and repairing electric ranges for over 10 years, and this exact combination of symptoms comes up on service calls all the time.
We help homeowners throughout Thornhill, Vaughan, North York, Markham, Richmond Hill, Maple, Toronto, and the surrounding GTA every day. Below, we’ll walk you through what’s likely causing the problem, when repair makes sense, and when it’s time to replace the whole range.
Should I Repair or Replace My Electric Range?
In most cases, repair it. When one or two burners stop heating, or the glass top is otherwise undamaged, the cause is usually a worn infinite switch or a loose wiring connector, both of which cost far less to fix than a new range. Repair is the clear choice when the range is under 10 years old and the glass top is intact.
Replacement starts to make more sense once the range is older, the glass top is cracked, or the repair cost creeps close to what a new range would cost. That said, on higher-end ranges, repairing a cracked cooktop can still be the better deal, since replacing the whole range costs far more than replacing the top.
Does This Sound Like Your Range?
This problem usually shows up in a specific pattern. Most customers who call ARNI Services describe the following situation.
One or two burners no longer heat up, no matter how high the dial is turned.
The hot-surface indicator light stays on well after the cooktop has cooled down.
The burners that stopped working are the ones used most often.
The oven and the remaining burners still work normally.
The glass cooktop itself has no cracks, chips, or visible damage.
The problem came on gradually over weeks or months, not all at once.
When burners fail one at a time while the rest of the range works fine, that pattern is your most important clue. It points to the individual infinite switch or wiring behind each affected burner, not a problem with the range as a whole. That’s also why replacing the entire cooktop is rarely necessary here, unlike a cracked glass top, which usually calls for full replacement.
The Most Likely Cause: Worn Infinite Switch
On glass-top electric ranges, each burner has its own infinite switch that controls how much power reaches the heating element. When one switch fails, it cuts power to only that burner, while the other burners and the oven keep working normally, because each burner runs on its own separate switch and circuit.
That is why one or two burners can go dark while the rest of the range works fine. Different switch, different circuit.
This is a known failure point on ranges that have been in daily use for 8 years or more, especially on the burners used most often. It is also one of the most recognizable patterns our ARNI Services technicians see on electric ranges across Thornhill, Vaughan, and Toronto.
Check for Loose Wiring Before Replacing the Switch
Why This Check Matters
A new infinite switch carries a real cost, so before ordering one there is an important check to do first. Our technicians always inspect the wiring behind the affected burner before recommending a switch replacement, because a loose or damaged connection can cause the exact same symptoms for a fraction of the price to fix.
Electric ranges route wiring behind the cooktop to each burner’s switch and element. Heat cycling from daily cooking can loosen these connections or discolour the wiring over time, even when the switch itself is still good.
What You Can Safely Check Yourself
- Confirm which burner or burners have stopped heating.
- Check whether the hot-surface indicator light is also staying on.
- Look at the glass cooktop for cracks, chips, or scorch marks.
- Turn the affected burner’s dial and listen for a faint click, which is the switch engaging.
- Note whether the problem came on suddenly or built up gradually.
Because the wiring and switches on an electric range carry higher voltage than most household repairs, checking behind the cooktop is best left to a licensed technician. This keeps you safe and avoids voiding your appliance’s warranty.
Why This Happens on Older Electric Ranges
A range that has cooked dinner every night for 8 or more years has done its job well. But at that age, two specific failure points become common.
Infinite Switches Wear Out
The internal contacts inside an infinite switch cycle on and off constantly to regulate heat. After years of daily use, these contacts wear down and eventually stop making a clean connection, cutting power to the burner entirely.
Wiring Connectors Loosen With Heat
The wiring behind the cooktop expands and contracts with every cooking session. Over years of heat cycling, connectors can loosen or wires can discolour, especially near the burners used most often.
Neither of these is a manufacturing defect. It is simply the reality of long-term wear on a hardworking appliance.
Repair or Replace: What Makes Sense for an 8+ Year Old Electric Range?
Repair Usually Makes Sense If…
- The glass cooktop has no cracks or chips.
- Only one or two burners are affected.
- The oven and remaining burners work normally.
- The range hasn’t needed several repairs recently.
A switch replacement or wiring repair will usually cost much less than buying a new range.
Replacement May Make Sense If…
- The glass cooktop is cracked or badly scratched.
- The range is past the 10-year mark.
- You’ve had more than one repair in the past two years.
- Several components are starting to fail at once.
In that case, replacement deserves a closer look before spending more on repairs.

People Also Ask
What causes an electric range burner to stop heating suddenly?
The most common cause of a burner that suddenly stops heating is a worn infinite switch, especially when the oven and other burners still work normally. A loose or damaged wiring connector behind the cooktop is the second most common cause and is worth checking first since it is usually the less expensive repair.
Why does my hot-surface light stay on after the burner cools down?
The hot-surface indicator light runs on its own sensor circuit, separate from the burner itself. When it stays on after the cooktop has cooled, it usually points to a wiring or sensor fault on that circuit. It is not a safety hazard on its own, but it can be an early sign that other components on the same control board are starting to wear out.
Why did two burners on my range stop working at the same time?
When two burners fail around the same time, a shared wiring harness or connector behind the cooktop is often the cause. If the burners are not adjacent, it may simply be that both infinite switches wore out around the same age, since they typically see similar use over the life of the range.
Can loose wiring cause an electric range burner to stop heating?
Yes. Electric ranges route wiring behind the cooktop to each burner’s switch and element. Heat cycling from daily cooking can loosen these connections over time, even when the switch itself is still good. Checking the wiring before replacing the switch can often save money.
Is it safe to keep cooking on my range if one burner isn’t working?
Yes. Each burner runs on its own switch and circuit, so a single failed burner does not affect the safety of the oven or the other burners. It is still worth having the range inspected soon, since worn switches and wiring should be checked by a licensed technician given the higher voltage involved.
Is it worth repairing an electric range that is over 10 years old?
In many cases, yes. If the glass cooktop has no cracks and the rest of the range is working normally, repairing an infinite switch or a wiring connector is usually much less expensive than buying a new range. At ARNI Services we provide an honest assessment before recommending any repair.
How much does it cost to fix an electric range burner in Thornhill or Vaughan?
The repair cost depends on the actual cause of the problem. A wiring repair is typically less expensive than replacing a switch, and both cost far less than replacing the glass cooktop assembly. At ARNI Services we diagnose the fault first and provide a clear quote before any repair begins, with no hidden fees.
