Abstract: A dispenser for dispensing food products at an elevated temperature includes a housing for supporting and heating a container of food product located within the housing and a pump for moving the food product from the container to a location external to the housing. One or more actuators are operatively connected to the pump and are selectively configurable to operate the pump in a first momentary state for dispensing the food product while the actuator is actuated and a second timed state for dispensing the food product for a predetermined period of time. An interlock device is provided to disable the pump when the housing is opened.
