Freezer Frosting Over or Not Cooling Evenly? Evaporator Cover 5304524899 — Fix Airflow Failures Fast
Excessive frost buildup and uneven freezer temperatures are almost always an airflow problem — not a compressor problem. In most Frigidaire and Electrolux refrigerators, this is caused by a cracked, warped, or missing evaporator cover and air duct assembly. When it fails, cold air from the evaporator coils can't circulate properly through the freezer compartment — causing frost to accumulate on the coils, food to freeze unevenly, and the compressor to run continuously trying to compensate. ⚡ Common failure point in Frigidaire-platform refrigerators. Part 5304524899 is the genuine OEM replacement evaporator cover and air duct assembly that restores proper cold-air distribution and eliminates runaway frost buildup.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Refrigerator powers on and compressor runs normally
- ✔ Freezer gets cold but temperatures are inconsistent or frost is excessive
- ✔ Defrost heater and thermostat confirmed OK (or not yet tested)
- ✔ ONLY problem is frost accumulation on coils or poor airflow through freezer

🔧 Common Symptoms
- Heavy frost or ice buildup on evaporator coils or freezer walls
- Freezer not maintaining consistent temperature — warm spots or cycling issues
- Refrigerator section too warm despite freezer running
- Loud fan noise as evaporator fan struggles against blocked airflow
- Visible cracks, broken clips, or warped plastic on existing evaporator cover
- Compressor running constantly without reaching set temperature
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this evaporator cover and air duct assembly restores normal operation immediately after a full defrost cycle.

- Type: Evaporator Cover and Air Duct Assembly
- Brands: Frigidaire, Electrolux, Gallery Series
- Condition: New Genuine OEM
- Ships From: Canada
If your evaporator cover failed due to frost damage, inspect the defrost heater assembly and defrost thermostat while the freezer is open — a failed defrost system is the root cause of most evaporator cover failures. Replacing the cover without addressing a defrost fault will result in repeat failure within weeks.
⚙️ Installation
Skill Level: Moderate — 45–75 minutes. Disconnect power and empty the freezer before servicing. Remove all freezer shelves and drawers to access the rear panel. Unscrew the existing evaporator cover, disconnect any wiring harness clips on the air duct, and swap the assembly. Allow a full defrost cycle to complete before restoring power to prevent immediate re-frosting.
✓ Compatible Models
Confirmed compatible with select Frigidaire and Electrolux refrigerator models. Contact us to verify your model number before ordering — evaporator cover fitment is model-specific and must be confirmed against your full model number on the door jamb sticker.
💡 Pro Tip
Before fitting the new cover, manually defrost the evaporator coils completely using a hair dryer or by leaving the freezer unplugged for 24 hours. Installing the new cover over partially-frosted coils traps moisture and accelerates re-frosting — a clean, dry coil surface is essential for the new assembly to seal and perform correctly.
