Write down what you saw. Any gas odor, fire near the knobs or a control that keeps gas flowing ends the checks. By [BBQGrillRepair.center technical team](https://bbqgrillrepair.center/authors/technical-team/) Published September 26, 2026 ## At a glance. A visit goes faster, and sometimes becomes unnecessary, when the owner has already ruled out the tank, the outlet and the grease tray. This is the order we would walk through ourselves, while the grill is cool and its gas is shut between attempts. Read the whole guide ### Time needed About fifteen minutes Most of it spent looking, not taking anything apart. ### Tools Flashlight, phone camera, small mirror No wrench: fittings are not part of these checks. ### Lights or a controller dead Power off five minutes, then back on Lynx's reset for a transformer that shut itself down. ### Hose check Soapy water, only as the manual says NFPA suggests it on the tank hose before the first cook each year. In this guide 1. Start with what the grill is 2. Walk the gas path from the tank to the knobs 3. Power, batteries and the spark 4. The grease tray and one burner's flame 5. Step by step 6. Questions ## Start with what the grill is Find the rating label and photograph it. It names the maker and model, carries the serial, states which fuel the burners were set up for, and answers half the questions a scheduler asks. On many built-in heads it hangs under the drip tray; our guide on finding the grill rating label covers the other places makers put it. Then note what kind of grill it is and how it is fed: a cart grill on a portable cylinder, a built-in head on a natural gas line or a larger fixed propane tank, an infrared sear station, or a pellet or hybrid grill that plugs in. Each has its own short list below. - Maker, model and serial number from the label. - Gas type on the label, and the gas you actually burn. - What happens, in one sentence: does not light, low heat, uneven heat, a code, no lights. - When it started: after a tank swap, a storm, a cleaning, a move or a long idle season. Source: [Lynx — Troubleshooting](https://www.lynxgrills.com/troubleshooting) — The serial rating plate is usually under the drip tray ## Walk the gas path from the tank to the knobs Begin at the source. On a portable cylinder, lift it or weigh it; a nearly empty one can light a burner and still leave the grill cold. Confirm the cylinder valve has been turned open and the regulator's coupling is threaded fully on, hand-tight, as it was when the tank went on. On a natural gas grill, find the shutoff near the grill and confirm the handle lies along the pipe. Follow the hose with a flashlight. Look for cracks, a crushed section under a wheel, a spot touching a hot panel, or a regulator pressing against the cart; Lynx asks that the regulator never touch the grill body because its diaphragm needs to move freely. If every knob was open when the tank was opened, reset the regulator before going further. ### The soapy water check on the hose NFPA's tip sheet suggests brushing a light soap and water solution along the tank hose before the first cook each year; a leak blows bubbles. Do it only if your own manual calls for it, with every flame and cigarette far away. If bubbles appear and there is no flame, close the tank and the grill knobs; if the leak stops, NFPA says to have the grill serviced before using it again, and if it will not stop, to call the fire department.

Plug a lamp into the same outlet, and if the outlet has test and reset buttons, press reset. Lynx's advice when the lights stay dark is to disconnect power, wait five minutes for the transformer to cool and reset, then reconnect. For a battery igniter, open the cap on the front panel and fit a fresh cell the way the diagram shows. For a piezo button, listen for the snap. For hot-surface igniters, Lynx has owners hold a knob in at off and look for the glow with a small mirror. A pellet grill that shows a code on its display has told you where to look; note the code exactly and read our error code pages. ### Three extra looks at a pellet grill Open the hopper and check that pellets reach the bottom of the chute and are dry and hard, not swollen into sawdust. Listen during startup for the auger motor and the fan. And with the grill unplugged and completely cold, look at the firepot; one heaped with ash or unburned pellets explains a failed start on its own.

