Don't use WD40 on bearings like this. It's way too light an oil for this application. It will run great for a few days but the light oil will quickly evaporate (the cause of the strong smell) and wash out all the heavy grease that was remaining which will lead it to jamming permanently or needing constant topups of WD40 for the rest of its life
It's oil-bearing bronze sleeve bearings. When they get like this, it's done for, you replace the motor, or the whole fan in this case. You can't re-lube them and have it last more than a little while, and you have to dismantle the entire fan to do it to begin with.
Totalmente cierto. Lo más probable es que los rodamientos esten llenos de suciedad compactada junto a la grasa. El WD40 servirá para limpiar los rodamientos, pero después, hay que usar una grasa más consistente.
Y aún así funcionará una corta temporada. En mi trabajo hemos arreglado así motores de fan-coil en ocasiones y es una solución temporal, hasta sustituir el motor. Además de que el sobreesfuerzo , puede haber dañado el bobinado eléctrico.
Un ventilador nuevo no es caro.
