Goodman Furnace GMS9/GCS9 Blower seems to not be made very well. The repairman put two different ones on before finding one that's somewhat balanced. I still feel it rumbling a little. Are there

It is possible it is a problem with the motor mounting bracket or the fan housing itself. Tough to believe you have gotten three bad blower wheels. Also could be the motor .

Fuse blow each time I turn on air check for

disconnect the thernostat wires from the control board. Put a jumper wire between R & G put door back on and turn on power. Blower motor
should run, if it blows the fuse then you have a direct short between R &
G at the board. Do this with R and W(heat) and R & Y(cool).

By disconnecting the thermostat wires and reinserting them make sure that they do not touch when inserted into each terminal. If it still blows
that little 3amp fuse when jumpering between each sequence as mentioned above, then I think your board is bad. When Jumpering out the Y terminal you will have to have the AC wires still hooked up. If it
blows the fuse in that sequence. Disconnect the wires out at the condensor.

You mat have a bad contactor at the outdoor unit.

Fuse on control module blows when calling for cooling

Disconnect the the red and the yellow wires at the outdoor unit. Then replace the fuse and turn on the power.......see if the fuse blew. If the fuse blew, your problem is most likely a short in the low voltage wiring. Check for crimped or damage wire or wire insulation and repair as necessary. If the fuse is okay, then the problem is within your outdoor unit.......again inspect all wiring for any damaged insulation or crimped wiring.
Check these items and let us know.....we can guide you further after you perform these checks. :-)

My furnace heats the house well, but during the cool down it actually blows cold air dropping the temperature causing the furnace to re-ignite. How do I adjust? Goodman - GMS9/GCS9

Depending on the age of the furnace you may be able to adjust the cool down. On some furnaces there is a silver box usually made by honeywell. This is your fan limit control. If you take the cover off you will see a dial with different temperature settings with 3 pins in a grove. The first one is fan on with temperature rise this turns the blower on when the furnace starts and warms up. The second is the fan off after furnace shuts down, this would be the one you want to adjust to a higher temperature to keep the blower from blowing cold air. The last pin is the high limit if the furnace gets to this temperature it will shut the furnace off but keep the blower running. Make sure that the thermostat fan option is set to auto and not on.

Constant high pitched noise emitting from furnace

This is probably a dry bearing in the vent motor. Those motors run at high RPM's and can make a deafening high pitched squeal if they become dry and need oiling.
Some of the motors have oil cups on them for dripping oil into and others;s are much more difficult as you need to guess where the bearing is and try to drip oil down into them or run the oil to them.
Any light weight small motor oil ike a sewr machine oil will work.
Many hardwares have small oil bottles with extending spouts made just for oiling motors for just a couple of bucks...

The other thing that can cause this is if the blower wheel is coming loose and has moved to the side and is hitting the side of the blower housing. Take the bottom cover off and check for play or movement side to side in the blower wheel. Spinning it with the power off by hand may give you a clue as you will hear it scraping the side of the housing.
