, posted Tue 5 Aug 11:48  
I have a Goodman A36-15 Air Handler/Heater. The A/C unit outdoors kicks on and everything is working except the Blower fan is on low setting. It does not push the air through the vents. You can only feel low pressure but air is cold. Also causing a lot of condensation on the coils, which caused a blocked drain pipe and leak.
Any ideas on how I can fix this?

I believe the 3 ton unit comes factory wired for high speedbut this is not hard to verify. If black from your motor is capped off, you are using low speed, if red is capped off you are using high speed. (See note 1)
It is also possible that the evaporator coil is dirty or the cap is weak.

Thanks for the diagram. The red is capped off. After I posted I took the unit apart to see if I could increase the speed of the motor. I found that the lines were frozen. I let it thaw and it seems to be blowing alot colder and stronger.
The unit had to run from 94F to 80F overnight so I don't know if this is what caused it to freeze or not. Maybe low on Freon??
Thanks for the help.
