My unit sometimes emits a loud hum - usually when minimal power is being used. Is something wrong? How do I fix?
It is the 50 amp built-in model that has been in use for almost 2 years. It has "found" and saved my RV from four "open ground" issues and two "neutral-hot reversed" campground pedastals.

That is great to hear that this EMS-HW50C has provided substantial protection. The hum is sometimes normal to hear based on how it is mounted. You can go to Progressiveindustries.net and under the resources tab is a warranty tab. You can fill out the warranty claim form and submit it to see about getting you a replacement sent out.
