SOURCE: My cast iron original hunter ceiling fan needs a
Howdy,
There are a couple of issues which can cause this with the Original. First, is this an American made fan, or a Chinese made fan? The main difference between the two is the motor type. The Chinese version should have an "A" after the model#.
First question, when you turn the fan off, how long does it take to come to a stop? From high speed it should take at least 60 seconds, from low at least 20 seconds or so. Also, are you trying to start this fan from a wall switch on low speed?
The first issue which can cause this is oil level, I know you say it has plenty of oil, but, depending on how you checked it, it may not be enough in the reservoir. To check it, you take a pipe cleaner and bend it over to form a J with the hook portion being 3/8"-1/2" long and dip it into the oil cup at the top of the switch housing as said in the below links. Remember, if you have a Chinese fan from 2002-2007 (after 2007 there is a brass cap on top of the motor where you add the oil and it functions the same as the American fans), the oil hole will be on the switch housing and you must lean the motor over to add oil, if you add it with the motor level there will not be enough oil in the reservoir. If you are indeed full of oil, run the fan on high, and with a LARGE screwdriver used as a stethoscope, remove the switch housing cap (two screws) and insert it all the way to the top of the switch housing and put your ear to the other side of it, then turn the fan off and while it coasts down listen. You should hear very little noise if anything at all, it should be totally smooth oil if circulating through the oil system, if it sounds dry and gritty or like metal on metal, then oil is NOT getting to the top of the armature. If this turns out to be your problem, I can help you fix it.
The second issue which could cause this, is the capacitor is getting weak and the motor isn't generating enough torque to start. I think this is fairly unlikely as I have never seen an Original with a bad cap.
The third issue could be that, if the oil is where it is supposed to be and if you have tried putting an extra snort in the oil hole and that doesn't cure it, that something has gotten into the oil reservoir and is binding the bearing up. Bugs seem to love the oil cups of these fans for some reason and I have discovered wasps, beetles and flies in the oil cups before when dis-assembling these fans for repair. If you have exhausted the other possibilities, remove the fan and drain the oil out of it, shake the fan a few times to make the rotor bang back and forth and then re-install the fan and re-fill with new 10wt oil. (do not use 3-in one oil in either the red or blue can, both of which contain napatha)
If you have the American made fan, this is the owners manual http://www.hunterfanhq.com/tools/sales/hunter/preseason/images/owners/41532.pdf
If you have the Chinese fan, this is the owners manual for it http://www.hunterfan.com/uploadedFiles/Support/Owner_Manuals/41556.pdf
If this is an American made fan, it's worth repairing, if it is NOT an American made fan and after troubleshooting it and not finding a fix, I recommend calling Hunter and warrantying the unit out. The motors carry a lifetime warranty.
Testimonial: "Thank you. The fan is running great now! It is the American fan. Bugs must have been the problem."
SOURCE: where can you buy 10w non detergent oil for use in
I found Kendall 10w non-detergent oil on Amazon. Unfortunately you have to buy a case of 12 quarts for $50.
