# Bosch HBL8454UC

### What a HBL8454UC is

A 30-inch single wall oven, upper series. It belongs to the 800 Series, which is where its parts and its features come from.

### What we are called out for on it

- [Oven not heating](https://boschmiami.support/symptoms/oven-not-heating/)
- [Oven door locked shut](https://boschmiami.support/symptoms/oven-door-locked/)
- [Oven controls not responding](https://boschmiami.support/symptoms/oven-control-panel-not-responding/)

### The thing worth knowing about this one

A single 30-inch oven under a counter is the easiest wall oven on this site to get out — which matters, because getting it out is most of the labor on any repair behind the cavity.

### Where the model number is

On the door edge of a dishwasher, visible when the door is open. On the inner frame of a refrigerator, usually behind a drawer. On the door collar or behind the filter flap on laundry. A photograph of the plate is enough — it tells us the series, the configuration and which parts fit, before anyone drives anywhere.
