What it looks like from the kitchen

## The symptom this code usually arrives with

A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.

- Induction zone switches itself off
					A zone that stops mid-cook, or a cooktop that shuts down after a long session at high power. On induction that is nearly always the appliance protecting itself, and it costs nothing to confirm.

														One zone stops during cooking

														Everything shuts down together

														A letter-F code on the display

## About Thermador cooktop error code F4

### What this one means

The electronics have got too hot and every zone has stopped. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.

### What the code covers

A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:

- The same causes as F2, further along
- A fan under the cooktop that has stopped

### What to try yourself

- Let it cool completely, then run one zone alone and watch whether it holds

### Then what

All zones rather than one points at the shared cooling rather than at any single zone.

This code is published for cooktops & rangetops and professional ranges. The [full list of codes](https://thermadormiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.

This article is based on:
