Has anyone added a manual control (on/off) to just the fan on a Suburban furnace?
I have a Suburban NT30 in both coaches. When I am paying for electricity at a campsite, I want the electric to heat the coach. A little cube heater usually provides enough BTUs for the temps we camp in, but a single source in a long space is not the most comfortable. I would like to turn on the furnace fan simply as circulation (and even some white noise for sleeping).
Seems like a simple 12 volt source wire could be switched into the line right before the fan. But I don't want to backfeed or mess up the control board.
Thoughts, examples or alternatives for this?
Any suggestions for a replacement bathroom loop booster fan (behind the stove on a GMC upfit) are appreciated as well.
