Abstract
A method for defrosting a household refrigeration appliance including a compressor and a defrost heater. After a controller indicates that it is time for a defrost cycle, the compressor is operated if the temperature of the appliance is greater than a set temperature. The compressor is stopped when a temperature of the appliance is equal to or less than the set temperature. After the step of stopping, the temperature of the appliance is raised while the defrost heater is inactivated. After the temperature is raised, the defrost heater is energized. The controller pauses for a drip time after deenergizing the defrost heater before allowing the compressor to run.
