# Wolf cooktop not heating

### The fastest diagnosis is the code

Establish whether it is one zone or all of them before you call. One zone is that zone's element or generator; all of them with a live panel is the supply or the main control, and those are different visits.

### The count is the diagnosis

Before anything else: how many zones work. One dead zone among four is a contained repair with the rest of the appliance proving itself healthy. Four dead zones with a live panel is a supply or a control question and has nothing to do with the cooking surface at all. Those are different parts, different prices and different visits.

### What the codes add

This maker publishes open-circuit conditions per individual connection — fourteen of them on some models — so a code frequently names the exact zone and the exact circuit. That is the part of a diagnosis that normally costs an hour.

An element or generator open

This maker publishes open-circuit conditions per connection, which is unusually specific — the code names which zone.

A relay or triac not switching

The element is sound and nothing is feeding it.

One leg of the supply lost

A cooktop draws across two legs. Losing one leaves a lit panel and half or none of the zones working.

The main control

Every zone dead with a live panel, and no single element to blame.

On induction, a generator that has failed

The power stage under that zone rather than the glass or the control.

Count the zones

How many work, and which. Write it down before you call — it decides what we bring.

Breaker fully off and fully on

A double-pole breaker can drop one leg and still look set.

On induction, try a known pan

A zone that does not heat may simply not be able to see what is on it.

Photograph the code

The open-circuit conditions here name the connection, which is a diagnosis for free.

One zone or all of them

What it usually means

One zone cold, the rest working

Every zone dead with the panel alive
