GE Spacemaker 1800 vent door problem

When I turn the micro wave on the vent door tries to open but the motor is making a loud noise. When the oven stops the door tries to close and the motor makes a loud noise. Sometimes the noise will stop on its own and sometimes I have to unplug the oven to make the motor stop. Sometimes the vent door will open and close and sometimes I have to help it. The vent fan works ok just the door has problems, can I fix this problem myself? If so, how.
Thanks
Ron

Hi.

Most likely the problem is bad motor assembly
