Electric Fan Needs Push Start

It is up to you to find that spot.

680 the fan online. The starting phase of an electric motor occurs for just a few seconds but it requires multiple times the circuit size to deliver this power and start the motor this is why special motor controls are required for larger motors and prevent the circuit from tripping off during the start cycle. If the blades do not move when you push them by hand and its a new fan packing material may be jamming it. Feel around the sides of the blade guards for clips that are holding the 2 parts together.

The torque isnproduced by the leading current which is provided by the capacitor. Most fans have a start capacitor that gives them the boost they need to start turning. Electric motor will not start but runs if started by hand.

Electric outdoor ac unit worked fine yesterday. If the fan doesnt start running you may have a bad fan motor. Unplug the fan and either unhook the blade guard or unscrew the pin.

Then push to start. If there are clips unhook them and remove the front half. If you have difficulty getting the blades to turn there may be debris wrapped around the fan axle or the motor bearings may be dirty or jammed.

A simple fix for your fan that doesnt start. If its an older fan that worked before a screw or part may have come loose and jammed it. Next i put the turntable back on with the belt in place switched on the power.

If the capacitor goes week it may not start by itself and will need to give it a slight spin to start. Wire a push button switch across it. Last night wife notice fan was not spinning only a weird hum.

A capacitor connected to a separate coil on the motor creates an alternating electric current ahead of the main phase by 90 degrees. Just for grins i push started the blade like in the video and it started up. Assuming its a single phase fan.

If the capacitor is not replaced when you notice it in due course the overall speed of the fan will reduce as well. I dont have time to post a photo right now. Pull the fans electrical cord out to keep it from turning on randomly while youre working on it.

This happens because the current through a capacitor leads the voltage by 90 degrees. A simple fix for your fan that doesnt start. Run and start capacitors do not appear to be bulging out however one of them is a tad rusted.

Gave the turntable a little push and then it. These kinds of symptoms would be correct if the motor start capacitor usually inside or attached to the side of the motor itself has failed. During a motors start up a switch connects a capacitor and a special starting coil to the motor.

You may enjoy fiddling and applying wd40 in a strategic spot. The centrifugal switch may free itself over time. And not get wd40 where it should not go.
