    This video shows you how to locate and replace the fuse inside a fan. In some fans, the fuse is hidden inside one of the short fiberglass sleeves (gold color bundle in the picture) that cover the connections between the motor windings and the control wires. There is only one fuse but you will need to move cut the string and gently slide each sleeve until you find the small (grain of rice size) fuse. . What follows is informative feedback from a viewer with precise terminology for the circuit elements of interest.

    Actually, clarification. The black square component you refer to at the start is not quite a fuse, as it wont trip off from over current. There really exists no fuse component in AC powered devices, but instead, are circuit breaker switches. Fuses are more common in DC devices. Not all devices, but some will have breakers, or also known as OVP switches (over voltage protection).

    How can u tell if thermal switch??? From the way its placed. If you notice see how its tied against the coil directly?? Thats for a reason. Its a thermal safety relay/switch. It gets tripped off when the coil gets extreme hot, to prevent the coil catching on fire.. And usually the thermal switch has been set off, breaking the circuit and coils get no power. Direct contact, and heat transfers inductively. Now it has to be replaced with same rated replacement. Brand makes no differenc3. Just rating. And then fan bearings both front and rear bearings need lube, and if excess dust, cleaning. Which usually is why heated up firstly. Dust and worn dry bearings bottleneck the coils.

    Once again to clarify its a thermal switch, not a fuse, or as i mentioned circuit breaker, which usually can be found on outdoor use AC current powered devices, such as air compressors, heat lamps, higher wattage lighting systems. So little black square component is an thermal switch. Usually rated around 115-120°f on 110-115v AC. Its the same in sense of an OVP Circuit breaker switch, where if the current exceeds the max rating allowed, it will trip it to the off position. In this case, if the coils on the stater gets too hot, or reaches max allowed.
