What is a symptom of a malfunctioning door latch in an oven?

1. The oven produces excessive smoke

2. The oven does not heat up properly

3. The door does not open at all

4. The oven displays an error code

The correct answer is: The oven does not heat up properly

When considering the symptoms of a malfunctioning door latch in an oven, the issue primarily relates to how the oven operates in response to the door being either secured or improperly sealed. A door latch that is not functioning properly can lead to inadequate sealing, which in turn affects the oven's ability to maintain the correct internal temperature. If the door latch fails to engage fully, this can prevent the oven from heating properly, as most modern ovens have safety mechanisms that prevent operation if the door is not securely latched. Therefore, the symptom of the oven not heating up properly directly correlates with the malfunction of the door latch. Other symptoms, such as excessive smoke, unresponsive door movement, or error codes, might indicate different problems or combinations of issues within the oven's overall functionality but are less directly attributed to the door latch itself.
