This precooler sleeve is the replacement tube that guides and protects the refrigerator precooler assembly, helping maintain proper airflow and component alignment for reliable cooling performance. What it does:

• Channels refrigerant/airflow around the precooler area to support efficient heat exchange
• Protects the precooler assembly from rubbing, kinking, or contact with adjacent components
• Helps prevent airflow leaks that can cause uneven cooling or frost buildup
• Commonly replaced when cracked, split, punctured, or otherwise damaged

• One precooler sleeve/tube

• Disconnect power to the appliance before beginning any repair
• Access may require removing interior panels or the evaporator cover; handle evaporator fins and tubing carefully
• Inspect adjoining seals and clips; replace any damaged fasteners to ensure proper fit

The Alumilastic Cement is an OEM part for Whirlpool appliances, typically used in refrigerators and freezers. It serves as a thermal mastic compound, designed to provide a secure and heat-conductive bond between various components, such as evaporator coils and the interior walls of the appliance. 

Causes of a bad alumilastic cement can include drying out, cracking, or losing its adhesive properties over time. This can occur due to age, exposure to temperature fluctuations, or improper application. When the cement fails, it can lead to poor thermal conductivity and decreased cooling efficiency.

Symptoms of a bad alumilastic cement include:

• Reduced cooling performance
• Unusual noises from the cooling system
• Components becoming loose or detaching
• Increased energy consumption

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