This manufacturer-approved door torsion spring (part number WP4452396) is for microwaves. Door torsion spring WP4452396 applies tension to the door to keep the microwave door closed and to prevent it from opening too quickly. A service technician should install this door part because the door contains shielding components. The technician must correctly test the microwave for leaks in the microwave shield before you can safely use the microwave.
