how to change fan speed on goodman airhandler heat pump multi speed
Make : goodman
Model : aruf
nothing, i have high suction i think fan speed too high.
On the circuit board is where the blower motor wires attach. There are 2 unused wires on M1 and M2. You will want to swap the black wire on "com".
