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

Technical Background:

The air shutter controls the amount of air that mixes with the gas before combustion. The ideal ratio of air to gas is critical for a clean, efficient blue flame. Restricted airflow creates a yellow flame.

Symptoms:

The homeowner observes that the flame on their Hotpoint range burner is predominantly yellow instead of blue. This indicates incomplete combustion, which can lead to carbon monoxide production and inefficient heating.

Possible Causes:

Insufficient air mixing with gas due to closed or misadjusted air shutter.
Obstruction in the burner ports, hindering proper airflow.
Low gas pressure affecting the air-fuel mixture.
Incorrect burner cap placement or damage.
Spiders or insects nesting in the burner assembly.
Blockage in the gas line itself.

Solution:

1

Turn off the range at the breaker panel. Allow the burners to cool completely.
2

Locate the air shutter near the burner tube at the front of the burner. It is usually secured with a screw.
3

Loosen the screw that secures the air shutter using a flathead screwdriver.
4

Carefully turn the range back on at the breaker. Ignite the burner.
5

While the burner is operating, gradually open the air shutter by rotating it until the flame turns blue with a slight yellow tip. Observe the flame color closely. A yellow tip is acceptable but the bulk of the flame should be blue.
6

Once the flame is properly adjusted, tighten the screw to secure the air shutter in place. Turn off the burner and allow it to cool again.
7

Turn the range back off at the breaker panel. If the flame remains yellow, clean the burner ports using a stiff wire brush or a specialized burner cleaning tool. Ensure all ports are clear of debris.

Safety Warning:

Disconnect power to the range at the breaker panel before performing any maintenance. Natural gas is flammable and can be explosive. Ensure adequate ventilation while working on gas appliances. If you smell gas, evacuate the area immediately and contact a qualified technician.

Prevention:

Regularly clean the burner caps and burner heads. Visually inspect the burner ports for blockages. Annually check the burner flame color and adjust the air shutter as needed. If you smell gas, leave the premises immediately and call the gas company.

Expert Tip:

Use a small mirror and a flashlight to inspect the burner ports underneath the burner head, this helps identify any hidden blockages that may not be visible from above. Also, note the position of the air shutter before adjustment so you can return to the original setting if needed.

Frequently Asked Questions

•What tools are required to adjust the air shutter?

You will need a flathead screwdriver to loosen the screw securing the air shutter. A wire brush or burner cleaning tool may also be needed to clean the burner ports.

•How do I clean the burner ports effectively?

Use a stiff wire brush or a specialized burner cleaning tool to gently scrub away any debris or buildup in the burner ports. Ensure that all ports are clear of obstructions.

•What should I do if adjusting the air shutter doesn't solve the yellow flame issue?

If the yellow flame persists, check the gas pressure using a manometer. Low gas pressure can affect the air-fuel mixture. If the pressure is low, contact a qualified gas technician.
