Abstract
An air handler enclosure having a pivotal door panel covers an access opening leading to a blower inside the enclosure. The door panel is held in engagement with the enclosure when the panel is fully open or closed. The panel can completely disengage the enclosure if the panel is first pivoted to an intermediate position between the fully open and fully closed positions. However, the weight of the panel itself urges the panel to remain engaged with the enclosure as the panel pivots through the intermediate position, which helps prevent the panel from disengaging the enclosure unintentionally.
