Solaire 247RKES: Battery or parasite?

I either have a bad parasitic battery draw or my almost new battery is bad. I am getting woken up almost every morning with a low battery alarm.

I ran thru all of the fuses with virtually everything turned off (including the antenna amplifier) and here's what I found (P.S. I am not confident about how the fuses are labeled).
TV: 15A fuse - 15 mA draw
Stereo: 15A fuse - 15mA draw
Thermostat/Furnace: 15A fuse - 75mA draw
Fridge: 15A fuse - 300mA draw
One of my slides: 30A fuse - 15mA draw

The refrigerator, of course, sticks out like a sore thumb - but I don't know what a fridge is supposed to draw. And I can't, for the life of me, figure out why one of the slides draws when resting (I even ran thru the slides and shifted them in and out some and rechecked - still drawing).
Any guidance would be appreciated.

Do you not have a battery disconnect switch?

Battery kill switch

Thanks for responding.

Yes, I have a battery kill switch - but I hope you're not suggesting I throw the switch every night when I go to bed :-) The refrigerator, for one reason, needs 12v to run, even in propane mode.

Sorry, didn't get that you're occupying it now.

Since you didn't say it, I'm assuming that you are dry camping or boondocking.
All modern RVs have numerous parasitic power drains.
We primarily dry camp so we have a dual battery setup and a Honda 2000i to recharge every 3-4 days.

It's almost impossible to get rid of all power drains.

8 hour battery life

Yeah - I expect some battery drain. But I am fully charged when I go to bed, and the low voltage beeper goes off before I wake up. There is definitely a problem.

If you're using the furnace all night, you can easily drain a single battery in one night.

That furnace blower will eat a battery up in 8 hours for sure.

If you only have one battery, getting through the night is tough, especially if you run the heater. We have always installed the biggest 2 batteries we could fit in every rig, from pop-ups to current. We boondock 80% of the time so 2 batteries and a way to recharge them is essential.

Not running heater

No - not running the heater. I have no active drain on the battery. The only draw at night is parasitic.

This is a recent development. It used to be the trailer could sit a week without use before the low voltage alarm went off. Now, it goes off after about 7 or 8 hours.

I don't know if something has happened to some component, or if the battery has gone legs up after only a couple of months. That's why I listed the draw on the different circuits, in hopes you could identify if one of them was way out of line:
a) Is that too much current drawn by the fridge? it is a lot.
b) Why would a stationary slide draw current?

In another forum on FB someone suggested that the battery may not be getting fully charged by the converter. Today I disconnected it from the trailer and charged with a Schumacher 8amp charger. I'll let you know if that helped ... but my two questions above are still hanging - especially b)

I do appreciate your help. I'm sorry if I wasn't clear enough about the situation at the start.

Depending on your fridge model, you may have a door heater that's killing your battery. The door heater is supposed to eliminate condensation around the door. Older fridges had a switch that allowed you to turn it off, but I guess that switch cost them too much - they've now removed it and the heater is on all the time.

Open the outside door on your fridge and look for the schematic. You may see a heater in parallel with the inside light. In the pic of mine below, it's that squiggly thing at the very bottom left side labeled "K".

I've attached a document I shamelessly stole from another poster on how to kill the door heater.

Anyone attempting to boondock should do this mod.
