Symptom
Bosch oven not heating
An oven that never warms up, or one that heats but sits well below the temperature it was set to. Those are different problems with different parts and quite different figures.

Five 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
Reads wrong and the oven heats to the wrong point. Has its own published code, and it is one of the cheaper repairs here.

Calibration
An oven cool by the same amount every time is often adjustable rather than broken. The cheapest outcome on this page and it is checked before anything is proposed.

A heating element
Bake or broil. Usually visible — a blister, a break, or a bright spot where it burned through.

A gas igniter that has weakened
On gas ovens they fail slowly: the oven lights later and later until it stops lighting. Predictable and a known part.

A relay on the control board
The board is what switches the elements. When a relay goes, the oven behaves as though the element has, and only measurement tells them apart.

Before you call anybody
None of it needs tools, and all of it makes the visit shorter.
-
01
Put an oven thermometer in it
At 350 and again at 450. An oven cool by the same amount at both is a calibration story; one that is fine at 450 and cool at 350 is not.
-
02
Look at the elements while it preheats
They should glow evenly. A blister, a break or a section that stays dark is your answer.
-
03
Cut power for five minutes
At the breaker. Photograph any code first, because it will be gone afterwards.
-
04
Check the clock and any mode
A timed bake that has ended, a sabbath mode, or a demo mode from the showroom floor will all leave an oven that refuses to heat.
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 there is no code at all
The data plate is inside the cabinet, upper left wall or behind the grille. All models

About Bosch oven not heating
The fastest diagnosis is the code
These ovens publish a code for the temperature sensor specifically, which is unusually precise. If you have one, photograph it before cutting power — several of these codes clear at the breaker and are then gone for good.
Never hot, or never hot enough
No heat at all points at an element, a relay, or on a gas oven the igniter. Heat, but wrong points at the sensor or at calibration. The second pair are far apart in price and only a measurement separates them, which is why a thermometer in the cavity is worth more than any description.
What the codes add here
These ovens are unusually specific: the temperature sensor has its own code, the touch panel has its own, and communication between the two boards has its own. Several clear with five minutes off at the breaker — and it is always worth trying, because a code that survives that is a code that means something.

Before you book
Questions about bosch oven not heating
It is exactly 25 degrees cool, every time.
That is the calibration conversation, and many of these ovens can be adjusted. It is the cheapest thing on this page and we check it first.
The oven works but the broiler does not.
Useful — that separates the two elements and their relays. Tell us which one when you book.
What is demo mode?
A showroom setting where the display works and nothing heats. It arrives with appliances bought from a floor model, and it is cleared with a specific sequence rather than a repair.
