Grill season is quickly approaching. If your grill has been sitting or even getting an increased use, parts will eventually fail. We will explore some common issues we come across when servicing grills.
You have that BBQ planned and you went to turn on your grill and it is not working. Do not panic! This guide will go over some of the more common issues that may occur with your gas grill.
A Low flame on grill is one of the top grill service issues we come across. Most 20lb (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 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.
If you are having an issue igniting your grill try to light it manually. If it will ignite manually, there is an issue with the ignition system (and not a gas related issue). If it will not ignite manually, you may have a clogged orifice, a potential manifold failure or regulator may be bad.
There a number of types of ignition styles in a grill. Here are a few popular types:
You can get to the igniters by pulling off the cooking grates and the barrier and thus exposing the burners. Try to locate the position of the igniters (generally, at the root end of the burner) and push the ignition button. You should see a small spark or hear the sound of a click (Or a stream of clicks in case of electric smokers) if your grill machine has piezo-electric or push button igniters. If your igniter is jammed, clean it very carefully and recheck it. Consider replacing the batteries if deemed necessary.
Uneven heating is a problem that can result from breaks or holes in a burner or a damaged flame dispersing part such as a heat shield or briquette tray. You have to remove your burner and inspect your burner for any holes. Also be sure the burner port holes are free and clear of debris. If any of the burner ports are clogged, take a small drill bit and clear each port. Be sure to shake out any debris that may have fallen inside the burner.
Check your grills flame disbursement system (flame tamers, heat plates, briquette trays, etc) for any metal failure or soft spots.
4. Orange or Yellow Flame
If you have yellow or orange flames, this is a sign where there may not be a good mixture of air and gas.
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.
If your grill is experiencing an extensive amount of smoke or flare-ups, this is most likely caused by excess grease in the grill.
Periodically clean all the guts in your grill. This involves removing and cleaning cooking grates, heat shields or briquette trays and burners. Take a shop vac and remove all the debris in the firebox. This can ignite when it comes in contact with drippings. Grill cleaning is a part of grill ownership and maintenance regardless of brand or type.
NOTE : Be sure to let the grill completely cool before performing any inspections!!
Inspect the burner tube to see if there are any spiderwebs in the venturi. This is the most common cause of flashbacks. Also, be sure that burner seats OVER the orifice.
These are some of the most frequent grill troubleshooting problems you might face with your grill.
