The following troubleshooting chart is a guide to more efficient composting using a turning unit.

SYMPTOMS	PROBLEM	SOLUTION
The compost has a bad odor.	Not enough air.	Turn it.
The center of the pile is dry.	Not enough water.	Moisten materials while turning the pile.
The compost is damp & warm in the middle, but nowhere else.	Too small.	Collect more material & mix the old ingredients into a new pile.
