Mcdevito75 here, Sounds like the axle shaft that Blades are attached to, broke from the fan motors output. If you can remove the fan guard with the fan switch off and fan un--plugged from the wall and see if you actually pull the fan shaft out of the motor. Even if you could fix this, the cost equals a new fan.

These run very small motors with low "starting torque" If the fan hasn't been run for a long time, its possible that it has jammed up or got tight from just sitting there. Being careful, turn on the fan and spin it in its usual direction by hand, it should start running. If you cannot spin by hand, it may have seized up which will require you to strip and lube the motor. If you manage to get the fan spinning , let it run on high fan speed for an hour or so, it should free up and then be OK again. A small spray of WD40, CRC or similar spray can lube on the fan shaft where it disappears into the motor may assist.

Pedestal fan will not run.


The cost of repair probably probably will make replacement more feasible.

My fan is not rotating when I connected to plug. There is no burning smell or anything. How can I fix the problem? Thanks in advance


Hello.

I have a Holmes pedestal fan that does this every few years. I have had this fan for about 10 years.

Unplug the fan and remove the fan blade guard. The fan blade should spin easily when you tap the edge of the fan blades with your finger. If the blade barely moves and abruptly stops, the bearings are dirty and need to be cleaned and oiled with 10W non-detergent motor oil. A quick-fix is a tiny bit of WD-40 where the motor shaft (the rod that the fan blade is mounted on) meets the bearing (the part of the motor that the shaft spins on). To properly fix this, you must oil both the front and back motor bearings which requires removal of the motor housing.

If the fan blade spins easily and you are certain that the fan is getting power (try a different outlet) the motor may be bad. Likewise, if the fan blade will not move at all. I do not know if Holmes sells motors for these fans. Here is their online support website:

www.holmesproducts.com/Support.aspx

Good luck from Detroit, MI.

P.S.: Never turn a motor-operated appliance on for more than a second if you know it's not working. That will cook the motor windings.

Have an expensive Hunter indoor/outdoor pedestal Fan that stopped working. It just "hums" and does not turn. Please help.


With the fan UNPLUGGED, try to spin the fan blade with a pencil or something that will fit through the blade cage.

If the blade spins easily, there is an electronic problem (control or motor) that must be serviced.

If the fan blade is stuck or very hard to move, the shaft and bearing are probably dirty and need to be cleaned. You can temporarily fix this with a tiny amount (a drop) of WD-40 applied to the shaft where it enters the motor. Spin the blade manually to work the oil into the bearing. If the motor spins freely, the dirty bearing condition is verified. To properly clean the shaft and bearings, the motor must be disassembled.

Dayton 30' pedestal fan will run for an hour or so, seems to run hot.. there is slight burning smell. then fan makes little noise and shuts down.


Whats happening is that your fan is overheating (usually due to a loss of lubrication in the bearings), and the motor's thermal cutoff is kicking in (due to overtemperature), and shutting down the motor.
This thermal cutoff circuit is installed in consumer motors to prevent fires.

You have two solutions:
(1) disassemble your nice 30" pedestal fan (I've done this a few times - any handy guy/gal can do it),
and lubricate (with automotive bearing grease ($3 at any auto parts store), or 3-in-1 oil for those spots that won't take bearing grease) the bearings, and
reassemble. Re-lubricate on a regular schedule to prevent recurrence.
(2) buy a new one. Give your old fan to the kid on the block who thinks he/she can fix anything &
tell him/her it just needs to be lubricated.

Not sure which pedestal fan it is. Speed is a dial, not three distinct speeds. Just found and cleaned it, but now it will not start up unless I spin the blades by hand 6-10 times to get it going. Seems...


Here is a write up I did for Humidifier fan motors---
the same principle applies to pedestal fans, too-- You are right-- the bearings get dried out-- and the shaft 'STICKS!!
Let me know what you tihink of this write up-- try it and let me now what I left out-

Mack B

Have you considered checking to see if the fan motor might just need cleaning and lubricating?
Most small fans and heaters, have small fan motors, in which the bearings have dried out over the years. If you have made an electrical check on the motor leads-- and you have electric going into the windings, likely the motor feels warm? (If not-- possibly a bad splice where the supply wire attaches to the tiny armature wires?-- check , and check continuity)

If you want to tear into the fan motor, and clean up and lubricate the bearings-- here are some tips:

First you need to get inside the heater of the fan housing-- by removing the protective covers.
Note the screws, sizes, locations, and how the protective covers will go back on when you are ready to reassembly-- Mark where the screw holes are that line up with the matching other parts.

Then remove the motor from it's bracket (Possibly have to remove the fan first?)
You will have to remove the fan, to lubricate both front and real bearings.
Next you will need to remove the 4 long screws that hold the motor frame together-- Be sure to mark the original alignment, so you can reassembly correctly.

Now, with the fan removed, gently separate the Front and rear half's of the motor. Usually the windings will stay with the portion of the motor where the wires are still attached. Either way, you are going to have to get the bearings to slide off both Shafts of the armature-- without breaking the delicate winding wires-- the wires are hair thin on small motors!

Now clean up the caked on residue on the shaft where the bearings ride, with rubbing alcohol. Clean up the internals of the bearings as best you can- making sure the pores of the oil-lite bearings are not plugged with solids. Now begin the gentle process of getting the bearing wicking to soak up new oil. When you are sure the reservoirs are well saturated, then generously lubricate the shafts, and slip them thru the bearings again-- retracing all your steps above, The motor shaft should turn freely now. You can test the motor without the fan on-- to be sure you have the motor itself reassembled properly.

Double check all the splices, switches, and any high temperature limit switches for continuity-- and trace the wiring all the way back out thru the power supply cord.

What did you find, and what do you need to do next?

Holmes "16 fan needs to be lubricated. Where do you add oil


Hi,
No there is no way to lubricate the new cheap fans internally...they are made to run for a bit and then be thrown out...
I have found that by using a thin oil like WD-40 and then positioning the motor so that it runs back the shaft into the motor you can get it to work into the motor. I usually use WD-40 and then follow with a light motor or sewing machine oil. This seems to give a longer solution...
