A/c unit runs but only blows into the house for about 30 seconds

My gsm9/gcs9 goodman unit is not working very good. when the a/c starts it only runs for about 30 seconds and then stops. the unit part that sets outside will run but the blower doesnt seem to work that good. i removed the panel and checked the fuse and it looked good. so i dont know. i put the panel back on and again only ran for about 30 seconds or so.

Shut the power off to the unit, spin the fan blade to see if it spins freely. If it doesn't spin freely, (there appears to be a little drag when you spin it),the bearings are bad, if it does spin freely, then try moving the motor shaft from side to side if there’s any play in the shaft side to side then the bearings are worn and motor needs replaced. Then, check the capacitor, if it’s bulging even slightly, the capacitor is bad and needs replaced. Most of the time people replace the capacitor if motor seems ok. If capacitor is ok, turn power on to see if the motor is getting the proper voltage, if it is and not trying to run, then the windings are probably open, the motor's bad and needs replaced.

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


Yes.
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. :-)

Goodman GS9 propane furnace inducer motor runs continuously


it sounds like the low temp limit switch, the one that cools the furnace down with the burner off and the thermostat open, when it cools to a point the fan stops, the other switch in burner area turns burner off/on, hope this helps

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.

Fan not running on Heat Pum


That does not sound normal at all, I have a Goodman Heatpump and the Fan on the Evaporator (outside unit) should run as soon as it starts up!
The only delay you should be seeing is when the unit starts, the fan in the AHU starts 5 seconds after and runs for about 1.5 minutes after shutdown.

Fan runs but blowing hot air. Thunderstorm reset some breakers. I did reset the two breakers inside the house and one unit working fine, upstairs unit fan running but blowing warm air only. Box out


Sounds like your Capacitor is bad, or you had a wire burn off compressor terminal or capacitor. Way you can check capacitor is take cover off and see if looks swollen. Make sure to turn off power before taking panel off.

How to manually relight a Goodman® GMS9/GCS9 Single-Stage, Multi-Speed Gas Furnaces


You should NEVER attempt to relight manually this furnace. Serious burns could be the result. This furnace has an electronic ignition and should light by itself. If it does not light you may have a bad ignitor. These are usually around 30-50 US dollars.
