You have got people coming over. The food is ready. You turn the knob and nothing happens. No click. No flame. Just silence. It is one of the most frustrating things that can happen right before a cookout and it seems to always happen at the worst possible time.

The good news is that most ignition problems are not as serious as they first seem. Built-in grills sit outside all year through heat, rain and grease buildup so small issues are very common. Before you call a technician or start worrying about a big repair bill there are a few simple things you can check yourself.

Start With Your Gas Supply

This is the first thing to check and you would be surprised how often it turns out to be the whole problem. If you are using propane, check the tank. A tank that is not completely empty can still be too low to create steady pressure for ignition. If your grill runs on natural gas make sure the shut off valve behind or under the unit is fully open. This is easy to miss especially if the grill has not been used in a while or was recently serviced.

Here is a quick way to tell if gas supply is the issue. Turn a knob and check if you can briefly smell gas when you open the lid. If you can smell it but it still will not light then gas is probably not the problem. If you cannot smell anything at all then start with the supply.

Check the Igniter Button or Switch

Most built-in grills use either a push button igniter or an electronic ignition that runs on a battery. Press the igniter button and listen carefully near the burner.

If you hear nothing at all the button itself or the wiring may have stopped working. If your grill uses batteries try replacing them first. You would be amazed how many ignition problems are solved by a fresh set of batteries. It takes two minutes and costs almost nothing.

If you hear clicking but still get no flame then the igniter is actually working fine. The problem is somewhere else and the next thing to check is the burner.

Clean Out the Burner Ports

This is the most common cause of ignition problems and it is also one of the easiest to fix. Your grill burner has small holes along its length that gas flows through. Over time these holes get blocked by grease, food bits and general buildup. Spiders are also a surprisingly common cause especially in grills that sit unused for a few months. They love building nests inside burner tubes.

Make sure the grill is completely off and has cooled down. Then remove the burner if you can and take a close look at those small ports. A wire brush or a straightened paper clip can clear out the blockage very easily. This one step fixes a huge number of ignition issues especially on grills that have not been deep cleaned in a while.

Check the Position of the Igniter Electrode

There is a small metal tip near the burner called the electrode. This is what creates the spark that lights the gas. For it to work properly it needs to sit very close to the burner usually within about an eighth of an inch. Over time it can move out of position build up grease or start to corrode.

If you can see the electrode take a look at where it is sitting and whether it looks dirty or damaged. A little cleaning can sometimes fix the problem right away.

Could Weather or Humidity Be the Cause

This one catches a lot of people off guard. Humidity and moisture can affect ignition systems especially battery powered ones. If your grill was working perfectly before a rainy stretch and now suddenly will not light give it some time to dry out. Also check the battery compartment for any moisture. Sometimes that is genuinely all it takes.

Signs It Is a Bigger Problem

If you have checked the gas replaced the batteries cleaned the burner ports and it still will not light then something more serious is probably going on. Here are the signs that it is time to call a professional:

• You have tried everything above and nothing has worked
• The electrode looks visibly corroded or broken
• Multiple burners are not working at the same time
• You can smell gas that does not go away

Repair or Replace? How to Decide When an Appliance Breaks Down

A Word on Gas Safety

If you smell gas that does not go away, turn off the gas supply at the source right away. Do not try to light the grill and do not keep troubleshooting. A persistent gas smell means something needs to be inspected by a professional before the grill is used again. This is not a situation to work around.
