- “The cavity never reaches temperature”
- “Food browning on one side only”
- “An oven consistently thirty degrees out”
Symptom
Miele oven will not heat
Cold, or simply wrong. An oven that is out by a consistent amount and one that swings between are different problems, and only one of them is the sensor everybody blames.

Four ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The temperature sensor
Drifting rather than failing. A cheap part and the most common one.

An element
Weakened long before it goes open circuit, which is why a continuity test passes on a bad one.

The relay
Which produces an oven that works sometimes.

The convection fan
Makes the cavity uneven rather than cold — the version where one side browns.

How it shows up
What people describe when they call
Two shortcuts
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.
If the display is showing something
- F134 The temperature sensor is detecting that the oven compartment…
- F134 The oven cavity temperature sensor has registered a temperature…
- F13 The temperature in the oven is too high
- F20 The steam oven/combi-steam oven is not getting hot
- F55 The oven has switched itself off automatically during use

About Miele oven will not heat
The fastest diagnosis is the code
Put an oven thermometer on the middle shelf and watch it through a full preheat and twenty minutes beyond. Consistently low and steady is a different diagnosis from swinging, and knowing which halves the visit.
Cold, or simply wrong
They are different problems. An oven that never gets warm is an element, a relay or the supply. An oven that reaches a temperature and holds the wrong one is almost always the temperature sensor drifting, which is a cheap part. An oven that swings between too hot and too cool is a third thing again.
Measure before you decide
An oven thermometer on the middle shelf through a full preheat and twenty minutes past it tells us more than any description can. It is the single most useful thing you can do before booking.
