DGAA090BDTA coleman
hey I'm working on a furnace Coleman DGAA090BDTA and its telling me that the pressure switch is bad. with a little suction i can hear the switch work so i am wondering if it could be something else or if the switch is bad, or how i can tell what it is exactly????
If it says the pressure switch, it could be the switch itself, the booster motor, the tubes, the air pipe causing switch to not close.
You would have to test the water column pressure to see if it is switch or motor.
Thanks,
Robert

how do i test the water column pressure? ...... i have checked the tubes, and they are like new. and it sounds to me like the booster motor is running just fine.
You would need special tools and equipment plus experience to test for that.
Test the pressure switch and see what voltage it reads across the two connections.
Does it read 24VAC and then drop to 0VAC or does it read 24VAC always ?
If it reads 24VAC at all times and booster motor sounds to be running full speed, most likely the switch.
Without a Tech to test it, you would have to decide whether to replace switch or not.
