Question Converter Questions!

I recently noticed a loud humming coming from the outside vent behind the frig in my 17B. Took it in for diagnosis, was told that the battery converter was going out and had it replaced. Brought it home, still hearing a humming noise, although not as loud. Honestly can't remember if it was ever totally quiet, should it be? Also am now confused about how converter works. If I'm on shore power but battery is disconnected, my frig doesn't work at all--not on propane, not on shore, and obviously not on battery. Why is that? Nor do lights or fan, which makes sense. I have solar. Is battery being charged by solar even when disconnected? I'm so confused!!

The controls in your fridge are powered by 12V from the battery.
Why would battery be disconnected?

Your battery should be on unless you are in storage or maybe need it off for some work being done. Do you mean that you have the master switch for the battery off? Need to keep it on including when plugged in or towing.

You need it to be on when using propane for the refrigerator to get it started.

Yes, you are being charged by solar even if you turn the switch off but usually no reason to turn it off when using the trailer.

I'm guessing that by "battery is disconnected", you mean by the disconnect switch. That would mean that the battery would not charge, but the converter is presumably connected directly to the DC power distribution (fuse) panel, so power should still be available to all circuits (including the refrigerator, lights, and fan). Unless this trailer's disconnect switch is wired unusually, the battery is on one side of the switch, and the converter and fuse panel together are on the other.

It's not clear to me that the converter is working: if the shore power is on, it should be providing power in place of the battery.

Normally, yes. The output of the solar charger is usually connected directly to the battery, not going through the disconnect switch.

Keep that receipt, I have a feeling your old converter was fine but with the switch "off" it was operating 100% time, thus causing a hum from the cooling can.

Unhappy

Up until the loud humming started I had the battery on all the time. (Meaning, the disconnect switch was in the "on" position.) What I don't understand is why, when the disconnect switch is in the "off" position, despite being hooked to shore power, I have no lights or fan, and the frig, despite being set to AC mode, doesn't work. Is that normal? Because I hadn't ever had cause to turn the disconnect switch to off before, I didn't realize that even with shore power I'd not have lights or fan or frig. And, the fan/hum noise coming from the vents directly behind the frig on the outside of the trailer is still loud and I don't know if that's normal. I am perplexed!

Not sure about Escape's wiring, but in many camper brands, 12V DC features continue to run off the battery(ies) even when the camper is plugged into 120V AC shore power. The 120V shore power just keeps the battery(ies) charged so they can keep doing their usual thing (as if boon docking). So if you flip a switch that disrupts the flow of on-board 12V power, no power gets to the 12V features regardless of being plugged into shore power. At least that's true for our current EggCamper.

Yes, in an Escape the battery is still connected to the 12-volt circuits even when the shore power is available and the converter is on (and the disconnect switch is in the normal position). That means that both the battery and the converter are available to supply power - the battery could be charging, or doing nothing, but will only provide power if the converter fails to work. If you disconnect the battery in this case, the converter keeps supplying power; turning off a switch will only stop power to the 12-volt circuits if the switch is between the converter and the 12-volt fuse panel... which seems unlikely, given that the converter and fuse panel are mounted together in one box (along with the 120V AC circuit breakers).

If you turn off the master switch, you have cut the power to everything but solar. That is what the switch is for --- so when in storage you do not drain the batteries. Has to be on to have those things working including when on shore power.

The converter should be supplying 12 volt to everything when plugged into 120 volt regardless of the battery disconnect switch position providing the breaker for the converter is turned on.
