Low flame on propane grill

Post: # 26476Post electra225 »

My old barbecue grill is probably ten years old by now and has been used a LOT. The best grill I have ever had. It is a Walmart product an "Expert-something" brand grill. It has always worked well, is easy to clean, and gives great results. The last time I used it, it was hard to light. The center burner will hardly light at all. The left one seems to be the best, the right one somewhere in between. The side burner works normally. I have plenty of propane. I accessed this article and followed its recommendations with no change.

https://www.bing.com/search?q=low+flame ... 1&hsmssg=0

My next step is to take it all apart to see if I can see what ails it. Failing that, I need a new grill. We cook almost 100% outside when it gets over 105 to keep the heat out of the kitchen and make the AC work harder. Anybody have any suggestions as to what the fix might be?..... ;)

It is possible the burners are all rusty in the inside which blocks the gas from getting out the proper holes. Also the holes could be gunked up with grease and dirt, kind of like an old VM changer. :roll: ;) :)

Thanks, Bill. I hadn't thought of the burners being rusty. I wonder if I can buy new burners. ;)

I'd say there's a good chance that Bill is right. The only other things I can think of is that maybe the regulator is messed up or the hose is pinched. Can a rubber hose break down from the inside?

Yes, Danny, they can. Brake lines, with age, can collapse from the inside causing brake issues. They look good on the outside, no leaks, so its one of the things that is really hard to diagnose because no one ever thinks of it, they just think they are not leaking so all is well.

Greg, Mr. Google will probably be able to help with a new burner and if an exact match is not available there are universal burners available that I am sure will work.

The burners seem to be okay. I have this thing all apart. I have the gas valves out, the venturi's out of them, soaking in alcohol. I don't really see an issue. I need to figure out how to get the valves out of the pipe so I can check it. Then I need to take the hose off from the side burner to the main burners. The side burner lights easily and works well, so I have to eliminate the tank, pressure safety valves and the regulator as the issue, I would think. I'm going to do a good general grill cleaning, time for that anyways. I reckon time will tell..... ;)

I don't think this would apply to your problem, but it would only take a few seconds to do. It's likely that you've probably already done it though.

If the side burner works good than it makes sense that the tank, regulator, and side burners, burner and valve are ok. Does the grill have two hoses, one for the side burner and the main grille burners. If that is correct and everything you have checked so far with the main burners seems ok I would suspect the main burner hose.

Actually, Danny, I need to burp my gas grille often. Not sure why, but about every 5th use it just does not act right and after burping it is fine again.

The valve to the side burner is "T'd" and a flexible metal line goes from the side burner to the main burners. The rubber line with the regulator from the tank goes to one side of the side burner valve. I have one end of that flexible line disconnected where it goes to the main burners. I have the burners soaking in dish soap solution, which may be counter-indicated, but surely won't hurt anything. All the holes in the burners seem open. I have every part I can take off soaking in dish soap. I have a storage container that I use to soak the parts. It stays plenty warm sitting in the AZ sun. I need to get the flexible metal line off and check that. Another thought I had was that the gas regulator valve may be stuck like in Danny's link, but it opens enough to let the side burner work okay, but not enough gas for the three main burners. If the flexible metal line is clear, my suspicion will have to fall on the gas regulator. Or the safety valve in the tank. I can eliminate the tank as being an issue by connecting it to my turkey cooker. If that works okay, and I don't find anything else wrong, and if I try resetting the regulator two or three times, and if it still doesn't work right, then I need to try a new regulator. If that doesn't fix it, I need a new propane grill....... ;)

Ideas? Thank you both for your input. :D :D

And.....I need to clean the lid over the side burner. I just found out that I need to remove the side burner from the cabinet COMPLETELY because the rod it pivots on comes out from the INSIDE, which is against the body of the barbecue grill. What a dumb design that is. :evil: :evil: :evil: :roll: :roll: :lol:

I have no idea why the regulator gets a fart stuck once in a while but they do. Must be they are not as good as they once were. Believe it or not, I have my parents grille, it is the back up one. My mom and I went together and purchased it for my Dad for his birthday back in the late 60's. It was an expensive one, purchased it from Pro-Gas which was a propane distributor here in town. It is made of cast iron, very heavy and the only thing that has every been replaced in the burner. The original stainless steel one gave out after 30 years of use. They just do not make things like they once did.

