## Description

Fluval FX4 Motor Unit

Review: Great Motor, Happy with Purchase - Excellent replacement. Super simple to remove old motor and install this new one. Be sure you are aware it does not come with a new impeller. I wasn’t expecting one with the motor, but could see how some may miss that detail. I’ve had it installed for about two days now and it works perfectly. Only hope that it will last as long as the original motor did.
Review: Works great! - Works great, fit perfect, and will buy again if it stops working... more like when it stops working again. Hahaha seems to be about every 5 years.

### ⭐⭐⭐⭐⭐ Glad it was replaceable
*by L***! on March 31, 2026*

Bought this replacement motor when my 1.5 year old motor died. I woke in the morning to my fish gulping at surface of tank. The filter hadn't been pumping all night. Repluged it, It would only spin-up for a second, then shut down, repeatedly. . (And no, it wasn't the computerized start-up bubble-release cycle). Was upset the original lasted less than 2 years, but I realized fine gravel substrate had blown into filter and found the impeller, from my mis-aligned wave maker, jamming the motor overnight. My fault I guess. Maybe it overheated?
