I don't understand comments about it being a low battery.

If he's not on shore power it is.

Referencing Bob213's comment about no matter how the frig is being powered.

I believe when on shore power you need a functioning converter to supply 12v to the control board even without a battery. I could be wrong but I think the control boards are 12v.

My converter has blown both 30 amps fuses and it no longer converts 110 volt to 12 volt DC current. I ordered a replacement. Thank you all for your suggestions.

Check the circuit breaker between the converter and battery. Many have a manual CB with manual reset. However, in many trailers with a three stage converter will maintain the fridge at 13+ volts if the CB to the battery has tripped. So not knowing your trailer model or make or wiring configuration it is difficult to help you. A 3 stage converter in bulk charge will put out 14+ volts and absobtion charge will be 13.5 and float charge (fully charged ) will be 13.2v.

Thank you for the added information.

Enblethen pretty much covered it.

2oldman, could you be more specific? I.e. what voltage should I be looking for if in either cases? Etc.. thanks

Yesterday, my battery was showing 13.3 volts, today it is down to 12.02 volts.

Not sure where the low trigger is for the indicator but fridge should run fine down to 10 volts.

Are you measuring the house battery or the chassis battery? Yes 13.2+ volts would be the normal when plugged in.

Be good to now what kind of rig plus make and model!
Normally I would disconnect the battery, then connect voltmeter across leads coming from the converter, check voltage, record it, then disconnect the rig from shore power, voltage should go away.
Voltage should be over 13 volts when connected to shore power.
I would locate your converter and provide make and model.

How do I determine if my power supply is charging the battery?

Voltmeter

If I disconnect my battery, the fridge does not work on both electric and/or gas.

I charged the battery 2 days ago. It was reading 13 volts. Since then, the battery is going down daily. How do I determine if my power supply is charging the battery?
