Electrolux RM 6501 Fridge freezer

[ChrisMN]

Hello Motorhomers, a newbie here. I woukd be grateful for any comments or help.
Recently purchased a 2003 Rapido and i guess the fridge/freezer is original. It has the automatic energy selector however, when on gas the selector swifch can be on any position, A, O or F. If i move it to F it starts on electric. In fact, it only works on electric when the switch is on F and no idea if 12volt or 240 v when hooked up. A bit noisier too. Very quiet on gas. Is this normal? The electrolux power source selector doesn't make any difference between DC or AC.
Any thoughts please?
Thank you .

As a general rule 12v will only be used when the engine is running, it should switch to 240v when plugged in.

It would help if you post a picture of the controls, particularly the selector switch. It's a old model - Electrolux became Dometic quite a few years ago. I'm guessing the selector switch goes

OFF, AC, DC, GAS, A, F

I don't know what the F position is, but I have a suggestion if nobody else comes up with anything.

Are you aware that when it's on Auto mode and it's using DC when driving, it won't switch to GAS immediately the engine stops? There's a time delay of at least 15 minutes, which is for safety when you stop at a filling station so the gas doesn't turn on and become a fire hazard.

As @DBK says, DC is usually only used while the engine is running. All UK MHs and some non-UK MHs have an automatic cutout that stops the DC to the fridge when the engine stops. That's to stop the battery being drained if you forget to manually switch to gas. But sometimes you want to run on battery, when on a ferry for example.
