Broil King Low Flame? Reset the Regulator and Fix the Real Cause
If your Broil King lights but the flames stay short, lazy, and orange no matter how high you crank the Linear-Flow valves, you're almost certainly looking at a tripped regulator (the "bypass") or a fuel-delivery problem in the Dual-Tube burners. The good news: this is one of the most fixable issues on the grill, and a Broil King is almost always worth saving. Here's how we tell a five-minute regulator reset from a real repair, and how we knock out both in one visit.
What you're seeing
All burners stuck low after a propane tank swap
This is the classic Broil King regulator trip. Opening the tank valve too fast with the burners on sends a pressure surge that the safety device in the regulator reads as a leak, so it clamps fuel down to a trickle. Every Dual-Tube burner ends up with the same weak, orange flame even at HIGH. It's the single most common Broil King low-flame call we get, and it usually has nothing to do with the grill itself.
One burner low, the others fine
When a single Dual-Tube burner runs short while its neighbors are strong, the regulator is doing its job and the problem is downstream — a clogged burner port, a venturi that's drifted off the Linear-Flow valve orifice, or a spider/insect nest in the burner tube. Broil King's Dual-Tube design means one of the two stainless tubes can choke while the other still flows, giving you a lopsided flame.
Orange or yellow flames and sooty grates
Healthy Broil King flames are blue with a small yellow tip. Lazy yellow flames that leave soot on the Flav-R-Wave and the cast-iron grids mean the air-to-gas mix is off — usually a partial port blockage or a shutter/venturi obstruction, not a regulator fault. Cooking on it like this wastes propane and bakes carbon onto everything.
Slow to heat, won't pass 400-450°F
If the grill lights normally but tops out far below its rated temp, you've got restricted fuel volume. A tripped regulator is the first suspect; a kinked or aging hose, or grease-caked Flav-R-Wave panels smothering the burners, are the next. A properly running Broil King should climb past 500°F with the lid down well inside 10-15 minutes.
Igniter clicks but flame is weak once lit
The rotary or electronic igniter only sparks the gas — it has nothing to do with flame size. If it lights but stays low, ignore the igniter and look at fuel delivery: regulator, valves, and burner ports. A weak flame with a working igniter is a fuel problem, full stop.
How we fix it
We start by ruling the regulator in or out, because a reset costs you nothing: with the lid open, we turn off all the Linear-Flow valves, shut and disconnect the tank, then reopen the tank valve slowly for a full count before relighting — that clears the bypass on most Broil Kings. If the flames come back strong, we're done with the regulator and we move straight into the deep-clean. If they don't, we pull the cast-iron grids and Flav-R-Wave panels and inspect the Dual-Tube burners directly: we check each burner port for grease and rust scale, confirm the venturi tubes are seated over the valve orifices, and look for spider nests in the tubes (a real culprit on grills that sit covered). From there we test the hose, the orifices, and the regulator itself for a true failure. We're honest about repair versus replace — Broil King uses heavy-gauge stainless Dual-Tube burners and Flav-R-Wave panels that hold up for years, so on most of these grills the fix is a reset, a port clean-out, or a single burner swap, not a new grill. We carry common Broil King burners and parts, and whatever the diagnosis, we deep-clean the burners, grids, and cookbox in the same visit so you get the grill back working and ready to cook.
Questions, answered
- How do I reset the regulator on my Broil King?
- Turn all the burner valves to OFF, then close the propane tank valve and disconnect the regulator from the tank. Wait about 30 seconds, reconnect, and open the tank valve slowly — count to five — before you turn on any burners and light the grill. Opening the tank slowly with the burners off is what keeps the safety bypass from tripping again. If full flame doesn't return after a couple of tries, the problem is past the regulator and worth a real look.
- Why is my Broil King burning low even after a regulator reset?
- If a reset doesn't fix it, the restriction is downstream of the regulator. On Broil Kings the usual suspects are partially blocked burner ports, venturi tubes that have slipped off the Linear-Flow valve orifices, a spider or insect nest inside a Dual-Tube burner, or a kinked/aging hose. Grease-caked Flav-R-Wave panels can also smother the flame. These are exactly the things we check and clear on a visit.
- Is it worth repairing a Broil King or should I replace it?
- Almost always worth repairing. Broil King builds with heavy stainless Dual-Tube burners and Flav-R-Wave panels that are made to be serviced, and parts are readily available. Unless the cookbox itself has rusted through, a low-flame issue is a reset, a port clean-out, or a single-part swap — far cheaper than a new grill of the same quality.
