The room will warm up.

The fridge with the door left open will run pretty much continuously to try to cool the inside. Our fridge doesn't know the door is open, so it keeps running. The thermostat inside never senses that the inside has cooled, so it tells the compressor to stay on. The room will be cooled by the fridge, but remember that the compressor dumps heat out into the room all the while that it's running. And because the fridge is not 100% efficient, there will be more heat generated than there will be cooling. The result? The room will eventually warm up.

I would disagree partially with the above answer. 1) Efficiency is a term not really used for refrigerators. The term coefficient of performance is used because it can be and usually is greater than one (or greater than 100% in other words) and equals the heat removed from the inside of the fridge divided by the work input. 2) Now, if a perfect fridge was running on a Carnot cycle (no friction in the parts and other criteria) that gives the most cooling for the least amount of work, the room would still heat up as governed by the first law of thermodynamics. W=Heat from the condenser - heat from the evaporator or W+QL=QH. In this case all the terms are considered to be positive numbers. Clearly QH>QL which means the room is getting warmer.

Probably the easiest was to understand this is that work is going into the insulated room which means the overall energy and therefore temperature is going up.

Is it ok to leave the refrigerator open?

No, for two reasons. First, the fridge door has to be closed to keep the air temperature inside the fridge cool enough to keep the foods cold and safe. Second, leaving the fridge door open causes the refrigerator to run more, costing more energy and running up the electric or gas bill.

Can you ruin a refrigerator by opening and closing the door too often or leave door open to put away groceries?

No, you cannot ruin the refrigerator by opening and closing the door or by leaving the door open for a few minutes. Refrigerators do have a lifespan for the number of times the doors can be opened and closed before a hinge breaks or the seal is damaged, but this cycle can be in the millions - so it won't be affected with normal use. Each time you open and close the refrigerator, some cool air escapes and can mean that the compressor will have to run to get temperature back to where it should be. Leaving the door open for a few minutes does cool off the interior and things inside will begin to cool off as well. This will result in the refrigerator compressor having to run to get the temperature back down. A good refrigerator is designed to have the compressor go through these cycles many thousands of times. The only reason someone may be concerned with having the refrigerator work more would be the electric bill (it goes up, refrigerator compressors use a lot of power) or the refrigerator compressor has had problems previously.
