The electric fan is one of the most useful household appliances, and it can provide the ventilation your house needs without taking up so much electricity as will come back to haunt you once the bills come in. Unlike heaters, blowers, and Honeywell radiators, the fan is a low maintenance device that can cool you down with just a switch of a button. Like all household appliances, however, a fan will sometimes break down and malfunction. Before thinking of purchasing a new oscillating fan, here are ways to repair the fan yourself.
Prepare the tools. Be sure to prepare all of the tools that you will need for a repair. You will need basic tools such as screwdrivers, small washers, electrical tape, and a multimeter. These are readily available in most leading hardware shops and supply depots. For special fans like the tower fan and the portable fan, you may need replacement parts and specialized gear that is available from the manufacturer. Most fans, however, only encounter minor problems that usually will not require brand new replacement parts.
Check the fan. Begin the repair by checking the fan and identifying the problem. The usual problem areas for the fan are the blades, the oscillator, and the speed control switch. Inspect for any cracks in the areas, dirt and debris which might have gotten caught around the sensitive panels and switch boards, as well as disconnected wires and signs of overheating such as discoloration and softened edges which could indicate that a part has overheated and has become very soft while the fan was in use.
Cleaning. In most instances, the fan can be repaired by simple cleaning. The contact board for the switch control will stop working once a layer of dirt and dust prevents the metal contact points from touching each other and sending electrical impulses that will power the fan. The actual fan blade rotators will sometimes stop because of the friction generated by fallen debris such as stray strands of hair. Keep in mind that the back of the fan functions to draw in air, which means that plenty of dirt accumulates in the fan. Use a soft towel or cloth to remove the dirt.
Tightening. If you hear rumbling when the fan is in use, remove the plug from the outlet and remove the grille. Afterwards, use a screwdriver to detach the nut and the spinner. This will allow you to pull out the blades. Clean the shaft and the motor housing, and then return the blades. Tighten the hubs and the bolts to prevent the blades from generating vibrations. Most rumbling noises are the result of wobbly fan blades.
Replacement. If the fan has parts that have broken down, remove these carefully. Make sure to detach the wiring one by one, especially if the broken part is in the motor. Purchase new replacement parts and use these. Make sure to align the gears and to tighten the screws before assembling the fan again.
Repairing an electric fan is relatively easy. The next time your electric fan-K or fan heater starts to wobble, make noise, or stop working altogether, you will know what to do. Keep safe during all repairs and make sure that you do not work with fans that are connected to the power supply.
