An oven that runs hot, runs cold, or bakes unevenly is frustrating, but on most Miele ovens it’s a fairly routine repair. Here’s what’s usually behind it.
Temperature Sensor Faults Are the Usual Culprit
A failed or drifting temperature sensor is the most common cause of inconsistent baking. The sensor feeds continuous data to the oven’s control electronics — when it drifts even slightly, the oven can run well off the set temperature without any obvious symptom besides inconsistent results.
How to Confirm It’s Not Just the Recipe
Place an independent oven thermometer inside and compare it to the set temperature over a full preheat cycle. A consistent gap points to a sensor issue rather than a one-off baking mishap.
Control Board Faults Are Less Common, But Possible
If the oven won’t heat at all rather than just running inaccurately, a control-board fault may be to blame, especially after a recent power surge or outage.
Getting It Fixed
