Hello,
I have a Miller M3RL060ABW furnace which we got back in 2004 it worked great for the first year. When we turn it on it will blow heat out and then it's the blower I think that will trip out and then it only blows out cold air it will do this until I hit the reset switch. It does it often and I'm not sure what the cause is. It seems that it won't shut off the blower at night time only.
Here are few images of my furnace

It's set to heat and fan automatic.
Thanks,
Mark

Inducer high temp switch, check for a restricted flue not limited to anything in the pipe from a tennis ball to toys, bees nest ect
Power is using mind over matter
