Hi all,
I am trying to figure out what might need to be checked or cleaned to fix my furnace "issue".
As long as I have 12.5 to 12.7V on my house battery bank (I have 2 brand new group 31 deep cycles), the furnace blower will kick on and then ignite the burner. Great.
Through the night as it is cycling on and off, it will stop igniting and essentially shuts off completely. I'll play with the thermostat a bit and blower will turn on for 15 seconds or so, then fail to ignite burner. This has happened a few times and I noticed that it is directly related to how much voltage it is getting. After cycling through the night it drains the batteries down far enough to about 12.3V.
Once the solar kicks in, or I start the truck, the furnace will operate as normal.
What should I check here? I am new to RV furnaces. My assumption is that the blower motor is not providing enough air through some circuit and it is a safety feature that is preventing the burner to ignite. However I really would hope that 2 deep cycle batteries would handle at least a night!
Thanks for your help
