# Wolf burner will not simmer

### The fastest diagnosis is the code

Check the cap seating and the port ring first, exactly as for a burner that will not light. A partially blocked ring loses the low end long before it affects the high end, which is why simmer goes first.

### Why this is a page rather than a footnote

People buy this equipment for the low end as much as the high end. A burner that will not hold a low flame is not a minor complaint on a professional range — it is the feature that was paid for, and it is usually fixable in an ordinary service visit.

### The low end fails first

That is the useful principle here. Ports partially blocked, pressure slightly low, orifices slightly wrong — none of them show at full output and all of them show at simmer. So a simmer complaint is often the earliest possible warning of something worth catching.

Partially blocked ports

The low flame needs every port to carry its share. Blocking that is invisible at full output kills a simmer.

The valve adjustment

Each burner valve has a low-flame setting. It is adjustable, it drifts, and it is set with a flame in front of you rather than by numbers.

Wrong orifices after a fuel conversion

A range set up for the wrong gas is closest to correct at full output and worst at simmer, which is why this is the symptom that finds it.

Gas pressure at the appliance

Low pressure loses the low end first. It is the house rather than the range, and it is measurable.

A cap seated wrong

Same first suspect as everything else on a burner, and same free fix.

Look at the ring at the lowest setting

Even and continuous, or broken and patchy. Patchy is ports.

Try every burner

One burner is that burner. All of them is pressure or a conversion.

Flame color at full

Yellow anywhere points at a conversion or a mixture problem, which explains the simmer too.

When it changed

After a clean, after a move, after a gas supply change. Each points somewhere different.

Low flame is a real specification

What it usually means

Flame goes out at the lowest setting

Nothing between "off" and "too hot"

A simmer that used to work and does not
