I have a Trane TWE030P13FB airhandler. Anyone know how to change the blower fan speed on this airhandler. I am knowledgeble about electrical work and want to tackle this myself. I think the fan speed is at the highest right now. When the AC runs, it is too cold and once it is stops the house gets stuffy . I want to reduce the blower speed and see if more moisture is absorbed. :D
If you open the air handling unit , look to see if the blower motor is a direct blower., I am sure it is.
The motor will have different color wires attached to some kinf of switching relay.
The black wire is usually the high speed .
If you want to lower this speed , remove the black wire (high sprrd ) and tap it so it doesnt arc out.
Look for a the orange wire . This is medium high. ( next speed down from high) replace the orange wire where the black was.
Now watch to see if you get more moisture out of your sysstem.
Warning " When you lower the speed of you blower you are also not boiling as much refrigerant. You have to be careful that no liquid gets back to the compressor. . Low speed fan can cause slugging.
As long as your AC coil has a TXvalve you shouldnot have any problems.
