Domestic Fridge

[Scooterz]

Need help! So I'm new to this and need help with our fridge. Our fridge has decided to not work this season. Everything was great last year but not so much this year. The LED lights on the control panel are lit but the fridge light inside isn't on. The fridge isn't getting cold on A/C or gas....actually the check light comes on when switched to gas. Not sure what's going on.
Any suggestions!

Be sure your batteries are good, the refrigerator requires 12 volts to power the control board.

Light the burners of you stove to purge the gas lines. If you continue to have a problem, there is a Dometic Diagnostic manual in our Document section on main forum page.

Thanks.....what if I'm plugged in? I've got a battery in there but I'm not sure how good it is.

But the fridge needs both 110ac and 12v battery to work on either gas or electric power...just had to fix a problem with our fridge.

That's correct, needs both. It only takes very little voltage to light up the led indicator, but a full 12 volt to operate frig.

I disagree with having to have both AC & DC. Why even have the two way fridge if you need both? All the AC is for is to heat the boiler. (Unless it has an ice maker). On gas, a small flame provides this heat. Also, if Dometic has not changed, it has to have a minimum of 9.6 VDC.

If your converter is good, it will provide voltage when rv is plugged in.

The computerized control board requires 12 volt to operate regardless whether on AC or DC. Try disconnecting your coach batteries & see what happens, fairly certain your water heater must have 12 volt also.
The frig light & thermistor both are 12 volt.

I really don't understand your argument. I only commented on not needing both AC and DC to operate correctly. And the ability of the converter to provide DC voltage.

If my RV is connected to an AC source, my converter will continue to provide DC voltage. We've had a couple Dometic fridges, and I've done some troubleshooting on them. I do consider them a better fridge than the POS Norcold we have now.

The refrigerator requires at least 9.6 volts DC for proper operation; how
ever, the panel lights will continue to illuminate until volt
age has dropped to 4 volts DC or below.

Page 10 of that document gives the DC voltage requirement for the fridge.

I didn't comment on the water heater requirements, but you are correct, the gas solenoids require 12 VDC. Not sure what the low voltage threshold is on those.
