What it means

On Siemens built-in ovens with electronic controls this code appears when the temperature inside the oven or around the electronics exceeds the safe limit, so the oven cuts heating automatically. Common causes are a cooling fan that does not run, blocked ventilation in the cabinet, a temperature sensor reading wrong, or a stuck relay keeping the heater on. Oven codes differ between series, so confirm the meaning in your oven manual; the same number can mean something else on other brands.

Models covered: Siemens built-in ovens with electronic controls; oven codes differ between series.

Symptoms4

Heating cuts out suddenly and E115 shows.
Unusual heat on the door handle or nearby drawers.
The fan does not run after switching off although the oven is hot.
A faint burning smell around the oven in some cases.

Possible causes5

A failed cooling fan, or one clogged with dust and grease.
Ventilation openings in the cabinet or under the oven blocked or too small.
A faulty temperature sensor reading higher or lower than the real value.
A stuck relay on the control board keeping the heater on.
Long use at very high temperature with a door that does not close well.

How to diagnose5

Switch the oven off, disconnect it at the breaker, and let it cool fully with the door closed.
Check that the ventilation openings in the cabinet and under the oven are open and clean.
Make sure the door seal is intact and the door closes properly.
A technician disconnects power before removing the oven, then tests the cooling fan and temperature sensor against the manufacturer specification.
The technician checks the board relays and the thermal cut-out, and never bypasses any thermal protection.

How to fix5

Provide the ventilation the installation guide requires around the oven.
Have the technician replace a damaged door seal.
Clean or replace the cooling fan.
Replace the temperature sensor or the control board if either is confirmed faulty.
Run the oven under supervision at a medium temperature to confirm stable heat and no returning code.

In Saudi riyals; the highlighted part is the expected range for this fault.

The cost is low for a ventilation or sensor problem, and higher when the cooling fan or control board must be replaced.

Prices are rough estimates including the part and the technician’s fee, and vary with brand, model and part source.

Frequently asked questions

Why does the oven fan normally keep running after switch-off?

It cools the electronics and the front after cooking. If you notice it no longer runs and E115 appears, the fan is one of the first things to check.

Is this code dangerous for the kitchen?

It can be, because overheating damages the cabinet and electronics. Disconnect the oven at the breaker and do not use it until checked, and never try to bypass any thermal protection.

Can self-cleaning trigger the code?

On ovens with pyrolytic self-cleaning the temperature gets very high, so weak ventilation, a weak fan or a worn door seal can trigger the code. The same checks apply.
