Reasons Why You Have to Light Your Gas Grill Manually

A Faulty Igniter | Faulty or Dead Ignition Battery | Poor Connections | Blocked or Dirty Burner Tubes | Ignitors May Not Be Included With the Grill

There are several reasons why you might find yourself needing to light your gas grill manually.

While modern gas grills often come equipped with an automatic ignition system for convenience and ease of use, there are instances where manual lighting becomes necessary.

Whether it’s due to a malfunctioning igniter, a faulty or dead battery, or simply the absence of an automatic ignition system in older models, understanding how to manually light your gas grill will save your cookout in a pinch.

Thankfully there are only a few common reasons why you’ll need to manually light your gas grill, and they’re usually easy to fix!

A Faulty Igniter

A faulty igniter is one of the most common reasons why a gas grill may not light automatically.

The role of the igniter, also known as the spark generator, is to create the spark which ignites the gas in your grill. When you push the ignition button, an electrical impulse is transmitted to the igniter, triggering a spark. This spark reacts with the gas, setting it alight and getting your grill going.

However, if the igniter is faulty, it may not be able to generate the necessary spark. This could be due to a variety of reasons including normal wear and tear, exposure to damp conditions, or an accumulation of grease and dirt.

In some cases, the issue might be with the wiring that links the ignition button to the igniter. The damage or disconnection could disrupt the electrical current, stopping it from reaching the igniter.

Faulty or Dead Ignition Battery

The first thing to check is to see if your grill has a battery igniter. A faulty or dead ignition battery can prevent your gas grill from lighting because it prevents it from creating a spark. When you press the ignition button, the battery provides the electrical charge that is sent to the igniter, which then generates the spark needed to ignite the gas.

If the battery is dead or malfunctioning, it cannot generate the necessary charge. Without this charge, no spark can be created. This means that no matter how many times you press the ignition button, your grill isn’t going to light.

Faulty batteries may not provide a consistent charge, leading to intermittent or weak sparks that may not be enough to ignite the gas. Dead batteries, on the other hand, will not provide any charge at all.

In both cases, the result is the same: the grill will not light automatically and the battery needs to be replaced.

Poor Connections

Poor connections to the ignition system can also prevent your gas grill from lighting. This is because the ignition process relies on a series of interconnected components all working together to generate the spark that ignites the gas in the grill.

The ignition button sends an electrical signal via wires to the spark generator (or igniter). This igniter then generates a spark, which travels to the gas in the burners to create the flame needed for grilling.

If there’s a loose or corroded connection anywhere in this chain, the electrical signal could be interrupted or weakened. This could prevent the igniter from producing a spark or make the spark too weak to ignite the gas.

As a result, despite having good gas flow and a functioning igniter, the grill may not light if the connections within the ignition system are not secure and in good condition.

Blocked or Dirty Burner Tubes

Blocked or dirty burner tubes can prevent your gas grill from lighting due to the obstruction in the gas flow pathway. Burner tubes are responsible for delivering the gas from the regulator to the burners, where it then mixes with air and ignites to produce a flame.

Over time, grease, food particles, and other debris can accumulate in the burner tubes. If left uncleaned, these materials can solidify or cause rusting, leading to partial or complete blockages in the tubes.

Insects such as spiders may find the tubes an attractive place to nest, which can also cause blockage.

When the burner tubes are blocked or dirty, the gas cannot flow freely. Without the proper gas flow, the igniter may not be able to produce a spark strong enough to ignite the limited amount of gas reaching the burners.

Ignitors May Not Be Included With the Grill

While it’s rare nowadays, a few grills may still be out there without a built-in ignition system and manual lighting is a must.

The more likely reason is when you inherit or purchase a used or older grill and the ignitor system no longer works.

In both cases, the only workaround is to manually light the grill.

What You Need to Manually Light Your Gas Grill

You don’t need much in the way of special materials to manually light your gas grill. Just make sure your grill is located in a well-ventilated area and have the following items:

• Long matches, or
• Long-handled grill lighter
• Fire extinguisher or water source (it never hurts to keep these items on hand when using a grill of any kind.)

As I said, nothing fancy is needed.

