Heater update

[craig333]

I thought we had a heater thread pinned. Must be my CRS. Anyway, I mentioned on my last trip my heater didn't function. The batteries were low but not dead. Charged them when I got home. Heater connects and fires up. Okay, the thermostat doesn't like low batteries. I'm still thinking my igniter may be not working correctly with low voltage conditions. I thought about firing up the truck and seeing if that would do it but I didn't want to bother the other campers. Igniter board slowly failing or am I fishing in the wrong pond?

I'm thinking you may need a new battery. How does it test out on a load tester, assuming it's not brand spanking new?

My heater will not ignite on a low battery either.
I think this is normal, but I don't know the details.
As soon as you fire up the truck or charge the battery a bit, the heater will function normally.
