What could be a reason for a drying oven to not maintain the proper temperature?

The reason a drying oven may fail to maintain the proper temperature when the door does not seal properly is significant, as a proper seal is crucial for maintaining the desired temperature. If the door does not close completely, heat can escape, leading to a loss of temperature stability. This situation can cause variations in the internal environment of the oven because the constant influx of cooler air disrupts the heating cycle, preventing the oven from reaching or maintaining the set temperature.

While other issues, such as a faulty heating element, a broken thermostat, or insufficient power supply, can also impact temperature regulation, the sealing of the door is a direct and immediate factor affecting heat retention. Properly functioning sealing mechanisms ensure that the designed thermal efficiency is achieved, which is essential for precise experiments or procedures requiring specific temperature conditions.