As for your grille, Greg. Possible the flex metal gas line or the regulator. But with my Webber gas grille, about every 5 use I need to burp the regular.

Good luck, and happy grilling.

"Expert Grill" is the name of my old grill. I think that is a Walmart brand. You can use propane or charcoal or use it for a smoker. It was TOTL when we got it, but that was YEARS ago, maybe 2012 or so. I clean it when I get a grease fire, but that is only about once a year or so. I've never used the charcoal side, I use it for storing my grilling tools.

They do. Not that exact model, anymore, but the Expert Grill brand is Walmart's house brand for their "outdoor living" line. They no longer stock replacement parts such as burners and regulators in brick and mortar Walmart stores. You have to order those online.

I have cleaned stuff that hasn't been cleaned since the grill was new. This thing will either work like new or not at all..... ;)

I have this thing put back together. The jury is out on the "works like new" prospect. One burner still seems to light hard, with only a partial flame until it runs a minute, then it fills out. The other two burners seem to be burning a bit higher. The burners are stainless steel. I wonder if the one that is lazy still has some water in it. The plan is to fix supper on the grill tonight, so we'll see how that goes. This thing is getting pretty long in the tooth generally. If it needs burners, I'll just buy a new grill.

I am laughing. In my old age I have become my father. I accelerate slowly, I glide toward stops signs, and I share his view of grilling. His theory was that if you have a perfectly good kitchen in your house, why would anybody want to cook outdoors? OK, I sound like Scrooge....

Perhaps your father never lived in Arizona. Outdoor grilling saves heat from the kitchen, thereby lessening the burden on the home "refrigeration".

Chris, I also accelerate reasonably, decrease speed approaching a stop light like you talked about. Our 2003 Tahoe weighs 6200 pounds, has 191,000 miles, running its original brakes on all four wheels. It pulled a trailer from MO to AZ, over "The Rim" with lots of 6% grades, never hurt the brakes. I sold my old Pontiac that had 207,000, still running its original brakes. Being reasonable is not as expensive as being first..... ;) ;)

I have a story about "refrigeration" I probably have shared before, but I might be talked into sharing it again. One of my best stories.....

You talked me into it..... :( :( :D :D

When we moved to AZ, I got a job as service manager for a large Texaco station. It was a beautiful, clean, busy, well-equipped, 6-bay shop with monied clientele. Located in one of the hoity-toity addresses in all of Arizona, the only Texaco station still in existence at the time that only offered full-service gas pumps. They are still there and are still the only full-service gas station anyplace around here, although they are now a Sinclair station, but I digress....

My job was to speak with each client, find out what their needs were, then work with them to facilitate their repair. A nice elderly lady drove up to my work area in a late-1960's Oldsmobile 98 four door hardtop. She advised that she needed her refrigeration checked. Being the customer-oriented individual I can be, I went inside to my desk, pulled out the Yellow Pages, and found her the phone number for Spencer's Appliances "Where you have a friend in the business". I wrote their name and number neatly on a Post-it note and handed it to her. She gave me a strange look. I glanced at the guys in the shop who were rolling on the floor laughing at me. You see, in Arizona, air conditioning is called "refrigeration". If you use the term air conditioning, the locals will advise you that "Y'all ain't from around here, are you?". She wanted the air conditioning checked in her Oldsmobile. :oops: :oops: :lol:

This nice lady was one of my best customers at that shop. A couple years later, she drove up to my area and said her car was making a noise like a kitten crying. We put her car up on the drive-on lift and found a thoroughly aggravated little bitty black kitten who had a death grip on the right rear coil spring. We finally dug this little kitten out of the Oldsmobile. I took him home, we named him Tubby, and he lived 15 happy years in our cat herd... :D  

I also have a story about a whistle....... ;) ;) :lol: :lol:

I had to smile when I read that. It was a long time ago when I heard that an old man said, "I remember in the olden days when people used to use the restroom outside and cook on the inside." Not an exact quote but close enough. I grew up with no running water in the house, so I knew exactly where he was coming from.
