Caframo Ecofans are known for giving years of worry-free performance, and that's one of the reasons they are so popular. Like anything with moving parts, however, they will eventually require maintenance. Fortunately, we have all ecofan parts like replacement motors with easy to follow "how-to" videos on each page so you can get your Ecofan running like the day you took it out of the box.
You should be able to insert the fan blade assembly back into the hole and then use an Allen wrench to tighten it back on. The hole for the Allen wrench is located on the side of the hub on the front of the fan blade assembly.
The manufacturer offers a 1 year warranty against defects in workmanship. If the fan should fail in that time frame, we can file a claim with the manufacturer for replacement parts or a replacement fan.
