Faulty Furnace

Good evening,
Prime Time Tracer 26BH 2021

I bought my camper new in 2021. That same year I used my heat for the first time and noticed when turned on, my heat will stay running until I have to manually pull the fuse out. I will have the furion thermostat set to 72 but by time I felt like I’ve given it enough time to shut down on its own, it’s 90 degrees inside. Well I’m still having these issues. What could be the issue?

I have a 2021 Avenger. My thermostat( pic) has on/off sw plus temp. Sounds like your thermostat is not working. Remove heat wires to see if its thermostat or furnace control. AC is ok?.

On previous camper,heat only thermostat, i replaced it with this one from H.D. Worked great.

New thermostat installed, getting E3 code. Do I need to replace the board?

Here is the E3 Code

Check rhis out! E3 is communication loss…

I do not have have the same thermostat mentioned in the reply. Mine is more basic, not allowing me to “pair” with the thermostat

I think a Furion E3 is a Furion E3 regardless of the model.

That’s fair, and I agree with the E3 on a Furion regardless of model. However I did the E3 error recommendation of a power cycle. Still the same outcome (blowing heat while reads error code 3 and will not shut off unless fuse is pulled). Assuming my circuit board is bad at this point.
