|I spent the afternoon trying to make sense of what’s causing my new-to-me Emerson 16646 to pull so many amps. L/M/H gives 1.6/1.7/1.9A on the Kill-A-Watt with a much slower start-up on high than low speed. It runs warm after just a few minutes, even with a smooth 50 second spin down. The problem is not mechanical in nature...
It turns out that the motor stator Start lead was soldered to the Low speed tap rather than the dedicated 4th phase shift tap I've seen on my other Emersons. It seems the phase shift lead wire was broken off the speed coil sometime in the past. The plug and headwire on the fan are old but not original and it was a second-rate job, missing coil tap non-withstanding.
The bottom line is that I need this coil rewound properly with all 4 taps accounted for. I know Tom Newcity and Rick Huckabee offer this service... can either repair the cracked switch base and split insulated speed lever cover? Is it possible to have it rewound to account for modern 125V power and give a greater separation in speeds?
