2015 Reflections 337 RLS Humming Noise

[Lippend]

Good Morning,

Our camper, 2015 Reflections 337RLS, is parked under its camper port and plugged in to 30 amp power. Nothing is on, but when checking it this morning, I could hear a humming noise.
Turning on the overhead lights would start the inverter, but didn't change the hum.
Anyone know what I'm hearing?

Is it your refrigerator fan? Try turning off the refrigerator and seeing if the noise goes away.

We keep ours plugged to 30 amps when stored and there is a hum that is the refrigerator.

Thanks, Jim, but not the Refrigerator, it is off and door are open.
Hum is louder in storage area, so it is something behind the back wall.

Thanks Ellen and Jerry, but refrigerator is off and doors open.
It is something behind the back wall of the storage area since the hum is louder there.

It's normal to have a low hum from the converter which will increase as you add more 12v load such as lights. Try turning off the circuit breaker for "converter" to see if the hum stops.

Simply the battery charging will make the converter fan run at varying speeds depending on charge rate thus having fan converter noise when the battery switch in the basement is on. Try turning your battery switch off along with ensuring all other power draining items are off or not running and see/hear watcha got !.......s/b much quieter.

​Is there any chance the water pump switch got hit, if the tank is empty it might sound like a hum
