Gas Range Green or Yellow Burner Flames
Topics:
- Surface burners on R series gas range are producing green flames with an ammonia odor
- Why are gas burner flames yellow
- Cooktop, Range, and Rangetop surface burner producing green or yellow flames
Cause:
- Improper air / gas mixture
- Burner heads not seated properly
- Burner heads need cleaning
- Some LP flames have yellow or orange tipping normally
- Ammonia in gas line
Troubleshooting:
If the unit is LP Gas
- If the surface burners were recently cleaned with any type of chemical, rewash them with soap and water.
- Dry thoroughly before retesting.
- If it is more noticeable in colder weather, it may be due to LP gas settling based on weather conditions that can cause performance issues.
- If the issue only occurs early or late in the day and subsides in the afternoon, as temperatures warm, or after the burners have been in use for a period of time it may be due to the LP gas.
- Propane gas can settle based on weather conditions causing performance issues
- Verify the LP tank is not low on fuel
- Propane tanks operating at a low level of fuel can cause performance issues.
For LP and Natural Gas Models
- If the surface burners were recently cleaned with any type of chemical, rewash them with soap and water.
- Dry thoroughly before retesting.
- Verify the gas supply line is 3/4" rigid pipe
- If a copper line was used, it could be contributing to the discoloration of the flame.
