Amana Range Burner Yellow Flame: Adjusting the Air... | appliancefaults.com

Technical Background:

The burner flame color is directly related to the air-to-gas ratio. A yellow flame indicates insufficient air mixing, while a blue flame indicates proper combustion. The air shutter controls the amount of air drawn into the burner during operation. Gas pressure also affects the flame characteristics.

Symptoms:

The homeowner observes that the flame on their Amana range burner is predominantly yellow, instead of the desired blue flame. This can indicate incomplete combustion and may produce carbon monoxide.

Possible Causes:

Insufficient air mixing with the gas.
Blocked air shutter.
Debris in the burner ports.
Incorrect gas pressure.
Spider web or insect nest obstructing airflow.

Solution:

1

Turn off the gas supply to the range at the shut-off valve, usually located behind the range or in the basement/crawlspace. Use a wrench to ensure it's completely closed.
2

Locate the air shutter on the burner. It's usually a metal band or sleeve near where the burner attaches to the gas supply.
3

Loosen the screw or clip that secures the air shutter. A 1/4-inch nut driver may be required.
4

Adjust the air shutter by rotating it to increase the air intake. Observe the burner flame while making small adjustments.
5

Aim for a blue flame with a slight yellow tip. A completely blue flame indicates too much air, which can cause the burner to lift off the ports and be noisy.
6

Once the flame is adjusted correctly, tighten the screw or clip to secure the air shutter.
7

Turn the gas supply back on and test all burners to ensure proper operation. Check for gas leaks using a gas leak detector or soapy water solution. If leaks are found, call a qualified technician.

Safety Warning:

Lock Out/Tag Out (LOTO) the power supply to the range before performing any maintenance. Gas appliances can be dangerous. If you're not comfortable working with gas, call a qualified technician. Gas leaks can cause explosions and carbon monoxide poisoning.

Prevention:

Regularly clean the burner ports with a wire brush or needle to remove debris. Inspect the air shutter for obstructions. Schedule annual licensed technician range maintenance.

Expert Tip:

A slight orange flicker at the tips of the blue flames is normal due to mineral content in the gas. If the yellow flame persists after adjusting the air shutter, check the gas pressure with a manometer. A pressure of around 4 inches of water column is typical for natural gas.

Frequently Asked Questions

•What is the correct gas pressure for my Amana range?

Typically, natural gas ranges operate at a manifold pressure of 4 inches water column, while propane ranges operate at 10 inches water column. Consult the range's service manual for the specific pressure requirements for your model.

•How do I clean the burner ports on my Amana range?

Use a small wire brush, a sewing needle, or a specialized burner port cleaning tool to remove debris from the burner ports. Be careful not to enlarge the ports.

•What are the symptoms of a gas leak?

The most common symptom is the smell of rotten eggs or sulfur. Other symptoms include hissing sounds near gas lines, dead plants near gas lines, and increased gas bills.
