Why do you have a green flame on my home gas stove?

Gas flames are typically blue in colour. A green flame on a home gas stove indicates incomplete combustion, which can be associated with several factors:

Improper Air-Fuel Mixture: The stove's burner may be receiving an inadequate amount of air, leading to incomplete combustion. This scenario often occurs when the stove's air shutters are closed too much, restricting the oxygen supply.

Clogged or Obstructed Burner: The burner ports may be clogged or partially blocked with food residue, grease, or other debris, inhibiting the proper mixing of air and fuel. This obstruction prevents complete combustion and results in a green flame.

Damaged Thermocouple: The thermocouple, a safety device on the stove, can become faulty over time, leading to incorrect gas flow regulation. A malfunctioning thermocouple can disrupt the air-fuel ratio and cause the flame to turn green.

Low Gas Pressure: If the gas pressure in your home's gas line drops, it can affect the proper functioning of the stove burners, leading to incomplete combustion and a green flame.

Burner Design: Certain stove burners are designed to produce a green flame for aesthetic reasons. These burners use additives that emit a green glow when the flame is lit. However, if you notice a sudden change in the flame colour, it's important to address the underlying cause.

To resolve the green flame issue, try the following steps:

1. Check the air-fuel mixture: Make sure the air shutters on the burner are open to allow sufficient airflow.

2. Clean the burners: Thoroughly clean the burner ports and remove any debris or blockages.

3. Inspect the thermocouple: If you suspect a faulty thermocouple, contact a professional for inspection and replacement if necessary.

4. Check gas pressure: If you notice the green flame on multiple burners, it's worth getting your home's gas pressure checked by a professional.

5. Contact the manufacturer: Refer to the stove's user manual for specific instructions and troubleshooting advice from the manufacturer. If you're uncertain about any repairs or adjustments, always consult a qualified technician or consult your stove's user manual for further instructions.
