II have a Dayton 1/2 HP two speed attic fan. The high fan speed is out. I am not sure whether it is the motor or the speed switch, but I have a use for the slower speed, which raises a question. A fan at half speed uses less horsepower. Is it likely that the two speed switch also reduces the HP at the lower speed.?

Answers

Answer: 
The two speed switch only changes the magnetic field characteristics by supplying the power to different taps of the motor windings. The switch in and of itself does not not control HP. HP will drop in the lower speed in keeping with when less work is done, less energy is required to perform that work.

The circuit sometimes blows when the fan is turned on. I have replaced fuses 3 times. The unit is a 2 speed belt dive Dayton system. The blade/motor rotate freely and there is no bearing or bushing noise when it does work. This unit has worked flawlessly for many years. Are there any electrical contacts that might have become corroded, creating high resistance?

Answer: 
This problem can be caused by a number of things. The first thing to check, is to make sure that the circuit that this motor is on, is not overloaded with other devices, that would be the most common reason for this problem.
