Kitchenaid Refrigerator KTRA19KRSS00 Leaking

The Defrost Bimetal is an OEM part for Whirlpool refrigerators. It acts as a safety thermostat that monitors and controls the temperature during the defrost cycle. This component ensures that the defrost heater turns off when the evaporator coil reaches a specific temperature, preventing overheating and potential damage.

Causes of failure may include a malfunction due to wear and tear over time, electrical failure, or damage from moisture and ice.  

Symptoms of a bad Defrost Bimetal include:

• The refrigerator is constantly running without cycling off
• Frost buildup on the evaporator coils, leading to reduced cooling efficiency
• The refrigerator or freezer compartment is too warm
• Unusual fluctuations in refrigerator temperature

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

This evaporator tray collects defrost/condensate water and holds it where warm air can evaporate it, helping prevent leaks and odors. Replace a cracked or warped tray to restore proper drainage and protect surrounding floors and cabinetry.

• Collects water from the evaporator/defrost system and contains it safely
• Promotes evaporation using airflow and heat near the condenser area
• Helps prevent puddles beneath the appliance and mildew odors
• Common signs of failure: water on the floor, recurring leaks after defrost, visible cracks/warping, or standing water in the pan

• Disconnect power and allow components to cool before servicing
• Access the tray from the base or rear (panel removal varies by model)
• Transfer any brackets, clips, or grommets from the old tray as needed
• Ensure the drain tube seats fully into the tray and that the tray is level; restore power and check for leaks
