Not really an urgent issue, but I'm balking at the cost to install one of those fancy lower power blower motors, so I'm looking at what I have now.
On my carrier 58STA, there appears to be a few different blower motor speed settings possible. You move around the wires, as per the manual :
Now I can't tell any difference in fan speed between heat, cool, or the 24/7 circulation. If there's any difference, it's subtle as hell.
Mine is set with this following:
BLW: White
COOL: Black
HEAT: Blue
SP1: Red
SP2: none.
So, if my goal is slower, but not off, fan in circulation mode, and lower energy use overall, should I be messing around with this, or just spending the $250 on the fancy Mars Digi-motor?
Don't want fan speed any lower on cool for sure. I already have occasional icing issues.
