I was just out in my white hawk and noticed a high pitch buzzing coming from the inverter. I have the camper plugged into a 30 amp plug at my house. When I turn on two different light switches the sound almost goes away but as soon as I turn them off it comes back. Any ideas?
Our 2015 whitehawk 28DSBH has done it since we purchased it new. It only happens a few times every season and usually stops after i flip the main breaker a few times.
