You can make deformation results of the first 2 modes, and play the animation to see how the rigid parts are moving away from the rest of the model.
The 3rd mode frequency is pretty small too. Check that too.
I noticed hinges on this model. If you have used frictionless contacts or revolute joints, it allows the door to swing open in rigid body motion. If this modal analysis is just a check for rigid body motion but you intend to use a static structural analysis, then consider frictional contacts in the hinge pivots if there is force against the hinges to cause friction or consider another means to hold the door.