A tray brimming with fat is both a fire risk and a common reason for smoke and flare-ups; NFPA's tip sheet asks owners to remove grease buildup from the grill and the trays below it. While the tray is out, shine the flashlight upward at the burners for rust flakes or a burner that has dropped out of its bracket. Last, lift the grates, light a single burner by the manual's procedure and look at the flame for a minute. Short and blue is good news. Tall and yellow, lifting off the ports, or dark in patches along the burner each has its own guide on this site. ### What to send with the booking Two photos and three lines are plenty: the rating label, the burners with the grates lifted, and a note of what you checked and what you saw. A technician who knows the tank is full, the outlet is live and the tray is clean can go straight to the burner, valve, igniter or controller that is left. ### Four signs that end the checks at once Gas you can smell near the grill or the cylinder, grease still burning after the burners are off, flame or scorch marks around the knobs, or a knob that keeps gas flowing at off. For any of them, shut the supply at the cylinder or the line valve if you can reach it safely, keep the hood up for an odor and clear of the fire, and move back. If the odor lingers or the fire grows, phone 911 or the gas utility from well away. - Gas odor: controls off, supply shut, hood up, nothing lit, everyone away. - Burning grease: supply shut, controls off, hood lowered only when that is safe, no water on it. - Fire around the control panel: supply shut at the source, then distance. - A control that will not turn the gas off: the cylinder or line valve stays shut until the visit.

Nothing past the cylinder coupling gets loosened, no valve or orifice is removed, no leak is looked for with a flame, the wiring behind the panel is left alone, and nobody reaches into a pellet firepot that is still warm.

Five steps, in the order worth doing them. 01 ### Photograph the label Model, serial number and gas type, in focus, before anything else. 02 ### Check the fuel Weigh or lift the cylinder, open its valve slowly, or confirm the natural gas shutoff is open. 03 ### Check power Test the outlet with a lamp, press its reset button, then power the grill off for five minutes and back on. 04 ### Check the spark and the tray Fresh igniter battery, a snap or glow at each burner, and an empty drip tray. 05 ### Watch one flame Grates lifted, one burner lit on high, and a photo of what the flame looks like. For the heart of your home. ## Questions owners ask. ### Do I need to disconnect the tank to do these checks? No. Close its valve between steps and open it slowly when you want a burner lit. Removing the tank coupling is not needed for anything on this list. ### The grill lights fine but the lights and rotisserie are dead. Is that a gas problem? No, that is the electrical side. Test the outlet, reset it, and give the grill five minutes unplugged. If the lights stay dark, book the electronics rather than the burners. ### Should I clean the burners before the visit? Empty the tray and brush the grates if you like, but leave the burners as they are. Their condition is part of what the technician needs to see. ### What if the controller shows a code I cannot find? Write it down exactly as it appears, including letters and dashes, and send a photo. Codes differ between makers and even between models of the same maker. ## The problems behind it. Each has a page of its own: what it usually means and the causes in the order worth checking. [All 17 problems](https://bbqgrillrepair.center/problems/) Problem ### Gas Grill Won't Light: Knob On, Clicking, No Flame 7 causes, cheapest first Problem ### Grill Not Getting Hot Enough to Sear 6 causes, cheapest first Problem ### Grill Lights Not Working: Dark Knob Lights and Hood Lamps 6 causes, cheapest first Problem ### Grill Error Code on a Pellet Controller or Digital Panel 7 causes, cheapest first Gas or fire at the grill ### Grill Gas Smell at the Burners or the Tank: What to Do Now 6 causes, cheapest first ## When it needs a technician. The repairs on the right are where this guide ends when the checks do not settle it. ### Grill diagnostic visit One visit to find why the grill will not light, heat or hold its flame: gas supply, burners, igniters, valves and any controller, each checked. ### Grill cleaning and safety inspection A deep grill cleaning with the burners out, venturi tubes cleared, grease path scraped, gas supply leak-checked and every flame read before the season. ### Grill lights and electronics repair Hood lights, knob lights, transformers, power supplies and digital displays on a grill that have gone dark, flicker or trip the outlet, found and fixed. ### Grill igniter repair No spark, a weak spark or a spark in the wrong place: the grill's battery module, piezo button, electrodes, wires and hot-surface igniters tested and fixed. ## More in troubleshooting. The checks a grill owner can make safely, from the tank valve, the regulator reset and the igniter battery to the electrode gap, the grease tray and the rating label, and where to stop and book.
