Loud noise - transformer(?) CircuPool Universal Series Salt Chlorine Generators - Owner Resources Universal Series

My control unit now makes a loud humming noise when the unit cycles on. I don’t remember it being this loud before now. Is this something to be concerned with?

Noises from the control module of a CircuPool Universal Series Salt Chlorinator will almost certainly indicate a PCB cooling fan that is beginning to fail. Reach out to at (888) 206-9938 Mon-Thu: 9-4:30 (CST) or Fri: 9-3pm (CST) and a member of our technical support team will assist you.
