Yep, they do. Which Thor MH has one in it? Maceman does not have one in his ACE, the OP (who started a thread about batteries, not fridges) doesn't have on in his Siesta. So who in this thread has a 12 VDC compressor fridge that Maceman's comment was directed to?

His comment was misinformation for 99% of the RVs in use, and all RV fridges that have "an indicator light for ac".

I have never been in any of these posters units, so I do not know what they have. I just pointed out your vague comment.

Is being demeaning part of "Site Team" requirements?

Probably not. He has a motor coach.

Not meant to be "demeaning". Meant to stop the spread of misinformation. People come to these forums for many reasons, but one of them is to gleam information about their own RV. Reading a blanket statement about RV refrigerators which doesn't apply to the thread or even to 99% of the RV fridges does them no favors.

Kinda makes me wonder why you want to prop-up the misinformation?

If it's the typical rv 2 way fridge (Dometic or Norcold) it WILL/DOES operate on 120 volt ac or LPG but requires 12 volt dc, from either the batteries or the "converter", to power the control board whether running on gas or electric.
If it's a residential fridge it will only operate on 120 volt from shore power, generator or by 12 volt dc through the "inverter" from the batteries providing 120 volts. Better have a good strong bank of batteries &/or good solar panels to run by this method for extended periods.
In the past 12 volt only fridges were found in small entry level RVs, but are coming back in some RVs, but if I recall not too many offering them yet.
As for the OP it sounds to like your batteries are toast. If replacing them be sure to replace ALL at the same time with identical batteries, if not the old battery will, sooner than later, canabalize the new battery thereby shortening it's life span much quicker than normal.
If storing the rv for any length of time the best way to stop the parsitic drain is to remove the negative cable from the battery that goes directly to ground or add a total disconnect device to that cable. The Use/Store switch DOES NOT totally disconnect the batteries!
