THINGS TO TRY

PREVENTION SUGGESTIONS
To try to prevent this problem, use the following precautions:
DO NOT EVER PUT YOUR CONSOLE IN THE FREEZER OR OUT IN COLD WEATHER
Some people think that doing this might help "fix" a hot console, in fact doing so could cause even bigger problems. Electronic devices like your console are made to function at and around room temperature, extreme cold temperatures can often cause just as many problems as extreme warm temperatures (such as overheating). Also if the console is located in a dramatically cold area while running, the difference in temperature between the hot console and cold air can create condensation which in turn will short out your console making the situation far worse. Condensation will happen more quickly if your console is hot due to the greater difference in temperature. DO NOT DO IT.
If none of the above suggestions work, contact MS customer support get get a support ticket started.
