Eventually, the evaporator coils in your freezer will freeze over. This will cause the temperature in your freezer to rise so that it doesn’t work as effectively.

The fan shouldn’t run while the door is open, and most fridges or freezers go into a brief defrost mode every 8 hours or so. Otherwise, the fan should run most of the time.

It depends on what’s causing the problem. For instance, if there’s ice built up on the fan blades and preventing them from turning, you may just need to let the ice melt off. If the fan blades are damaged or the motor has stopped working, you may need to replace the fan or motor altogether.

You won't if the door is open. You'll need to close the door switch with a finger or place a strong piece of tape over it and wait for about one minute. The fan *should* come on. If it doesn't, take a look at "Test-an-Evaporator-Fan-Motor" within this site.
