On the unit plug, you'll notice a reset button. First, unplug the unit for about 30 seconds and then plug it back in. Then, press the "reset" button. There should be some resistance when you press it in to engage it, but if there's none, that's a more serious issue.

If the air filter is clogged, air cannot flow properly through the air conditioner. This greatly reduces the cooling capacity of the air conditioner. In addition, if the air filter is clogged, the evaporator coils will frost over. To remove debris from the air filter, try cleaning the filter.
