Bosch Oven: door not opening and fan running

Professional Repair Guide

What is this symptom?

Is your Bosch oven's door stuck shut while the fan keeps running? This can happen after cooking or even when the oven should be off. Common causes include a cooling fan continuing to operate, a malfunctioning door lock mechanism, or issues with the control board. Understanding these symptoms can help you troubleshoot effectively.

Urgency: Medium

Important Tips for Bosch Models

  • Bosch ovens are designed to run cooling fans after use and may keep the door locked until a safe temperature is reached; this is normal behavior. Persistent failure to unlock may be due to the door lock mechanism or control electronics. This can also be signaled by error codes in some models.

Possible Causes

Intentional post‑use cooling fan operation/oven still hot

How to Identify: Fan continues after use but oven is still warm; door lock may remain engaged until safe temperature reached

Part: Cooling fan/oven internal thermostat

Door lock mechanism failure

How to Identify: Door remains locked indefinitely even when oven is cool and fan still runs; no unlock sound when cycle ends

Part: Door lock motor and latch assembly

Control board not sending unlock signal

How to Identify: Electronic controls appear unresponsive; door refuses to unlock despite waiting and resets

Part: Oven control board / touchpad

Temperature sensor (thermistor) malfunction

How to Identify: Fan runs excessively long and door remains locked because control thinks oven is still hot

Part: Temperature sensor
