Running furnace on Hemisphere 272rl

This weekend I had to use my furnace but it drained my batteries even on shore power. I have an inverter because I have a residential fridge but people on FB are saying I have a converter too. Is this true? If so, where is it located? The batteries were fully charged on Friday when we got to the campsite.

In a 2017 unit you most likely also have a converter. It's normally with the power panel, but they are sometimes located elsewhere.

You need to check your battery voltage with the RV plugged into shore power and with it unplugged from shore power. There should be a difference in the voltage.

You say your batteries were fully charged to begin with. How did you charge them?

All modern rvís need a battery monitor.

A full battery is 12.6 volts. A 50% full battery is 12.0 volts. Reading over 13 indicate the battery is or was charging. Nothing else.

So get out your voltmeter and check voltage anywhere while not on shore power.

Plug the shore power in. While the converter is charging the voltage will be over 13 volts. If not, find out why. Any modifications lately? Loose wires. Fuses blown. Bad batteries? Low on water?

You have a electric furnace? I have a 2018 Hemisphere 29BHHL and I think my furnace runs of propane only. How do I tell? I am pretty upset with forrest river because my furnace vents do not line up with the furnace. I fired the thing up and damn near burnt the trailer. Had to run to home depot and by ceramic heater. I hope get it into a shop to get fixed.

The blower/fan on most furnaces, the thermostat, and the ignitor operate on 12vDC power, although heat comes from burning propane.
