Symptom
Viking simmer will not hold
A burner that will not stay lit on its lowest setting, or a "low" that is still hot enough to boil. On professional equipment the simmer is a specification rather than an afterthought, and a burner that has lost it can be brought back.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The valve out of adjustment
Gas valves have a low-flame setting and it drifts. It is an adjustment rather than a part, and it is what most of these turn out to be.

Ports partly blocked
At full power a blocked ring still looks fine. At simmer there is not enough flame left to bridge the gaps.
Open burner repair from $175 -
Flame sensing at low flame
The control loses sight of a small flame and closes the valve. That is the version that dies under a lid.

The burner head seated wrong
Off by a fraction, a burner will run at full power and refuse to simmer, which is a confusing way for it to present.
Open burner repair from $175 -
Gas pressure
Low supply pressure shows at the bottom of the range before it shows anywhere else, and it affects every burner rather than one.

01
One burner or all of them
All of them at once points at supply pressure. One points at that burner or its valve.
-
02
With a lid and without
Dropping out under a lid is flame sensing. Never going low at all is the valve.

03
Clean the ring first
Ten minutes on an open burner, and it is the free version of this repair.
-
04
Note whether it was ever good
A range that has never simmered properly since installation is a different conversation from one that has lost it.

Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About Viking simmer will not hold
The fastest diagnosis is the code
Try it with and without a lid. A burner that holds a simmer uncovered and drops out under a lid is a different condition from one that will not go low at all, and knowing which halves the diagnosis before anybody drives out.
Simmer is what this equipment was bought for
A professional burner is expected to go from a rolling boil to a genuine simmer without a diffuser, and losing that is losing a real part of the appliance. It is also one of the more satisfying repairs on the list, because it is usually an adjustment rather than a part.
Three conditions that look alike
A valve that will not go low, a ring too blocked to sustain a small flame, and a control that cannot see one — all three present as "it will not simmer". The lid test and the burner-by-burner test separate them in about five minutes.

Before you book
Questions about viking simmer will not hold
Is the simmer adjustable?
Yes. There is a low-flame adjustment on the valve and it is part of what setting up this equipment properly involves. A burner that has drifted can usually be brought back without a part.
It only goes out when I put a lid on.
That is flame sensing rather than the valve. The control has lost sight of a small flame under a covered pan and closed the gas. Specific, and fixable.
All four burners lost their simmer at once.
Then look at the supply rather than at the range. Pressure shows itself at the bottom of the range first, and a whole-top change points outside the appliance.
