How does your compost smell?
An unpleasant smell and wet compost use the sponge test to check the moisture content (see the next post) it may have become anaerobic. A smell of ammonia it is likely that it still has a high nitrogen content and needs more Browns adding. Compost with a high moisture content that smells of mildew should be returned to the bin and turned frequently to provide an increased airflow. Would chip could be added to help increase the air spaces,
