Neighbors in the cabinet
Tall wall-oven columns are popular in remodeled Bay Area kitchens: oven below, microwave above, perhaps a drawer underneath. Each unit gives off heat, and the cabinet must carry it away. When airflow is limited, every appliance in the column runs warmer.
The meaning of E23 is not confirmed; the installation setting is the common thread in what we hear. The oven control and its connectors tolerate heat only up to a point, so trapped warmth around them is worth ruling out.
What owners report
The upper oven of a double stays fine, but when both are used for a holiday meal, E23 appears on one of them. Or the oven shows the code after the microwave above has run hot for a long stretch. The cabinet face feels warm and the display looks dim. A code at a cold start would point away from trapped heat, so note when it shows up.
Where heat collects
- The gap between stacked units, where warm air rises.
- The space behind the oven if the cutout is tight or lined.
- The top of the column, where hot air gets trapped.
- Vent slots covered by trim added during the remodel.
What is checked first
The installation against the dimensions and clearances in the instructions for your model, the vent paths, the oven’s cooling fan on models that have one, then the control board and connectors for heat damage. A technician also asks how often the units run together. The cooling fan moves air around the controls, so a quiet fan matters even if the oven heats normally.
Safe outside checks
- Make sure nothing is stored on top of the column or against the vents.
- Avoid running two heat-heavy appliances in the column for hours at once if you can.
- Feel whether the cabinet face next to the oven is unusually hot and note the time.
Do not remove trim or fill gaps with insulation or foil. Both can make heat trapping worse.
Why a visit is the right route
Judging airflow and clearances means looking at the cabinet and measuring temperatures, which is best done on site. If the installation is at fault the finding is explained, and anything beyond the oven is a conversation with whoever built the cabinet. Any repair is quoted in writing first.
Information to gather
Photograph the column from the front with all doors closed, and note the model of each appliance in it if you can read the rating labels without moving anything. A photo of the cabinet top and the gap beside the column helps a technician judge the airflow before arriving.
Frequently asked questions
Not necessarily; the code is unconfirmed, and a perfectly built column can still run hot under heavy use.
If E23 follows double use, spreading out the cooking is a short-term workaround.
No. Ventilation changes should follow the installation instructions for your model.
Which appliances share the column, how long they run and where the heat is felt.
Model compatibility: Bertazzoni reuses codes across series and model years, so E23 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
