Coleman DGAA blower fan speed
Hi, I have a coleman- DGAA and split a/c system . just turned on heat for the season in iowa. however the blower will only run on high speed . wires are right on the thermostat & control board if i take the high speed wire off the cool terminal fan won't run , only with high speed on cool terminal , i'm guessing the relay on the board is bad ? also a little bit of a grumbling noise when fan first starts bearing dry, no play in shaft ,wheel is clean

Until Robert replies to this post, does the blower run constantly or only when there is a call for heat?
"Man...that blowed up real good!"
Hi,
Test board and see if you 24vac across W and C.
Then, see if you have 120vac across HEAT terminal and one of the NEUTRAL terminals.
Thanks,
Robert

Some people are Humbly Grateful, while some are Grumbly Hateful.................... Which one are you ?
IF there is a fan run capacitor, replace it first. IF there is no change, then motor is most likely bad.
Can give order info on parts if needed.

Must be 440. IF you ever have one that is 370, replacement can be 370 or 440.
For 440 though, it must be same.
