Fall Grill Tune-Up in DFW: 9 Things to Check Before You Fire It Up Again
Most DFW grills sit unused from July through September. Before the first cool evening, run this 9-point check: burner tubes, grease, gas hose, ignition, and vents.
It is the first evening all year that does not feel like standing in front of an oven. You walk out to the patio, lift the lid on the grill, and it smells like something crawled in there and gave up. The grates are orange. There is a paper wasp nest stuck inside the hood. You turn a knob, hit the igniter, and get one burner lit out of four.
This happens to almost every grill in North Texas, and it is not because you did anything wrong. DFW summers get hot enough that most people quit grilling around the Fourth of July and do not come back until the first cool front in late September. That is eight or ten weeks of a warm, dark, greasy box sitting outside doing nothing. Bugs love it. Rust loves it. Grease that was soft in June turns into varnish by September.
Here is the check we run on a grill that has been sitting. Most of it you can do yourself in about an hour. We will tell you exactly where to stop.
Why an idle grill is worse than a used one
A grill that gets used every week burns itself somewhat clean and never sits still long enough for anything to move in. A grill that sits does the opposite. Two things happen during a DFW summer layoff.
Insects move into the burner tubes. Spiders and mud daubers are drawn to the smell of the gas odorant, and the venturi tubes on a gas grill are exactly the right diameter for a nest. Grill manufacturers warn about this directly. As MHP explains in its own service guidance, a blocked venturi does not always stop the grill from lighting. It restricts gas flow to the burner, so gas backs up and ignites at the air shutter instead. That is a flashback, and it burns behind the control panel where you cannot see it.
Grease hardens. Drippings that were liquid in early summer bake into a hard, flammable layer on the flame tamers, the tray, and the bottom of the firebox. NFPA's grilling safety guidance comes down to three things: keep the grill clean, keep it clear of the house and anything that burns, and check the gas line. Two of those three are about what is sitting inside the grill right now.
The 9-point fall check
1. Look inside the burner tubes first
Before anything else, before you even turn on the gas. Pull the grates and flame tamers, then look up inside each burner tube where it slides onto the gas valve. You are looking for webbing, a mud tube, or a wad of debris. Clear it with a flexible brush or a bent wire, working from the shutter end out. If you find a nest, check every tube, not just the one that would not light.
2. Look at the burner ports
The little holes along the sides of the burner tube clog with carbon and rust. Run a stiff wire or an opened paper clip through the blocked ones. If a burner has holes rusted into each other so they form a slot, that burner is done. Replace it rather than fight it.
3. Pull the grease tray all the way out
Not just a look. Slide it out and see what is under it. Most built-in grills have a second layer of grease on the floor of the firebox that the tray never catches. Scrape it into a bag. Do not hose it into the island cabinet.
4. Inspect the hose and regulator
Bend the hose gently along its length and look for cracks, chalky spots, or hardening. Texas sun ages rubber fast. Any crack means replace the hose, not tape it. On a natural gas grill, check where the flex connector passes through the island wall for kinks or rub marks.
5. Leak-test the connections
Mix dish soap and water half and half, brush it on every fitting, then turn the gas on with the burners off. Growing bubbles mean a leak. Shut the gas off at the tank or the valve and stop there. Do not light it.
6. Check the ignition
Most spark modules run on a single AA or AAA battery that has been sitting in Texas heat for a year. Replace it before you decide the igniter is broken. Then look at the electrode tip; if it is coated in grease, it will not spark, and a wipe with rubbing alcohol often fixes it.
7. Deal with the grates
Surface rust on cast iron cleans off with a wire brush and re-seasons with a thin coat of high-smoke-point oil. Stainless grates that have gone dull are usually fine. Grates that flake apart when you brush them are not worth saving.
8. Clear the island vents
This one is for built-ins and it matters more than people think. Propane is heavier than air, so if it leaks inside an enclosed island it settles at the bottom instead of drifting away. That is why manufacturers require vents in the island walls. Wasps, leaves, and stray mulch block them. Get a flashlight and confirm every vent opening is clear on both sides.
9. Look inside the island cabinet
Open the access doors and look for droppings, nesting material, or chewed insulation. Rodents chew on flex line, and mice in an outdoor kitchen are common in DFW backyards. If you find evidence of chewing near any gas line, shut the gas off and get it looked at.
What about cold weather and propane?
You will read that cold weather kills propane pressure. It is true, but it is honest to say it is rarely your problem in Dallas-Fort Worth. Liquid propane vaporizes readily well below freezing; the pressure loss that actually stops appliances shows up at deep-cold temperatures far below a normal DFW winter night. On the handful of hard-freeze days we get, keeping the tank above about a third full is enough. If your grill runs weak on a 60-degree evening, the cause is inside the grill, not in the weather.
Do it yourself, or call?
| Situation | What to do |
|---|---|
| Dirty grates, greasy tray, dead igniter battery | Handle it yourself. Hour of work, no risk. |
| Webbing or a mud nest in one burner tube | Clear it yourself, then check every other tube. |
| Soap test shows bubbles at a fitting | Shut the gas off. Do not light it. Call. |
| Cracked or hardened gas hose | Replace before use. Call if it is a hard-plumbed built-in. |
| Smell of gas with everything turned off | Leave it off, get away from it, and call. |
| Rodent damage near a gas line | Shut off the gas at the valve and call. |
| Flames rolling out under the control panel | Shut it down. That is a flashback. Call. |
The pattern is simple. Cleaning is yours. Anything involving gas that is not behaving is ours.
What a professional deep clean actually covers
When we do a grill deep clean, the grill comes apart. Grates, flame tamers, and burners come out. Burner tubes get cleared and inspected. The firebox gets scraped down to metal. Ignition gets tested, the gas connections get leak-checked, and the island vents get verified on a built-in. Grill deep cleans start at $239, and everything we do carries a 1-year workmanship warranty.
If something is actually broken, we quote the repair after we see it. We do not price burner or valve work sight-unseen, because a clogged burner and a corroded one are two different jobs at two different prices, and quoting blind is how people end up surprised on the invoice.
Frequently asked questions
How often should a gas grill be deep cleaned?
Once a year is the baseline for a grill used a few times a month. Twice a year if you cook on it weekly or cook a lot of fatty meat. In DFW, the natural time for the annual clean is right now, at the end of the summer layoff, before heavy fall and holiday use.
Why does only one burner light on my grill?
Usually the crossover or carryover tubes between burners are clogged, or that burner's ports and venturi are blocked. It can also be a failing spark electrode on that one position. Check for blockage first; it is the most common cause by a wide margin and it costs nothing to look.
Is a spider web in a grill burner actually dangerous?
Yes, and it is the reason manufacturers publish a cleaning procedure for it. A blocked venturi restricts gas to the burner and pushes gas back out at the air shutter, where it can ignite as a flashback behind the control panel. Grills have burned this way. It takes five minutes to check.
Can I pressure wash my built-in grill?
No. Water driven into burner tubes, valve stems, and the ignition module causes rust and electrical failures that cost far more than the grease you removed. Scrape and wipe instead.
Do I need to clean the grill before a home inspection or sale?
A built-in grill and outdoor kitchen are part of the property, and inspectors do note gas leaks and damaged connections. If you are selling, it is worth having the grill and any other gas appliances checked. We handle that as part of a home sale inspection.
