Not Another Furnace Question, Yes it Is
I just replaced control board in rig with New Dinosaur 50 along with new Circuit Breaker/Switch and did the pigtail change with the Blue wire from TStat.
Hit switch from OFF to reset and it fires Up! Hooray! I looked closer and saw the idiot light on steady red and went ooops, what's that? I ran it for 5 minutes, heat coming out everywhere it should and went in to turn temp down to 70 (had to go to 84 to get it to come on). Then went back out and light was not on any longer.
Internal Control Failure?
I've looked here and a gen web search and found nothing specific for what that could be.
I mean, brand new board, so not thinking it's that.
Going to hit 17 degrees tonight and hoping it will work, but not sure whether to push it, considering.
