Whirlpool Refrigerator WRS331FDDB02 Fridge too warm

The Defrost Thermostat is an OEM part for Whirlpool refrigerators. It is responsible for monitoring the temperature of the evaporator coils. When the coils reach a certain temperature, the thermostat signals the defrost heater to turn on and melt any ice or frost buildup. This ensures proper airflow and prevents excessive ice formation.

Causes of a bad defrost thermostat can be attributed to normal wear and tear over time or electrical malfunctions.  

Symptoms of a bad defrost thermostat include:

• Excessive ice buildup in the freezer section.
• Inadequate cooling in the refrigerator compartment.
• Frost or ice accumulating on the evaporator coils.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

The Door Upper Closure Cam is an OEM part for Whirlpool refrigerators. It is designed to provide proper closure and alignment for the refrigerator door.

The Evaporator Fan Motor Blade is an OEM part for Whirlpool refrigerators. It is a crucial component of the refrigerator's cooling system, attached to the evaporator fan motor to circulate air over the evaporator coils. This circulation helps distribute cold air throughout the refrigerator and freezer compartments, ensuring consistent temperatures and efficient operation.

Symptoms of a bad Evaporator Fan Motor Blade include:

• Unusual noise coming from the fan area, indicating the blade may be hitting another component or is unbalanced,
• Insufficient cooling in the refrigerator or freezer compartments,
• The refrigerator running longer than usual to maintain the desired temperature.

Causes of evaporator fan motor blade failure typically include physical damage from interference with other components, wear from continuous use, or buildup of ice or debris that unbalances the blade.

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

The Air Diffuser Assembly is an OEM part for Whirlpool refrigerators. It regulates the airflow between the refrigerator and freezer compartments, ensuring the proper distribution of cold air to maintain the desired temperatures in both sections.  

Common causes of a faulty air diffuser assembly include wear and tear from regular use, damage from ice buildup, or mechanical failure of the moving parts within the diffuser.

Symptoms of a bad air diffuser assembly include:

• Uneven temperatures between the refrigerator and freezer compartments
• Frost buildup in the freezer or refrigerator
• The refrigerator compartment being too warm or too cold
• Unusual noises coming from the air diffuser area
