You have that BBQ planned and you went to turn on your grill and it's not working. Do not panic! This guide will go over some of the more common issues that may occur with your gas grill.
Here are some expert troubleshooting tips when your gas grill just won't work right.
A low flame on grill is one of the top grill service issues we come across. Most 20 lb (BBQ) propane tanks are equipped with an OPD (overfill protection device) valve that prevents not only the grill from being overfilled but also from releasing gas if it senses gas trapped in the line or manifold. We find that once the tank is reset, the flame pattern returns to normal. Also, the LP (liquid propane) regulator can go bad as well.
Do you get an even flame pattern if you manually light your burner? If no, Are your burner holes clear of any soot and debris? If yes, clean out the burner or venturi tubes to be sure there are no spider webs.
To troubleshoot the LP Tank gas grill low flame issue follow these steps:
It's relatively common to find spiders and insects your burners. These pesky critters cause the gas to flow from the front of the burner. This is a very dangerous situation as it can cause a fire behind the valve panel as well as damaging the grill thus making it unsafe to operate. You should inspect and clean the burners at least once a year or immediately if any of the following conditions occur:
There are many reasons why a grill will not light, but the most common reason is the spark generator. If you're having an issue igniting your grill, try to light it manually. If it will ignite manually, there is an issue with the ignition system.
There a 3 common types of spark generators in a grill
See if burner can be manually lit with match or lighter. Are the other burners in the grill igniting? Check for any cracks in the ceramic tube or breaks in metal tip as well as be sure to look at the alignment of the metal tip on the electrode to the burner.
Access the grills electrode igniters by removing the cooking grates and heat shields. The electrode may be housed in a collector box.
When you press your ignition switch you should hear a rapid clicking (in a battery spark generator) or hard snap (in a piezo style igniter) as well as you should see a spark at the end of the electrode tip. You may need to get a flat head screw driver and place it under the metal tip.

In a gas grill you want your flame to be blue with yellow tips. If you have yellow or orange flames, this is a sign where there may not be a good mixture of air and gas or there may be insects or an obstruction in the burner.
1. Check the burner inlet for obstruction…ex. Spiders, insects, etc.
The air adjustment can be found by the bottom burner or if your burner uses venturi tubes, at the base of the tubes. If your gas grill is generating yellow or orange flame, you should adjust the air shutter by following these steps:
(If you have a cast iron or cast brass burner (as on Lynx Grills), you may find the air shutter at the bottom of the burner. Follow the same steps above.)
A yellow and orange flame can also be caused by an incorrect gas type on the orifice. If the grill is set for natural gas and you are trying to use propane, this can cause too much gas to come from the orifice nozzle and can create a yellow flame.
Check for spiders or other insects, Debris inside burner or Air mixture. If you have an infrared burner, check for cracks in the ceramic.
If you smell gas, you would want to turn off the gas supply and find the source.
Make sure that the orifice on the grill is for the correct gas type
Flare ups can be caused by a variety of reasons. If your grill is experiencing an extensive amount of smoke or flare-ups, this is most likely caused by excess grease in the grill. Check your grills burner and flame disbursement system (flame tamers, heat plates, briquette trays, etc) for any metal failure or soft spots.
Periodically clean all the guts in your grill.
