    It needs 10-15 minutes for the filling to set-should still be warm.

    Grandma always said let it set long enough to whip the cream, she did it by hand with a whisk, though.

    Dtstellwagen would be right, the temperature would rise compared to having no refrigerator at all. But if you have an existing refrigerator and then open the door, it would make it a little cooler in the room.

    To put it another way, if you had no refrigerator in the kitchen to start with, and you buy a new one and leave the door open and plug it in, nothing will happen, since the heat inside the refrigerator would get transferred to outside the fridge which would just go back inside again making the process neutral. However, the compressor motor would generate some heat as all motors do. So actually, bringing in a new refrigerator and opening the door and plugging it in would increase the heat in the kitchen a bit due to the compressor motor, but that's all.

    Now what happens if you close the door? The heat inside the fridge that gets transferred outside the fridge can't get back inside so the heat in the kitchen increases. So if closing the door increases the heat in the kitchen, then opening it decreases the heat in the kitchen - but not as much as unplugging the fridge altogether.

    So opening the door to an existing refrigerator will decrease the heat in the kitchen.

    The room temperature will go up. The reason is because in order to cool, the refrigerator has to use energy to create a temperature gradient. The coils on the back of the refigerator get hot, while the inside gets cold. If the refigerator is in an isolated room, and it has the door open, you will be using energy to cool one side of the refigerator and heat the other side. Since the heating is always more than the cooling (due to the 2nd law of thermodynamics) the temperature of the room will increase.

    It will raise the temperature. A fridge puts out equal heat energy from the coils on the back, plus the process of moving energy uses more energy running the compressor motor, that adds more heat.

    To put another way a fridge just moves heat energy from inside the fridge to outside the fridge, with the door open the process is neutral, it doesn't go away, it just gets moved. Except for the energy you are bringing into into the space to move the energy, that electrical energy is being moved from the generating facility to inside your space, that adds more heat.

    The compressor in the refrigerator will burn up from being over worked.

    There won't be enough of cool air to cool a room.

    Room temp goes up because your refrigerator compressor is now running full time. Time to google "If I only had a brain" to locate the closest yellow brick road.