How to Manually Light a Gas Grill

Liquid Propane Grills | Natural Gas Grills

Manually lighting a gas grill is a skill that comes in handy, especially if the grill’s automatic igniter fails or if you own an older model without an ignition system.

So if you’re ready to start cooking, use the simple step-by-step instructions I outline below to get your barbecue started.

Liquid Propane Grills

Lighting a Liquid Propane (LP) grill manually is straightforward, but it should always be done with attention to safety.

Here’s a step-by-step walkthrough for lighting a liquid propane gas grill manually:

1. Open the Lid: Always keep the lid open during the lighting process to prevent gas from building up inside the grill.
2. Make Sure All Burners Are Turned Off: Make sure that all control knobs are in the “off” position.
3. Turn On the Gas: Slowly open the valve on the propane tank to allow gas to flow into the grill’s lines.
4. Wait for a Few Seconds: Allow a moment for the gas to fill the lines and reach the burners.
5. Light a Long Match or Grill Lighter: Using a long match or grill-specific lighter, ignite the flame.
6. Turn On the Burner Closest to You: Turn the control knob of the burner closest to you to the “high” setting.
7. Light the Burner: Immediately insert the lit match or lighter into the hole at the bottom of the grill (often called the manual lighting hole) that leads to the burner. If your grill does not have a manual lighting hole, put the flame down through the cooking grates close to the burner.
8. Check for Ignition: You should hear a whooshing sound as the gas ignites and see the burner’s flames. If it does not light within a few seconds, turn off the gas, wait for a minute or two to allow any accumulated gas to disperse, and repeat the above steps.
9. Light Other Burners: If your grill has multiple burners, you can now turn them on using the control knobs. They should ignite from the flame of the already lit burner.

Always refer to your grill’s manual, as different grills might have slightly different procedures for manual lighting.

Natural Gas Grills

Lighting a Natural Gas Grill manually involves a similar process to lighting a Liquid Propane Grill but with a few differences due to the source of the fuel.

Here’s a step-by-step walkthrough for lighting a natural gas grill manually:

1. Open the Lid: Keep the lid open during the lighting process to prevent gas from accumulating inside the grill.
2. Make Sure All Burners Are Turned Off: Ensure that all control knobs are in the “off” position.
3. Turn On the Gas Supply: Locate the gas shutoff valve that supplies the grill, and turn it to the “on” position.
4. Wait for a Few Seconds: Give the gas a moment to flow through the lines and reach the burners.
5. Light a Long Match or Grill Lighter: Ignite the flame using a long match or a grill-specific lighter.
6. Turn On the Burner Closest to You: Turn the control knob of the burner nearest to you to the “high” setting.
7. Light the Burner: Insert the lit match or lighter into the manual lighting hole or through the cooking grates, following the specific location recommended in your grill’s manual.
8. Check for Ignition: Look for the flames and listen for the sound of ignition. If it doesn’t light within a few seconds, turn off the gas, wait for any accumulated gas to disperse, and repeat the steps above.
9. Light Other Burners: If your grill has multiple burners, you can now turn them on using the control knobs. They should ignite from the flame of the first lit burner.

Once again, always consult your grill’s manual, as there may be slight variations depending on the brand and model of your grill.

What to Do if Your Grill Still Doesn’t Light

If you didn’t succeed in lighting the grill manually the first time, turn off the control knobs and gas supply and wait five minutes. Let the gas disperse and then try again.

If your gas grill still won’t light even after trying to light it manually, you should consider the following steps:

• Check the Gas Supply: Make sure that the propane tank is not empty and that the gas line is properly connected and turned on.
• Light Another Burner: Try lighting another burner as the first one may be the problem.
• Inspect the Burner Tubes: Look for any blockages, dirt, or grease that may be preventing the gas from flowing.
• Consult the Manufacturer’s Manual: Follow any specific troubleshooting steps provided by the manufacturer for your particular grill model.
• Contact a Professional: If you’re still unable to light the grill, it may be time to contact a professional technician or the grill’s manufacturer for assistance. There may be underlying issues that require expert attention.
• Consider a Replacement: If the grill is old and repair costs are high, it may be more economical to replace the grill with a new one.

Always prioritize safety, and if you’re unsure, seek professional assistance rather than attempting further repairs on your own.

Safety Tips for Lighting a Gas Grill Manually
