How do I find a drain line? I have an apartment size fridge from Haier.
Please tell us what your actual problem is as there is no drain line per se. Refrigerators remove defrosted water to a drain pan under the evaporator coil through a plastic tube. But, when the drain tube or hole becomes clogged, it leaks water into your refrigerator or freezer. Luckily, cleaning the drain pipe takes little time and tools. UPDATE Most Frequent Causes for Refrigerator not defrosting Cause 1 Defrost Control Board The defrost control board determines how often to run the defrost cycle. If the board fails, the refrigerator will not go into the defrost cycle. Before replacing the defrost control board, first test the defrost heater and defrost thermostat. If the defrost heater and defrost thermostat are working properly, the defrost control board is likely defective. Cause 2 Defrost Timer The defrost timer turns on the defrost heater several times throughout the day to melt any frost that may have accumulated on the evaporator coils. If the defrost timer is defective, it may not advance into the defrost cycle, or it may not send power to the defrost heater during the defrost cycle. To determine if the defrost timer is defective, slowly advance the dial into the defrost cycle. The compressor should turn off and the heater should turn on. If the timer does not send power to the defrost components or advance out of the defrost cycle within 30 minutes, this indicates that the defrost timer is not advancing. If the defrost timer is not advancing, replace it. Cause 3 Defrost Heater Assembly The defrost heater assembly turns on several times throughout the day to melt away any frost that may have accumulated on the evaporator coils. If the defrost heater assembly is defective, the defrost system will not work, and frost will continue to accumulate on the evaporator coils. To determine if the defrost heater is defective, use a multimeter to test it for continuity. If the defrost heater does not have continuity, replace it.
