If the fan compartment door of an appliance is left off, what happens to the motor's current?

When the fan compartment door of an appliance is left off, the motor experiences a change in airflow and cooling conditions. The fan's role is to circulate air and maintain optimal operating temperatures for the motor. With the door missing, the motor is more likely to operate in a less controlled environment, potentially leading to increased temperatures.

As the motor runs at higher temperatures, its resistance may change, often leading to an increase in the current draw from the electrical supply to compensate for the thermal changes. In many cases, motors are designed to maintain performance despite varying loads and conditions. However, if the motor overheats due to insufficient airflow because of the missing door, it may draw more current in an attempt to preserve its performance and keep functioning. Thus, the increased current can be attributed to the additional load placed on the motor as it struggles to operate effectively without the necessary cooling provided by the fan.

This situation illustrates the importance of proper assembly and maintenance of appliances, where components like fan compartment doors play a crucial role in ensuring that motors operate safely and efficiently.
