General Gas Cooktop Repair Guides

Do not guess what a gas-cooktop code means across brands. Photograph or write the complete code, model number, fuel type, affected burner, and when the message appeared.

A gas cooktop can click briefly while electronic ignition lights a selected burner, and some models can click again when a draft or spill extinguishes a flame and reignition starts. A popping noise can follow a wet burner or a cap that is not seated correctly.

A gas cooktop that is not heating usually has no usable flame, a weak or uneven flame, a blocked or wet burner, a mis-seated cap, a control/ignition issue, or an interrupted gas supply. First turn the control off and check for gas odor, hissing, smoke, burning smell, abnormal flame, or a burner that will not shut off.

If a gas cooktop will not ignite, turn the affected knob fully off first and identify whether you hear clicking, see a spark, smell unburned gas, or have no gas at any burner. A brief click and spark while a knob is in the ignition position can be normal, but a burner that does not light must not be left allowing gas to flow.

First determine whether the whole gas cooktop is inactive, one burner fails, there is gas but no spark, or there is a spark but no flame. A control lock, loss of supply, wet or misaligned burner parts, blocked ports, or an ignition fault can produce similar symptoms.

Treat a gas smell from a cooktop as a possible leak or unsafe combustion event: turn controls off only if you can do so without delay or entering danger, leave the building, and do not operate switches, phones, ignition controls, or other electrical equipment in the suspected leak area. Get gas-utility or emergency help from a safe location and do not return to troubleshoot until qualified help says it is safe.

A gas cooktop normally clicks and sparks while a knob is pushed in and turned to Ignite, and some sealed-burner designs make all burners spark when one burner is selected. Sparking should stop after a stable flame appears and all knobs are returned fully to OFF.

Do not keep resetting a breaker that trips with a gas cooktop. First record whether it trips as soon as the cooktop is connected, only when a burner is turned to Ignite, or after a spill or cleaning.
