Range and oven symptoms
Each ranges and ovens page answers one consumer question, shows what observation separates the likely causes, and stops before unsafe or model-specific repair. Error codes stay in separate manufacturer records.

223 complete records in this directoryCan I use a glass cooktop with a crack?
No. A crack can admit liquid to energized components and can spread under heat. Turn all elements off, disconnect power safely and arrange exact-model replacement.
Open record Ranges & ovens · combustionGas burner flame is yellow or orange instead of blue
Brief orange tips can come from airborne dust or humidity, but persistent yellow, lazy or sooting flames can indicate dirty ports, wrong fuel conversion or unsafe combustion.
Open record Ranges & ovens · gas ignitionGas burner keeps clicking after the flame lights
Continued clicking usually means moisture, a dirty or misaligned cap, flame not reaching the sensor, or an ignition-switch fault.
Open record Ranges · gas ignitionGas surface-burner ignition behaves incorrectly or produces the wrong result
A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. This record isolates gas surface-burner ignition through wet/dirty cap and ports versus electrode, gas supply and switch.
Open record Ranges · gas ignitionGas surface-burner ignition fails only on one cycle, load or operating condition
An appliance problem limited to one cycle, load, zone or operating condition should be separated from a component that fails every time. This record isolates gas surface-burner ignition through wet/dirty cap and ports versus electrode, gas supply and switch.

A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. This record isolates gas surface-burner ignition through wet/dirty cap and ports versus electrode, gas supply and switch.
Open record Ranges · gas ignitionGas surface-burner ignition is unusually slow or delayed
A delay can come from capacity, weak signal, background work, protection or a service wait; measuring the exact stage prevents the wrong repair. This record isolates gas surface-burner ignition through wet/dirty cap and ports versus electrode, gas supply and switch.
Open record Ranges · gas ignitionGas surface-burner ignition keeps disconnecting or working intermittently
Intermittent behavior is diagnosed by the trigger—movement, heat, load, sleep, distance or time—not by repeating broad resets. This record isolates gas surface-burner ignition through wet/dirty cap and ports versus electrode, gas supply and switch.

Open record Ranges & ovens · lightingOven light bulb keeps burning out
Repeated bulb failure can result from the wrong heat rating, loose socket, vibration, grease contamination or voltage problems.
Open record Ranges & ovens · temperatureOven says it is preheated but the temperature is still low
Many ovens signal before the entire cavity and cookware reach equilibrium. Compare temperature only after the manual’s full preheat and several heat cycles.
Open record Ranges & ovens · smokeOven smokes even when it looks clean
Smoke can come from hidden grease, foil/liner contact, manufacturing residue, cleaner residue or a failing electrical component. The odor and timing determine whether continued use is safe.
Open record Ranges & ovens · self-cleanOven smokes heavily during self-clean
Some odor is expected, but heavy smoke means excess grease or food remained. Keep the door closed, turn the cycle off if safe and treat flame as an appliance fire.
