# Wolf grill heating unevenly

### The fastest diagnosis is the code

Light every burner on high with the hood open and look along each one. A healthy burner carries an even line of blue flame from end to end; blocked ports show as gaps, and a burned-through tube shows as flame coming out where no port is.

### The easiest diagnosis on the site

Almost nothing else here can be diagnosed by looking. A grill can: light every burner, open the hood and look along the flame line. Gaps are blocked ports, flame in the wrong place is a burned-through tube, and an even blue line from end to end means the burners are fine and the problem is the gas or the heat plates.

Ports blocked along part of the burner

Grease, carbon and insects. The flame line has gaps in it and the grate above them stays cool.

A burner burned through

Flame escaping underneath instead of through the ports. Looks fine from above until you light it and look along it.

Flavorizer bars or heat plates gone

They spread the heat, and once corroded through the grill cooks in stripes.

Low gas pressure

A tripped regulator or a nearly empty tank lowers every burner at once rather than one of them.

The hood thermometer

The cheapest part on the grill and the reason a perfectly good one seems not to be.

Look at the flame line

Even blue from end to end, on every burner, hood open.

Under the grates

Heat plates or bars corroded through leave the grill cooking in stripes.

All burners or one

All of them together points at gas pressure. One of them points at that burner.

Check the thermometer against a probe

Before deciding the grill has lost heat at all.

A burner you can look at

What it usually means

One zone hot, the next cold

Lower heat across the whole grill

A thermometer that reads nothing like the cooking

The fastest diagnosis is the code

Light every burner on high with the hood open and look along each one. A healthy burner carries an even line of blue flame from end to end; blocked ports show as gaps, and a burned-through tube shows as flame coming out where no port is.
