The evaporator fan blade circulates cold air from the evaporator coil throughout the refrigerator and freezer compartments. When it cracks, chips, or becomes unbalanced, airflow drops — the fridge runs warm, the freezer struggles to hold temperature, and the compressor works overtime trying to compensate. The XPart 660XP Fan Blade is a premium aftermarket replacement for the Supco FB660, engineered to the same 6-5/8" diameter and 25D pitch for a direct drop-in fit.
✓ Symptoms This Fixes
- Refrigerator not cooling properly despite compressor running
- Freezer temperature rising or inconsistent
- Loud rattling, vibrating, or thumping noise from inside the fridge
- Fan motor running but airflow noticeably reduced
- Visible crack, chip, or missing section on the fan blade
- Frost buildup on evaporator coil from poor air circulation
- Compressor running continuously without reaching set temperature

Pro Tip — Inspect the Fan Motor While the Blade Is Off:
A cracked or unbalanced fan blade puts extra load on the fan motor shaft and bearings over time. While the blade is removed, spin the motor shaft by hand — it should turn smoothly with no grinding or resistance. If the shaft feels rough or the motor hums without spinning, replace the motor at the same time. Doing both in one visit prevents a callback when the stressed motor fails shortly after the blade replacement.

✓ Installation Notes
- Skill Level: Beginner-friendly — basic hand tools only
- Estimated Time: 15–30 minutes
- Key Steps: Unplug refrigerator → Remove freezer contents and shelving to access evaporator panel → Remove panel screws and lift panel to expose fan assembly → Note blade orientation (direction of pitch) before removing → Pull old blade off motor shaft (may require gentle rocking) → Press new blade onto shaft in same orientation until fully seated → Confirm blade spins freely without contacting shroud → Reassemble panel and restore power → Listen for smooth, quiet fan operation
- Safety: Always unplug the refrigerator before beginning. Confirm the blade pitch direction matches the original — reversed pitch will push air the wrong direction and worsen cooling.

✓ Frequently Asked Questions
How do I know if the fan blade is the problem and not the fan motor?
If you can hear the fan motor running (a hum or whir) but airflow inside the fridge is weak or absent, the blade is likely cracked, missing a section, or has slipped on the shaft. If the motor is completely silent when the fridge is running and the door switch is held closed, the motor itself has failed. Inspect the blade visually first — a cracked blade is usually visible without removing the evaporator panel.
Is the 660XP a direct replacement for the Supco FB660?
Yes — the XPart 660XP is engineered to the same 6-5/8" diameter and 25D pitch as the Supco FB660 and is a direct drop-in replacement. It is a premium aftermarket part and is not affiliated with or endorsed by Supco or any OEM manufacturer.
Does blade pitch direction matter?
Yes — pitch direction determines which way air is pushed. Installing the blade in the wrong orientation reverses airflow and will make cooling worse, not better. Always note the direction of the original blade before removing it, or photograph it from the front before pulling it off the shaft.
