Four problems sit above the rest of this page, because what they put at risk is whoever is standing at the grate, the siding a few feet away and the tank under the cart, not the dinner. A smell of gas at the grill, along the hose or around the tank: turn every knob off, close the tank valve or the gas shutoff, leave the lid up so nothing collects under it, strike no match and use no switch nearby, walk everyone back, and call the gas utility or 911 from a distance if the smell hangs on. A grease fire that keeps going after the knobs are down: shut the gas at the tank or shutoff and turn the knobs off, lower the lid only if you can do it without leaning over the flames, keep every drop of water off it, and call 911 the moment it reaches the cart, the island or the house. Flame licking out behind the control panel or around the knobs: close the gas at the tank or shutoff, step back and let what is left in the line burn away; a spider nest in a burner tube is the usual reason. A knob that turns to off while its burner keeps burning: close the gas at the tank or shutoff and keep it closed. In every one of the four, the fittings, the valves and the hose stay untouched until a technician is there.

Gas or fire at the grill

Grill Gas Smell at the Burners or the Tank: What to Do Now

A gas smell from grill burners, the hose or the propane tank is the sharp added odor of propane or natural gas, noticed with the lid up, while lighting, or with every knob already off.

  1. A burner turned on that never litno repair
  2. Tank coupling not seated after an exchangelowest
  3. Regulator vent plugged or regulator failinglow to moderate

Grease Fire in the Grill That Won't Die Down

A grease fire in grill fireboxes is flame that keeps burning after the food is off: a blaze from the drip tray, a sheet of fire under the grates, or thick smoke pouring out around the lid.

Causes, cheapest first

  1. Grease tray and cup left full for monthsno repair
  2. Fatty food cooked over every burner on highno repair

Grill Flashback: Flames Behind the Knobs or Under the Panel

Grill flashback is flame burning where it should not: behind the control panel, around the knobs or at the front ends of the burner tubes, often with a soft roar, a hot panel or melting knobs.

Causes, cheapest first

  1. Burners run in a strong crosswindno repair

Grill Knob Won't Turn Off: Burner Still Lit at Off

A grill knob won't turn off when the burner keeps burning with the pointer at off, the knob spins round without stopping, or it jams partway while a flame stays lit under the grate.

Causes, cheapest first

  1. Knob stripped on the valve stemlowest
  2. The rear burner valve sticking from disuselow to moderate

Everything else we are called out for

None of the problems on these pages puts anyone in danger. The igniter may need four clicks where it once needed one, the flame may burn soft and yellow at the tips, the back left corner may never sear, the rotisserie may stall halfway round, or the pellet grill may wander a few degrees either side of its setting, and each of those can wait for a regular appointment. Every page lists what you can check at the grill with the gas closed and the grates cool before anyone drives out.

The repairs behind them

Gas Grill Won't Light: Knob On, Clicking, No Flame

A gas grill won't light when the knob turns and the igniter clicks yet no flame appears, or when one burner catches and the others stay dark beside it. 7 causes

Grill Igniter Not Sparking or Clicking Weakly

A grill igniter not sparking gives a dead button, a faint click with no visible spark, a spark that jumps to the wrong spot, or a hot-surface igniter that never glows orange. 7 causes

Grill Low Flame: Burners Stuck at a Weak Blue Line

A grill low flame is a burner that lights but sits as a short, weak line of blue even with the knob on high, so the grates never climb to searing heat. 6 causes

Grill Uneven Heat: Hot Spots and Cold Corners on the Grates

Grill uneven heat shows as steaks charred on the left and pale on the right, a cold front edge, or one corner that never browns while the rest of the grates run hot. 6 causes

Grill Yellow Flame and Soot on the Grates

A grill yellow flame burns tall, lazy and orange instead of crisp blue, and often leaves black soot on the grates, the underside of the lid and the food. 5 causes

Grill Not Getting Hot Enough to Sear

A grill not getting hot enough preheats for twenty minutes with the lid down and still reads low on the lid dial, leaving steaks gray instead of crusted. 6 causes

Grill Flare-Ups Every Time Food Hits the Grates

Grill flare ups are sudden bursts of flame that leap through the grates when fat drips, char the outside of food, and die down within seconds once the dripping stops. 6 causes

Pellet Grill Not Feeding: Full Hopper, Starving Fire

A pellet grill not feeding leaves a full hopper while the fire starves: the auger turns without moving pellets, stops with a hum, or the firepot sits empty while the display reads low. 6 causes

Pellet Grill Temperature Swings Far From the Set Point

Pellet grill temperature swings are readings that climb or fall far from the set point, flameouts where the fire dies mid-cook, or overshoots that scorch the food. 6 causes

Grill Rotisserie Not Turning or Stalling Under Load

A grill rotisserie not turning leaves the spit still, rocking back and forth, or slipping inside the food while the motor hums, clicks or stays silent. 6 causes

Grill Lights Not Working: Dark Knob Lights and Hood Lamps

Grill lights not working means dark knob lights on the control panel, a halogen or LED lamp inside the hood that no longer glows, or lights that flicker only in damp weather. 6 causes

Grill Burners Rusted Through: Holes, Gaps and Ragged Flames

Grill burners rusted through show as ports widened into slots, holes along the tube, flame jetting sideways from a gap, or flakes of rust falling into the tray. 6 causes

Grill Error Code on a Pellet Controller or Digital Panel

A grill error code shows as letters and numbers on a pellet grill controller, a flashing light on a digital control panel, or an alert in the maker's app paired with the grill. 7 causes

Not every grill
breaks the same way.

A built-in gas grill head sits in a counter cutout on its own gas line; a freestanding gas grill rolls on a cart, usually with a propane tank below; an infrared grill puts a ceramic or mesh burner under the grate for fierce, direct heat; and a pellet or hybrid grill feeds wood pellets into a firepot with an auger and a fan, or lets charcoal share the firebox with gas. Which one is yours?

All grill types
A large stainless built-in gas grill head set into a stone island on a sunny patio, its hood raised to show three burners glowing with even blue flame under clean stainless grates, the knob panel below with knobs, the access doors under the grill closed, plants softly blurred behind, daylight, seasonless.

Built-in gas grill

A stainless grill head dropped into a masonry or steel island, fed by a tank or the house gas line, with its burners, knobs and lid working in open weather.

 A stainless freestanding gas grill on a four-wheeled cart standing on a clean stone patio, its hood open over bare stainless grates with a soft blue burner glow beneath, side shelves folded out and empty, the cabinet doors below closed, a lawn and shrubs softly blurred behind, daylight, seasonless.

Freestanding gas grill

A gas grill on its own cart with wheels, side shelves and a propane tank below, or a hose to a house gas outlet, rolled into place on the patio.

 Close view of an open stainless grill with one infrared sear burner glowing bright orange across its honeycombed ceramic face under a heavy stainless grate, blue-flame burners beside it, the grill's hood raised on a patio, background softly blurred, daylight, seasonless.

Infrared grill

Grills that cook with radiant heat: ceramic or mesh infrared burners, sear stations beside the main burners, and radiant glass or emitter plates over a gas flame.

 A stainless pellet grill with its side hopper and a plain digital controller with a blank dark display, standing on a stone patio with its lid open, thin blue smoke rising from clean grates, the hopper lid closed, shrubs softly blurred behind, daylight, seasonless.

Pellet and hybrid grill

Pellet grills with a hopper, auger and electric igniter under a digital controller, and hybrids that burn gas, charcoal or wood in the same firebox.

Questions about
the problems.

My grill problem is not on the list. Can I still book?
Yes. The list follows what grill owners call about most, and anything else is just as welcome. Describe in the notes what you see, hear or smell at the grill, and the technician starts from there.
The grill runs low and one side stays cold. Which page first?
Open the page for the sign you noticed first. A weak flame and a cold side often share a cause, such as a regulator that dropped into its low-flow bypass, a venturi tube half blocked by a web or burner ports closed by rust, and each page links its related problems at the bottom.
Which grill problems cannot wait for a regular slot?
Four: a smell of gas at the grill, the hose or the tank, a grease fire that keeps burning with the knobs down, flame behind the control panel or around the knobs, and a knob that will not shut its burner off. Each of those pages carries a flag; a slow igniter, a yellow flame or a pellet grill that drifts can wait for the booked day.
Is food from a grill that lost its heat safe to eat?
It depends on the food and how far it got. Meat that was only partly cooked when the flame died should be finished right away on another heat source or thrown out, never set aside to finish later. Check the center with a food thermometer: USDA guidance puts whole cuts of beef, pork and lamb at 145 °F with a rest, ground meat at 160 °F and poultry at 165 °F.
