Did you know that the color of your gas range flame could indicate if repairs are needed? GE range oven parts and other brands may not be a requirement if all you need is a simple adjustment to the range's air shutter. 1. Turn on the burners on your gas range. 2. Observe the color of the flame. 3. Do you see a steady blue flame? Your range is fine and needs no adjustment to the gas flow or air shutter. 4. Is the flame yellow? You need to check the air shutter and the gas flow. If the air shutter needs opening, adjust this first and check the quality of your flame once more. If it is still yellow, check the gas flow. These fixes should do the trick, and you can save the purchase of Jennair parts for the next repair job.
