A cooled display case includes a plurality of walls enclosing a compartment for displaying merchandise. A door is fitted within a door opening of the cooling compartment and swings from a closed position to a first open position and a second open position. A door closer yieldably urges the door to the closed position whenever the door is in a position other than the second open position. The door closer yieldably holds the door against swinging movement whenever the door is in the second open position. The door closer includes a guide arm which rolls within a guide track mounted on the door, and a track stop is detachably mounted to the track to block movement of the guide member in the track to prevent the door from moving to its second open position. The method involves selectively removing the stop pin so that the door is free to move to its second open position.
