Cooktop Not Working? Here's Why (And How We Fix It in Edmonton)
Whether you have a gas, induction, or electric cooktop, a burner that won't heat is frustrating — especially at dinner time. Here are the most common causes our Edmonton technicians find, and what you can check before calling for service.
Gas Burner Won't Light
A gas burner that clicks but won't ignite is one of the most common cooktop calls we receive in Edmonton. The igniter — the small ceramic electrode beside each burner — can become coated with food debris, grease, or moisture, preventing it from producing a strong enough spark to light the gas.
Start by removing the burner cap and cleaning around the igniter port with a dry toothbrush. If the burner still won't light after cleaning, the igniter itself may be cracked or the igniter module may have failed. A certified technician can test the igniter's resistance and replace it if needed — a repair that typically takes under an hour.
Never attempt to light a gas burner manually if you smell gas. Turn off the cooktop, ventilate the kitchen, and call a technician before using the appliance again.
Induction Cooktop Not Heating
Induction cooktops heat by generating a magnetic field that excites the iron molecules in compatible cookware. If your induction cooktop powers on but won't heat, the first thing to check is your cookware — induction only works with ferromagnetic pots and pans. Hold a magnet to the bottom of your pot: if it sticks firmly, the cookware is compatible.
If the cookware is compatible but the zone still won't heat, the most likely culprits are a failed induction coil, a blown thermal fuse, or a faulty control board. Induction coils operate at high temperatures and can burn out over time, especially if the cooktop has been used with oversized cookware that blocks airflow to the cooling fan.
Induction repairs require disassembly of the glass surface and high-voltage components — this is not a DIY repair. Our Edmonton technicians carry common induction coil assemblies and control boards for major brands including Samsung, LG, Bosch, and KitchenAid.
Electric Coil Element Not Working
On a traditional electric coil cooktop, a burner that won't heat at all usually has a burned-out coil element. You can often confirm this visually — a failed element may show a break or blister in the coil. Coil elements are one of the most affordable cooktop repairs, and most can be swapped out in minutes without tools.
If the element looks intact but still won't heat, the problem may be the drip bowl receptacle block — the socket the coil plugs into. Receptacle blocks corrode over time and lose their connection. A technician can test the block with a multimeter and replace it if needed.
If multiple burners are dead at the same time, the issue is more likely an infinite switch (the dial that controls heat level) or a wiring fault rather than multiple failed elements.
Glass Ceramic Cooktop Cracked or Not Responding
A cracked glass ceramic cooktop is a safety hazard — sharp edges and the risk of electrical exposure mean you should stop using the appliance immediately. Glass ceramic surfaces can crack from thermal shock (placing a cold pot on a hot surface), impact, or manufacturing defects.
Glass ceramic replacement is one of the more involved cooktop repairs, as the entire surface must be removed and the heating elements underneath carefully disconnected. Depending on the brand and model, a glass replacement can be cost-effective compared to a new cooktop — our technicians will give you an honest assessment before proceeding.
If the glass is intact but the touch controls are unresponsive, the control panel ribbon cable or the main PCB may have failed. A hard reset (unplugging the cooktop for 60 seconds) sometimes resolves a locked-up control panel — if not, a technician can diagnose the electronics.
Cooktop Keeps Clicking After Burner Is Lit
Persistent clicking after a gas burner is already lit is almost always caused by moisture inside the igniter assembly. This happens after a boil-over or after cleaning the cooktop with too much water. Remove the burner cap and grate, and allow the area to dry completely — sometimes overnight — before trying again.
If the clicking continues after the cooktop is fully dry, the igniter switch may be stuck or the igniter module may be faulty. A stuck switch can sometimes be freed by pressing the burner knob in and out several times, but a faulty module will need to be replaced by a technician.
When to Call a Professional
Some cooktop issues — dirty igniters, a tripped breaker, incompatible cookware — are safe to investigate yourself. But any repair involving gas connections, high-voltage induction components, or a cracked glass surface should be handled by a certified technician.
