A question regarding an impending attempt to replace the control board in our furnace myself.
Extenuating circumstances: Approaching Arctic Cold Front.

The story so far:
~ Furnace breaks down: fan won't come on.
~ Repairman comes and diagnoses problem: Control board frizzed
~ Good news: We can use furnace by keeping fan turned on all the time. Heat cycles normally.
~ Kind repairman mentions: I can find a control board online and replace it myself for WAY cheaper ($118 vs $900+)
~ Control board ordered and will arrive tomorrow.
~ Arctic Cold Front will also arrive tomorrow with temps close to 0 degrees.
So... I'm pretty confident I can replace this thing. It appears to be simple moving of connections to identical connections on the new board - one at a time so there's no chance for mix up.
But, I've never done it before. AND, it's going to be big-time-cold tomorrow when I get this board.
1. Go for it, and hope it works. If it does not, I'll be without heat. I can try to replace the old board and restore the limited functionality we have.
2. Wait for a week+ for warmer weather (predicted) and do it then in case it's a bust.
Furnace saavy Mefites: Have you ever replaced one of these thangs? Do you know the ways of furnaces? What do you suggest?
