Same-Day Cooktop Repair in Denver Metro area

Some clicking is normal. On most gas cooktops all igniters spark together when any knob is turned to LITE, and only the burner you selected should light. Samsung and JennAir both describe this, and JennAir adds that cooktops with a reignition feature spark again on their own if a draft or a spill puts the flame out.

Clicking that does not stop after the knob is off LITE is most often moisture. Samsung traces it to water on the ignition switches behind the knobs, and JennAir to burners that are still damp after cleaning or a boilover. Let the cooktop dry completely, for several hours or overnight. If it keeps clicking after that, a switch or the spark module needs to be tested, and that is a repair visit.

A burner that will not light at all usually has a cap or port problem first. Use the checks below. Flame color tells you the rest: Whirlpool describes a proper natural gas flame as soft blue. A flame that is yellow, noisy or lifting off the burner can be clogged ports or a cap that is not seated, but GE and Whirlpool also link yellow flames and soot to gas pressure, an incorrect LP conversion or orifices that need to be changed. Those are not owner fixes.

If you smell gas or suspect a leak, do not try to find it and do not call an appliance repair company first. Xcel Energy, the Denver area gas utility, tells customers to leave immediately and call 911 once safely outside, and then to contact Xcel Energy at 800-895-2999. Once the utility or emergency responders say the home is safe, we can diagnose the cooktop itself.

• Turn the knob fully to LITE and confirm the cooktop has power: an electric igniter does not spark if the plug is out or the breaker is off.
• Seat the cap: it should sit flush on its base with minimal side to side movement, and on cooktops with matching marks, the right cap goes on the right base.
• Clean clogged ports with a straight pin, needle or small-gauge wire once the burner is cool. JennAir warns against wooden toothpicks, which can break off inside the port.
• Dry the burner if it was just cleaned or something boiled over.

On a smooth glass radiant cooktop, an element that turns on and off while you cook is usually doing its job. Frigidaire explains that radiant elements are designed to cycle even on High, to hold steady heat and protect the glass from overheating, and that cycling looks more frequent with a pan that is smaller than the element or has an uneven bottom. GE adds that a pan that is not flat makes the built-in heat sensors cut the element off early.

When an element does not heat at all, start with the power. Whirlpool lists the control lock, the breaker and a power reset: turn the breaker off for one minute and back on. Electric ranges need a 240V circuit, and Whirlpool says to call an electrician if the breaker keeps tripping.

Coil cooktops have one more test. GE notes that plug-in coil elements can work loose in their sockets, and suggests moving a dead element to a working receptacle of the same size. If it still does not heat there, the element needs replacing. If it heats in the other socket, the fault is in the original receptacle, the infinite switch that controls that element or the wiring between them, and that is what the technician tests.

When an induction zone flashes or will not heat, the cookware is the first suspect. GE says pans that are not magnetic or are too small will not let an induction burner turn on, and that the pan must be flat, in full contact with the glass and centered in the marked circle. Whirlpool’s magnet test settles it: if a magnet sticks firmly to the bottom of the pan, it is induction compatible. Aluminum and copper usually do not work unless they have a magnetic base.

Power matters too. GE lists low supply voltage, for example a home with a 208 volt supply, and a tripped breaker or blown fuse as reasons an induction burner does not work. Bosch notes that most of its induction cooktops reset themselves after overheating once they have cooled completely.

A fan that keeps running after you turn the cooktop off is normal: GE and Whirlpool both say it protects the electronics and stops once the temperature drops. If a magnetic pan of the right size still is not detected, if one zone has died, or if the cooktop shows an error code that comes back after it cools, the problem is in the electronics. Check the code in your own manual first, then book a diagnosis.
