# Wolf induction range error code E20

### What this one means

A temperature sensor is reading a value the control knows cannot be true, on an induction range, where the cooktop is a power electronics assembly and the oven below it is conventional. 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 sensor and its wiring back to the board
- The plug where that wiring passes through the cavity wall
- The board's own measuring circuit, which is what an implausible reading is checked against
- 0x27 = Heat sink sensor failure
- 0x36 = Temperature pin short cut
- 0x41 = Zone temperature value invalid

### Worth doing before you call

- Check whether the oven still heats with the cooktop off, and the other way round
- Note whether the oven heats at all, and whether it overshoots or never gets there

### Then what

An open sensor and a shorted one are opposite readings of the same circuit, and the appliance says which. That is the measurement a technician would otherwise start by taking.

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