Quick answer

A grill not lighting usually comes down to four things: an empty or closed propane tank, a regulator stuck in low-flow mode, burner tubes blocked by webs or debris, or a dead igniter. Check the gas and reset the regulator first. If the grill lights by hand with a long lighter but the button does nothing, the igniter is dead, and a replacement kit swaps in about 10 minutes.

Free fix vs. permanent fix

Free fix · 15 minutes

Check the gas, reset the regulator, light by hand

  • Check the tank has propane and the tank valve is fully open
  • Reset the regulator by disconnecting and reconnecting the tank
  • Clear webs and debris from burner tubes and ports
  • Light by hand with a long lighter and the lid open

How long it lasts: Gets you cooking tonight. It will not bring a dead igniter back, so you keep lighting by hand.

A replacement grill igniter kit

If the burner lights by hand, your gas side is fine and the spark is the problem. Igniters die from grease, heat, moisture and corroded electrodes. A new kit gives the button a fresh spark, so you stop reaching over the burner with a flame.

What to get: Replacement grill igniter kit

How long it lasts: Years. You get a fresh spark module and electrode.

Why it happens

1

An empty tank or a partly closed valve

Propane tanks run out with no warning unless you use a gauge. A valve opened only partway can also starve the burners.

2

A regulator in low-flow mode

Many regulators have a safety device that limits the gas flow if the valve is opened too fast or a burner is on during connection. The result is a weak flame or none.

3

Blocked burner tubes or ports

Spiders and insects love to nest in burner tubes, and grease and rust clog the ports. Gas cannot reach the flame.

4

A weak battery or a dead igniter

Grease, moisture and heat corrode the electrode, crack the ceramic and loosen the wire. The click may sound normal, but no spark reaches the burner.

Do these in order, starting with the simplest.

  1. Check the gas supply and look for leaks

    Tool used: Soapy water in a spray bottle

    Lift the tank to feel its weight, or read a gauge. Open the tank valve fully. Brush soapy water on the hose and connections and watch for bubbles. A leak means do not light it.

  2. Reset the regulator

    Turn all burner knobs off and close the tank valve. Disconnect the regulator, reconnect it hand-tight, then open the tank valve slowly, about a quarter turn. Wait 30 seconds before lighting.

  3. Clear the burners

    Tool used: Wire brush or pipe cleaner

    Remove the grates and brush the ports. Push a pipe cleaner or brush through the burner tubes to clear webs and debris. Do this when the grill is cool and the gas is off.

  4. Swap the igniter battery

    Tool used: Fresh AA battery

    If your igniter has a battery, unscrew the cap at the button, replace it and check that the contacts are clean. If there is still no click, the igniter or the wire is at fault.

  5. Light by hand with the lid open

    Tool used: Long-neck lighter

    Open the lid first. Hold the lit lighter at the burner or the match-light hole, then turn the burner knob. Keep your face and arm back. If it does not light in a few seconds, turn the gas off and wait five minutes.

  6. Replace the igniter

    Tool used: Replacement grill igniter kit

    Turn the gas off and let the grill cool. Remove the old electrode and wire, mount the new electrode near the burner, connect the module and wires, and follow the kit's instructions.

When free fixes aren't enough

If the grill lights by hand but the button does nothing after a new battery, the igniter is worn out or the electrode is corroded. Lighting by hand for good is not a great plan, since you lean over the burner and a delayed light can flash. If it will not light by hand either, the problem is gas flow, not the igniter: check the regulator, the hose and the burner tubes. If you smell gas when you are not lighting it, close the tank valve and move away. If the smell does not stop, leave the area and call the fire department or your gas supplier.

How we picked: How we picked: this page is based on gas grill owner manuals, propane safety guidance, instructions from igniter kit makers, and what owners report in reviews. We do not test products by hand.

Gas side or spark side? A two-minute test

Open the lid, hold a lit long lighter at the burner and turn the knob. If it lights with a normal blue flame, the gas is fine and the igniter is the problem. If the flame is tiny, yellow or will not start, look at the tank, regulator and burner tubes before you buy a thing.

What to match when you buy an igniter

  • Burner count: one electrode per burner, and enough outlets on the module.
  • Type: battery push-button, rotary or spark-on-demand, to match your controls.
  • Electrode shape: compare it with the old one.
  • Wire length: each wire must reach its burner without stretching.

What to skip

Lighting with the lid closed or using lighter fluid

Never close the lid to light a gas grill. Gas builds up inside and can flash when it lights. Do not use lighter fluid on a gas grill, and do not keep clicking the igniter if you smell gas. Shut the tank valve and wait.

Frequently asked questions

Grill not igniting but I can hear it click: what is wrong?
A click with no flame means the spark is not reaching the gas, or there is no gas to light. Test by lighting by hand. If it lights, the spark is weak, so clean the electrode or replace the igniter. If it does not light, check the tank, the regulator and the burner tubes.
Grill not starting: is it the gas, the burner or the igniter?
Light by hand with the lid open. If it lights well, the igniter is the problem. If the flame is weak or will not light, the gas side is at fault: a low tank, a stuck regulator or blocked tubes.
How to fix grill igniter that has no spark?
Replace the battery if it uses one, wipe the electrode dry and clean it, and check that the wire is connected. The tip should sit close to the burner, a small gap, so check your manual. If there is still no spark, install a new igniter kit.
Is it safe to light a gas grill with a match?
Yes, if you follow your manual and keep the lid open. Use a long lighter or match holder, and keep your face back. If it does not light within a few seconds, turn the gas off and wait five minutes before trying again.
How can I tell if my grill has a gas leak?
Brush soapy water on the hose and connections with the gas on. Growing bubbles mean a leak. You may also smell gas or hear a hiss. Close the tank valve and do not use the grill until the part is replaced.
