The variable speed two wire switch for the gable mount attic fan is acting up again. Did the same years ago and I got a replacement from Sears Parts. The current Sears replacement (appears to be from KB Electronics) looks really cheap in all ways but price. KB has some better ones but I need to determine capacity needed. The motor is 110v, 5 amp, 1 hp according to the tag. I read online that double the amps is needed to allow for start-up surge. Can anyone advise the capacity needed? I'd like to make this repair the last repair.
