I have an Emerson 30" Full House Fan - WHF 1130. I am adding a variable speed control to the fan. How many AMPS is my motor for this fan?


Thank you for your question on the amp draw of the Emerson whole house fan.

The fan circuit will have to be rated for 15 amps even though the fan does not draw that much. If you undersize the variable speed it will overheat and fail.

I will give you the variable speed control that they recommend for the fan motor.

Variable speed control for the fan motor .

I hope this will help.
