Whirlpool Gas Oven: orange flame
What is this symptom?
If your Whirlpool gas oven flame appears orange instead of the normal blue, it indicates potential issues such as incomplete combustion. This can result from an improper air-to-gas mixture, clogged burner ports, or environmental factors. Addressing this symptom promptly is crucial for safe and efficient operation.
Important Tips for Whirlpool Models
- Whirlpool official guidance for LP (propane) and converted models notes that improper flame color can result from clogged ports, misaligned burner caps, and influences like ultrasonic humidifiers and recommends proper seating of burner caps and checking gas/air mix.
