Symptom
Bertazzoni oven running hot, cold or uneven
An oven that heats perfectly to a temperature that is not the one you set, or that browns on one side and undercooks on the other. Almost always a measurement problem rather than a heating one — and on this make it is measured with a thermometer, because there is nothing to read.

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 cavity sensor drifting
It still reads; it reads wrong. The oven obeys it faithfully, which is exactly why nothing looks broken.

A door that has stopped sealing
Heat leaving along one edge produces the uneven browning people blame on elements. Common on heavy doors whose hinges have weakened.

A convection fan that has stopped
On convection the fan is half the cooking. An oven that is even on bake and uneven on convection has told you which part to look at.

An element working at reduced output
Not failed, just tired. The oven gets there eventually and never quite holds, which reads as an oven that has become slow rather than one that is broken.

An oven that is not level
It bakes to one side and nobody ever connects the two. Free to check with a spirit level on the middle shelf, and free to correct.

01
Measure it
An oven thermometer on the middle shelf, 350°F, twenty minutes. Everything after this is easier.
-
02
The paper test on the door
Close a strip of paper in the door at several points round the perimeter. Where it slides out easily, heat is leaving.
-
03
Bake against convection
If only convection is uneven, the fan is the suspect rather than the elements.
-
04
A spirit level on the middle shelf
Front to back and side to side. It takes a minute and explains a surprising number of these.

About Bertazzoni oven running hot, cold or uneven
The fastest diagnosis is what you can see
Put an oven thermometer on the middle shelf and run it at 350°F for twenty minutes. If it settles thirty degrees or more from the dial, that is the appliance rather than your recipes — and it is one of the least expensive repairs there is. Do this before you call: it is the single most useful number you can give us.
Why a thermometer is the whole first step
On a make that publishes codes, a drifting sensor announces itself. On this one it does not, so the measurement has to come from you or from us — and it is the same measurement either way. Twenty minutes at 350°F with a cheap oven thermometer converts "my baking has gone wrong" into a number, and a number is what a diagnosis is built on.
The order of suspicion
Sensor, door, fan, element, level. That order reflects both how often each is the answer and how much each costs to put right, and it is deliberately the reverse of where most people start. Nobody calls about an oven and suspects the hinges — and yet a heavy door that has dropped three millimeters is behind a real share of these.

Before you book
Questions about bertazzoni oven running hot, cold or uneven
Can it just be recalibrated?
Sometimes, and it is worth asking. Most of these ovens have an offset adjustment for exactly this, and if the sensor measures correctly and the oven is simply reading a consistent amount out, an offset is the right answer and it costs nothing. What an offset cannot fix is a sensor that is genuinely drifting — then the amount it is out by keeps changing.
My old oven never needed this.
Older ovens ran on a mechanical thermostat with a wide swing, and people cooked around it without noticing. A modern oven holds a much tighter band, which is better — and it means a sensor drifting by thirty degrees is obvious in a way it never used to be.
One shelf is always darker.
That is usually the door or the level rather than the elements. Both are free to check with a strip of paper and a spirit level, and between them they account for most uneven-browning complaints that turn out not to be the convection fan.
