The range of motion of the arm of a float which controls the energization of electrical heater elements disposed within a condensate receiving refrigerator pan will vaporize condensate therein from refrigerator cooling coils automatically to insure sufficient immersion of the heater elements to prevent overheating of the pan. The float actuates a magnetic reed switch which deenergizes the heater elements when the condensate surface level is reduced a small amount to open the contacts of the switch and thereby deenergize the heater.
