Exclamation Humming Battery Charger

Hi. My concern is my battery charger seems to be running a long time. The humming gets louder. 2013 Thor Palazzo DP. It is loudest in the bathroom and I have no clue how to get to the battery charger. Just dont want any fires. any ideas? it always says float charging. ????? is it suppose to stop at any point? plugged into 50 amps. Thank you.

if your battery is full, float charging is correct. but i would be concerned with the loud humming sound. it could indicate a loosing contact. if you are handy, you can find the location, typically accessible from one of the storage compartments; open up the enclosure to take a look. if space is limited, you may need to remove the retaining bolts and move the unit out to work on.

Your charger contains a fairly large transformer. Transformers are made with layers of iron laminations. After they are mated with the windings, the assembly is held together with (usually) two machine screws. Finally the whole thing is dipped into varnish.

Usually, the screws and varnish will hold the laminations tightly together. Occasionally, things loosen up and the laminations will vibrate against each other, producing a humming or buzzing sound.

Generally, this is fairly harmless. It is just annoying. If it is out of warrantee, and you feel up to it, you can sometimes open the case and tighten the screws.

What is the make and model of the converter,, If you can not get to the converter,, And if your power distribution panel has both 12 and 120 volt circuits (Fuses or breakers) behind a single final door.. What is the make and model of said door.
