On Goodman Airhandler AEPF4260 where are the dipswitches (1-8) located? I assume inside the motor. Is it difficult to access? I want to set back the CFM by turning OFF switch #8 to take off the 10% increase in CFM (back to 1200 CFM from 1320 cfm). Will continuing to run it at 1320 significantly effect my energy savings? I think setting it back to 1200 will make it a bit quieter, also. Thanks

the switches are located on the control board but your ac is required to have so many cfm across the coil and you cant or shouldnt go messing with it.

Thanks, however, it is a variable airhandler that can be set for 3 different tonnages (3, 3.5, 4). Initially I had it set at 1200 cmf (for a 3 ton). The installers had it set for 1800 cfm-like a jet plane in my house! I had to refer them to the install manual and have them set it for a 3 ton. I looked in the circuit board of the air handler and saw no dipswitches. There was a diagram on the blower motor that looked like dipswitches. Is it sometimes in the blower area? Also, am I okay with 1320 cfm for a 3 ton compressor? Thanks again.

You want 350 to 400 cfm per ton. Remove power and wait a minute or two before moving switches to prevent the risk of damage to your board.
I would be surprised to see the switches on the motor.

Thanks for the info-I had switch #7 set to on and #8 to off to get the 10% increase in cfm (to 1320) seems to cool the house better. Even though the standard of 400 per ton= 1200 since I have a 3 ton compressor, it seems unlikely that I would have any problems at the 1320 cfm since it is available as an increase at personal preference. I hope I'm correct! I sure wish there was a diagram for exactly where those dipswitches are located. The techs kind of blocked me out when I tried to observe them changing the settings as I instructed. Thanks again. This has been a valuable and informative forum.

The higher cfm will result in higher humidity.
