Why Is My Gas Stove Flame So Weak? How to Diagnose and Fix Your Problem

PRS Parts Inc. – Helping Hawaii Homes Cook with Confidence

If your gas stove isn’t giving you the strong, blue flame you’re used to, it could mean something is interfering with the gas flow or combustion process. A weak flame not only slows your cooking but can be a sign of a part needing cleaning or replacement.

Here’s how to quickly diagnose the issue—and how PRS Parts Inc. can help you fix it.

🔍 1. Check for Clogged Burner Ports

Over time, food, grease, or debris can clog the tiny holes (ports) where gas escapes and ignites.

Fix:

  • Turn off the stove.

  • Remove the burner cap and use a paperclip or stiff brush to clear each port.

  • Wash the cap with warm soapy water and dry thoroughly before reassembling.

🔧 2. Inspect the Burner Heads and Caps

Burner heads that are out of alignment or not seated properly can cause uneven or weak flames.

Fix:

  • Ensure the cap is centered and flat.

  • Check for any warping or damage—if so, you may need a replacement burner cap or head.

🌬️ 3. Look at the Gas Supply

A kinked gas line, improperly opened valve, or low gas pressure can all affect flame strength.

Fix:

  • Make sure your gas shutoff valve is fully open.

  • If using propane, check that the tank has fuel and that the regulator is functioning correctly.

  • For ongoing pressure issues, contact a gas technician to assess supply problems.

🧼 4. Clean or Replace the Igniter

A weak spark or delayed ignition can result in partial gas release, which won’t burn as strong.

Fix:

  • Clean the igniter tip gently with a toothbrush or cloth.

  • If it’s worn or damaged, PRS Parts Inc. carries OEM igniters compatible with most major brands.

⚙️ 5. Check the Air Shutter

The air shutter controls how much air mixes with the gas. Too much air can dilute the gas mixture, resulting in a small or yellow flame.

Fix:

  • Locate the air shutter beneath the burner.

  • Adjust it slightly to find the right flame balance: blue, steady, and about 1 inch tall.

  • If unsure, consult your stove’s manual or a technician.
