I think it is the nature of the cheap shaded pole motor, they just cant handle the modified waveforms as well as quality fans do.
Virtually all stovemanufacturers use essentially the same shaded pole fan motors, either made by fasco (also produced with the dayton name) or AO Smith. The thing to remember is that the Coal-Trol uses an automatically controlled speed controller with electronic circuit board VS the rheostat that is used on the Alaska. This would be the key if there are power problems caused by the generator.
Running any stove that is controlled by a Coal-Trol on a generator can result in an issue of the power is not true sine and fairly clean. I would be interested to see what you find with the O-scope. Keep us posted, we always like a good science project!
