Haier Refrigerator defrost drain clogged

If your Haier is leaving water in the bottom of the fridge or you find ice plugging the drain, you likely have a defrost drain clogged problem. The most common causes, in order, are a failing evaporator fan motor that lets cold air push ice into the drain, a clogged or frozen defrost drain or tube that needs flushing, and a missing or mispositioned drain strap that should conduct heat into the drain. Less common causes include a defective drain heater that fails to keep the drain clear and, only after you’ve checked the defrost parts, a bad main control board that stops the defrost cycle. You can quickly check the fan by turning the blade by hand, clear a frozen drain with warm water from a turkey baster, and inspect the drain strap and heater for proper placement. Test the defrost components before replacing the control board. Enter your model number on RepairClinic.com to find the exact replacement parts—evaporator fan motors, drain straps, heaters, and control boards—that fit your refrigerator.

01 - Haier Refrigerator Fan Motor

If the refrigerator's defrost drain is clogged, it's possible the evaporator fan motor is not working. If the evaporator fan is not running, cold air from the evaporator can migrate to the defrost drain causing ice buildup in the drain. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.

02 - Clogged or Freezing Defrost Drain

The defrost drain might be clogged or frozen. If the defrost drain is frozen, the water will overflow the drain trough and drip down to the bottom of the compartment. You can use a turkey baster and warm water to help clear out a frozen defrost drain and tube. You should also make sure the drain tube trap is clear by the drain pan.

03 - Haier Refrigerator Drain Strap

Some defrost drains are outfitted with a drain strap. The drain strap is a small piece of copper or aluminum that attaches to the defrost heater and extends partway into the defrost drain. When the defrost heater turns on, heat is conducted through the drain strap to melt away any ice that may have accumulated further down in the defrost drain. If the drain strap is not in place, the defrost drain may be more likely to freeze over.

04 - Haier Refrigerator Evaporator Fan Motor

If the refrigerator's defrost drain is clogged, it's possible the evaporator fan motor is not working. If the evaporator fan is not running, cold air from the evaporator can migrate to the defrost drain causing ice buildup in the drain. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.

05 - Haier Refrigerator Drain Heater

Some refrigerators are equipped with drain heaters. Drain heaters prevent the water in the drain pan from re-freezing and clogging the defrost drain. If your drain heater is defective or is not in the proper position, the defrost drain might freeze over.

06 - Haier Refrigerator Main Control Board

The main control board regulates the power supply to all of the refrigerator components, including the defrost system. If the main control board is defective, it may stop sending voltage to the defrost system which can lead to the defrost drain becoming clogged with ice. Control boards are frequently misdiagnosed—before replacing the main control, first test all of the defrost system components. If none of the defrost system components are defective, consider replacing the control board.
