Re: frozen rv

Since you have explored the fuses and replaced the battery, I would remove the monitor panel and make sure that no wires were disconnected.
I would check the fuses with a meter.
Although you have a new battery, is it fully charged?
Check it with a meter, it should have about 12.6 volts.
If the battery has been in for a week or so and you are not plugged into shore power it will have parasitic draw from a few things, and could be dead now.
Come back and let us know what you find.

Peace
Dave

Hi jdya,

If all of your 12V systems are out (refrigerator, thermostat, interior lights, LP water heater, furnace), take a look at our 12V Block Diagram and Diagnostic Guide. The flowchart may help you get to the answer.

Thank you jdya for posting this. We just had the same exact problem and thanks to your post, we were able to find that we had a blown fuse, replaced it and now have full display, the pump works and water heater. When this happened last fall, we thought we had blown the water pump because one of us left the water pump on after all water was gone out of the system during winterization. This saved us a ton of money. Thanks.
