Freezer Not Cooling or Frosting Over? Evaporator W11572047 – Fix Frost Buildup Fast

When your freezer stops cooling or ices over completely, the evaporator coil is the most common cause. In most Whirlpool and Maytag upright and chest freezers, a failed or blocked evaporator coil causes the freezer to lose cooling capacity, accumulate heavy frost on the back wall, or stop maintaining temperature entirely. ⚡ Common failure point in Whirlpool-built freezers. Part W11572047 is the genuine OEM replacement evaporator assembly that restores proper refrigerant heat exchange and returns your freezer to full cooling performance.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Your appliance is a Whirlpool or Maytag upright or chest freezer (not a refrigerator freezer compartment)
• ✔ The compressor runs but the freezer is not reaching or maintaining target temperature
• ✔ Power supply and door seals are confirmed OK — no obvious gasket failure
• ✔ The defrost heater and defrost thermostat have been ruled out or tested
• ✔ ONLY problem is loss of cooling, heavy frost accumulation, or icing over of the evaporator coil

🔧 Common Symptoms

• Freezer not cold enough — contents thawing or soft
• Heavy frost or ice buildup on the back wall or evaporator cover
• Freezer runs constantly but never reaches set temperature
• Loud fan noise as airflow is blocked by ice accumulation
• Freezer cools intermittently — works after manual defrost but fails again quickly
• Visible ice block or frost wall behind the evaporator panel

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this evaporator restores normal freezer cooling immediately.

⚙️ Installation

Skill Level: MODERATE — 45–90 minutes. Disconnect power and allow the freezer to fully defrost before beginning — do not use heat guns or sharp tools to remove ice. Remove the interior evaporator cover panel (typically held by screws along the perimeter), disconnect the refrigerant lines and wiring harness from the evaporator assembly, and install the new unit in reverse order. Ensure all connections are secure and the drain tube is clear before restoring power. Allow 24 hours for the freezer to reach operating temperature before loading.
