Gas ranges

Burners act strangely after a new range installation

Ignition or flame problems right after a new installation usually trace back to setup details like the gas type, connection, or shipping materials rather than a defective unit.

Symptoms

  • Problems started immediately after delivery and installation
  • May affect ignition, flame size, or flame color
  • Range worked fine in the store or seemed fine on delivery
  • Installer may have connected the gas line themselves

Likely causes

  • CommonRange set up for the wrong gas type (natural gas vs. propane)Ranges usually ship configured for natural gas and need a conversion kit for propane, or vice versa.
  • CommonShipping materials or tape left on burners or ignitersProtective tape or foam is sometimes overlooked during unboxing.
  • PossibleGas connection not fully open or improperly connectedA newly connected line may have a valve not fully opened or a loose fitting.
  • Less commonRange simply needs the anti-tip bracket and leveling done before it sits and seals correctlyAn unlevel range can occasionally affect how components seat.

What to do

  1. Check your range's specification label or manual to confirm it's configured for the gas type actually supplied to your home.
  2. Look closely at all burners and the oven interior for leftover tape, foam, or plastic film from packaging.
  3. Confirm with the installer or your own inspection that the gas line connection is snug and the shutoff valve is fully open.
  4. Test each burner and the oven individually, noting any pattern to the issues.
  5. If the gas type is wrong, do not attempt a conversion yourself; this requires a specific kit and professional installation.
  6. Contact the installer or a technician promptly if issues persist, since this may be a warranty issue on a new appliance.

When to call a pro

If the range was installed by a professional, contact them to correct the installation; otherwise call a licensed technician, especially for any gas-type mismatch.

Safety

Use caution

Never attempt a natural gas to propane conversion yourself; this requires the correct kit and a licensed installer.
