	It will increase. The heat that comes out of the radiator goes into the cold side, and the compressor runs harder because the cold side doesn't stay cold enough. It is simply wasteful. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Temperature of the inside of the refrigerator will rise . Why ? Heat transfer from the room, if it is warmer than the inside of the refrigerator, to the inside of the refrigerator will warm the inside of it . Compressor will continue running but it will not keep up with the heat from the room . Always remember ,heat travels from the higher temperature to the lower temperature . Tal

	hmmm yeah it will increase as the compressor will reject or dessipate more heat ... :)

	your question is very subjective. i find the answers quite right but to me, i would consider the room stays the same temp. the room is considered a thermal reservoir. Nothing in the reservoir changes with effect of the fridge. Even heat dissipated or cold air generated is minimal to change the temperature. but if the room is very small, picture putting the fridge in a box not too big, then the temp would increase.

	Yes, the temperature inside the refrigerator will increase gradually. Also due to this the compressor will remain ON for prolonged period which will lead to wear and tear or simply failure of compressor. __________________ mech_rulez
