Why is my electric fan not moving?
Whether the blades aren’t spinning or the fan is making tons of noise, most issues with an electric fan are caused by poor lubrication or blockages in the vents. To solve most problems with an electric fan, disassemble the fan, lubricate the central pin and bearings, and clean out the vent and motor case.
How do you slow down an electric fan motor?
The speed of Fan can be slow down by simply by connecting a bulb or any other resistive load in series between the power supply and fan. In this method if the watt of connecting Load is increased then the speed of Fan is also increased.
How do I increase the speed of my electric fan?
Check the pull chain switch on the fan. A bad switch, or missing speed setting, will cause the fan to run slowly. Turn the fan off and allow it to stop moving. Pull the chain and turn the fan on the lowest setting, then listen to the fan motor as you pull the chain and move through the progressive speed settings.
What should I do if my electric fan is not working?
With your pin and front motor mostly exposed, turn your fan over to inspect the opposite side of the motor case. On most fans, there will be a plastic vent that allows heat and air to escape from the motor. There will be screws on the back holding this case in place.
Why is my electric car cooling fan not running?
See your “what’s this wire for” thread for an explanation of the coolant temp sensor found in the radiator. No, only comes on when the coolant is too hot. If the belt/viscous clutch fan is moving enough air (assuming your car has auto transmission), electric fan won’t run.
Is it possible for an electric motor to run backwards?
It is possible for some electric motors to actually begin to run backwards. While a typical air handler blower fan uses a squirrel cage fan that does not move much air when it spins in the wrong direction, it will move some.
Why does my floor fan not turn on?
If you turn on your fan and the fan motor hums even though the fan blades won’t move, the cause may be that the gears are stuck. Once you’ve cleaned the fan as outlined in the previous step, try unscrewing the motor housing so you can see the electric motor parts.
Can you run a mechanical fan with an electrical fan?
It’s unlikely you would have room for both, but you should never run a mechanical fan with an electrical fan on the same side of the radiator. If your mechanical fan had a fan spacer, it can be removed with the fan.
With your pin and front motor mostly exposed, turn your fan over to inspect the opposite side of the motor case. On most fans, there will be a plastic vent that allows heat and air to escape from the motor. There will be screws on the back holding this case in place.
How much current do you need to run a fan?
This was a mediocre way of doing things, primarily because the current required to spin the fan was drawn through the switch itself. In electrical terms, that’s a no-no; you should never rely on a switch on the dash to handle the kind of current required to power an accessory that is more than 10-15 amps.
Can you use a dash switch on an electric fan?
In electrical terms, that’s a no-no; you should never rely on a switch on the dash to handle the kind of current required to power an accessory that is more than 10-15 amps. A number of things can (and sometimes will) go wrong, even if you buy a switch that can handle 15 amps.
