Fridge on propane

The frig requires power to the control board.
Just wondering why you would shut off the main breaker at all.

I thought breakers were for ac...?

I never shut off any breakers in ours, traveling or not.

12 vdc is on fuses, not breakers.

When driving with fridge on propane do I need to have the main power breaker on to provide the 12v power from battery?

No. When not plugged into 120 vac shore power battery power is fed directly to the trailer's 12vdc system, including the fridge electronics. The 120 vac breakers have no bearing on this function.

My battery must be the issue then, thanks. Propane would not light consistently when traveling. New battery this year, never trouble in the past.

Are you confident your tow vehicle to trailer charge line is working? If not, the fridge alone will significantly draw down the battery if it's not being constantly recharged as you drive.

I was until this last trip. I'll need to figure out a way to test that.
Actually, fridge is running on propane so why would battery drain so fast?

ever check the water in the battery? is it charged? is your converter keeping it charged, ?

You don't have a SIG that indicates which trailer you have nor have you told us in your posts but presumably because you're posting in the Travel Trailer forum that means you have a TT with a DSI fridge. That in turn means that although the fridge heat energy source may be propane you still need 12 vdc to run the fridge electronics, the gas solenoid, and fire the ignition. Since we don't know the make / model of fridge you have we also don't know whether it has a 12 vdc climate control circuit that can be turned off and thereby reduce draw on the battery. Without these details we can only speculate as to what your issue may be.

Fridge requires 12V DC power for controls whether on propane or electric.

Fridge draws roughly 2 amps when operating.......not going to drain a battery OR use much propane while in transit (overnight maybe)

Use voltmeter and test battery voltage
