# Bosch range error code e302

### What this one means

The power board has overheated.

### 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 power board and whatever is preventing it cooling

### Worth doing before you call

- Let the appliance cool completely before anything else

### Then what

Note the case: a lower-case e302 is the power board and an upper-case E302 is the control panel. The manufacturer publishes them as two separate conditions with two separate answers, and it is the one place on this appliance where the capital letter changes the diagnosis.

This code is published for ranges and wall ovens. [The full list of codes](https://esbosch.djwp.xyz/error-codes/) has the rest.
