Gas Grill Troubleshooting Guide

A low flame can make it difficult to reach proper cooking temperatures, often resulting in undercooked food. This issue may be related to gas flow restrictions or regulator problems.

• Propane tank is low or nearly empty. Refill or replace the propane tank.
• Regulator needs to be reset. Turn off the gas at the tank and disconnect the hose. Turn all burner control valves to HIGH for one minute to purge any air, then turn them OFF and wait five minutes for any gas to clear. Reconnect the hose, slowly open the tank valve, and relight the grill as usual.
• Clogged burner ports. Ensure there is no debris or spiderwebs inside the burners, or burnt-on grease or food on the exterior, as they can clog the ports. Make sure the gas is turned off before removing the burners and use a stiff wire brush to clean them.

A grill that won’t light or stay lit can indicate issues with gas flow, ignition components, and blockages. This is a common issue that can often be quickly diagnosed.

• Empty or improperly connected propane tank. Ensure the tank is full and the valve is securely connected.
• Gas supply is turned off. Turn on the gas supply.
• Dead or dirty igniter. If you have an electric ignitor and there is no clicking, or the clicking is slow or faint, replace the battery. Carefully clean the ignitor if it's clogged or replace if it's damaged.
• Blockage in the gas system. Inspect the burners to be sure insects, spider webs, and rodent nests do not block them. Clean if necessary. Inspect the control panel to be sure the burners are aligned properly with the valves.
• Crimped or damaged fuel supply hose. Inspect and straighten or replace.
• Grill is in bypass mode. Turn off all burners, reset the regulator, and then slowly open the tank valve.

A grill that won’t stay lit may indicate airflow, gas supply, or component issues. It often starts and then goes out within seconds or minutes.

• Low fuel levels. Low fuel levels in the tank can lead to weak or sputtering flames. If the propane tank is nearly empty or malfunctioning, it is recommended to refill the tank with more propane or replace it entirely.
• Wind is blowing out the flame. Reposition the grill away from the wind or use a compatible wind guard.
• Clogged burners or venturi tubes. Clean the burners and ensure tubes are free from any obstructions.
• Faulty regulator. Try resetting the regulator or replace if necessary.

If your gas grill isn’t getting any gas, there are several possible causes. Here are some steps to help you identify and fix the issue:

• Check the propane tank or natural gas supply. Ensure that the propane tank is adequately filled or verify that the shut-off valve on the gas line is open and that the line has sufficient pressure. Additionally, confirm that the tank or gas line valve is fully opened.
• Reset the regulator. The regulator may be in bypass mode, which restricts gas flow.
• Check for hose blockages. Look for kinks, cracks, or damage in the hose that could block flow. 
• Check for gas leaks. Use a 50/50 solution of soap and water on the hose and other connection points to check for a leak. If bubbles form at any of the points, you’ve got a leak.
• Burners are clogged or misaligned. Clean out any debris or food buildup and realign burners with the valves if necessary.

Often, yellow or orange flames indicate an issue with the burners or venturi tubes. The good news is that these issues are usually related to spiderwebs and other blockages or a misalignment of the burners, which are all easy fixes.

• Venturi tubes are blocked. Check for debris or pests and clean.
• Burners have a high buildup of grease or dirt. Remove and clean the burners with a stiff wire brush.
• Burners are not aligned properly with the valves. Inspect and realign if necessary.
• Malfunctioning regulator. Reset your regulator or replace it.
