A humidity controlled food warmer includes a humidity control for adding moisture to a closed environment. A heater for the enclosure maintains the air temperature within a certain range, for example 1 DEG F., and in this condition the humidity control heating element operates at preselected intervals. When the cabinet is opened and the temperature sensor notes a deviation by another amount, for example 4 DEG F., the heating element of the humidity control is operated continuously until the temperature rises above the deviation temperature and for a preselected time thereafter. A controller measures the amount of time the deviation occurred and the time of humidity generation is related to such amount of time, such as a multiple thereof, but preferably an amount of time not to exceed another preset period of time.
