Kitchenaid Refrigerator KTRS21KLSS01 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.

The Defrost Heater is an OEM replacement part for Whirlpool French door refrigerators. It is an electric heating element strategically placed within the refrigerator compartment and freezer liners. This component aids in preventing excessive moisture buildup from condensation formed during normal operation. 

Causes for heater failure include standard component degradation from prolonged use. Exposure to moisture accumulating over time can damage wiring insulation or short-circuit coil filaments as well.

Symptoms of an inadequate defrost heater involve:

• Frost buildup interfering with door seals and interior shelving
• Promotion of mold/mildew growth from sustained dampness
• Food spoilage risks due to the inability to regulate proper humidity 

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