2017 389rd furnace fix

[brad2388]

Im currently working on a fix to eliminate the high limit switch cycling problem that a couple of us have here in the forums.

Im using two rule 4" duct fans running to my main living area.

Ive started the wiring of the relay to power the fans. Im currently waiting on the fans to come in.

Ive taken the furnace out and piggybacked off the fan circuit to power the relay that will power the aux fans.

The fans i have choosen has more cfms then the stock fan in the heater.

Added the fans this evening but it didnt totally fix the issue.
The furnace is puting out 155 degree air now. And its not tripping the overtemp.

Now i need to add another vent to get more airflow in the camper. Heading to camping world tomorrow to get two vents. Will report back.

Brad I plan on doing this in my 365saq so any pics and suggestions would be great. I plan on putting mine inline with the 2 connections on the floor duct.
