A cooking range rarely fails without warning. Most system failures begin as minor irregularities. If you observe any of the following, your appliance requires immediate professional assessment to prevent component burnout or safety hazards.

1. Ignition Failure & uneven Flames

• The Symptom: The burner clicks continuously without lighting, the flame is yellow instead of blue, or the flame is uneven.

• The Technical Reality: This often indicates clogged burner ports, a failing spark module, or a misalignment in the gas/air mixture. A yellow flame suggests incomplete combustion, which can lead to carbon monoxide buildup.

2. Thermal Inconsistency (Oven Not Heating)

• The Symptom: The oven takes too long to preheat, burns food on the outside while leaving the inside raw, or fails to heat entirely.

• The Technical Reality: This signals a failure in the bake element, a recalibrated thermostat, or a faulty temperature sensor. Without precise thermal regulation, the cooking process is compromised.

3. Gas Odors or Hissing Sounds

• The Symptom: A faint smell of gas near the appliance or a subtle hissing sound when the unit is off.

• The Technical Reality: Critical Safety Alert. This suggests a degraded valve seal or a loose connection in the internal supply line. This requires immediate, specialized maintenance and technical support to ensure household safety.

4. Digital Errors & Control Panel Faults

• The Symptom: The digital display is unresponsive, the timer malfunctions, or cryptic error codes flash on the screen.

• The Technical Reality: Modern ranges are complex thermal computers. These codes signal logic board errors or safety lock malfunctions that require specialized diagnostics to decode and reset.
