When we turn it on, we hear a loud whining noise that overshadows the sound of the organ. It works, air is going through, but this noise is there. We put oil in itk, but that didn't help. Any suggestions??

The whining noise you hear coming from the power steering pump is one of three things. The first is more of a loud "hush" than a whine; this is the sound of fluid rushing through the bypass valve when you turn the wheel all the way to one side or the other. Sometimes the bypass valve malfunctions or doesn't open all the way, causing pressure to back up in the pump and cause your engine rpm to drop. The second and third causes result from cavitation -- vacuum pockets created behind the rotor's vane blades as a result of extremely high pump action -- or air in the lines.
The Hammond is a great organ. I believe you have the star+ter on your organ. If you are unfamiliar with it, you need to hold the starter switch up and let it spin up to speed, then switch the power button to the on position while simultaneously releasing the starter. If you already are doing this, you may have a bad starter. If the star+t++er is working, check the connection to the speakers.
-After paying an LG serviceman for a home visit, I told to refer to the manual-and there in small print-USE ONLY POWDER CLEANER. Gel and liquids make too much bubbles(thus air) in the hose producing the noise. It will take several washes-but the noise will go away!
It is probably so kind of interference from the rotary switches. It is in the shielding of the Hammond organ. You might try some aluminum foil around the unit certain areas at a time which will give you an idea if it will help and what areas need to be shielded. If that does the trick you install the aluminum foil shield inside the chassis. Hope that helps. Let me know..
sounds like your bearings are out on your fan motor. Some of the older fan motors have places where you can oil the bearings but most newer ones do not. Unless you have a place to oil the bearings and they are not already too far gone you best bet will be to replace the motor. Once the bearings start howling in the way you described it is time to start looking for a replacement. It is also possible (although unlikely) that the noise you hear is (a) the fan blade hitting part of the frame. (b) the bearings in the compressor.
Lubricate with OFFICIAL Hammond oil immediately! Then let sit for a couple weeks. Manually turn the generator and add lube as needed until free. If bearings still sticky, put a bit of CRC226 on them individually and free them, then lube with the hammond oil via the wicks.
CRC226 is available at Home Depot in electrical dept.
