How to Service A Table Fan

by:Chairlady     2020-06-21
This Hestar table fan problem has not been rotating despite the fact that it already switched 'On'. You could hear an audio coming through motor as soon as I try turning the propeller I ran across it to be stuck! By right a good fan however turn it, the propeller should rotate according for the force applied to it. May possibly be the long time of accumulation of dust who had jammed the motor shaft preventing it from turning smoothly. Once the spine cover and the lever have been removed, I could see lots of dust and dirt on the motor. We used a pressure together with a brush totally up after you. You might possibly see an electric motor starting capacitor attached next to the motor. Is actually the Metallized Polypropylene Film type of capacitor. Task of the motor start capacitor (AC motor capacitor) is give that electrical 'push' to obtain the motor rotation went on. Without a motor starting capacitor (such as when one open circuit or burns up), as soon as the voltage is applied, the motor will just sit and hum. But if you are to grab the shaft (or the propeller) while giving it a spin, the motor would (usually) start and run normally. I do not think the capacitor have problem because the symptom was the shaft jammed causing it never to rotate. Anyway I took out the capacitor and appearance it by using a digital capacitance meter observe if the capacitance is within range or not. The value was, and it also is slightly lower then the tolerance (the tolerance for this type of capacitor means 10%). In the event the capacitance value is lacking then Let me replace it with the most up-tp-date one. Please make sure you get yourself a replacement an issue same if not more voltage and when possible while using the same capacitance. You can easily get an auto starting capacitor from any electronic their distributors. I put back the capacitor and start servicing the fan. First I sprayed the Philip oil base on the contact that caused the shaft in order to find rotate. The shaft immediately rotates (turned by my hand) smoothly the moment it had oil in it. When I switch the fan 'On' again, the motor start to run! I off the fan again and applied some grease into the trunk gear that controls the fan whether you want it to be to be 'still' or 'rotate' (don't use the oil spray because it could maybe worn the gear faster). After everything was done, I tested the fan and it worked much like new cooling fan! Servicing the table fan isn't difficult and also can try servicing one inch your home. Remember, safety to help come first, make sure you unplug the AC cable before starting to dismantle the fan apart.
