I need wiring diagram for goodman AC unit heatpump/electric so that I can wire it up to the thermostat because the wires are not labeled on the end that attaches to the thermostat and I can't find the schematic on the AC unit itself. thanks
The Diagram shows me one capacitor i need one for a 4 wire motor and a 2 capacitor.The Diagram shows me one capacitor i need one for a 4 wire motor and a 2 capacitor.

With a heat pump the indoor fan coil does not have a yellow wire that is true your yellow wiring comes from the thermostat which is a 6 wire or 8 which is also true coming from the outdoor condenser you must connect the yellow coming from the condenser and the yellow coming from the thermostat inside the fan coil cabinet the purple is for heating
the reversing valve has an electric solenoid, if it is energyzed for heat mode, then try replacing or testing the solenoid coil. the coil may be going out drawing more amps than it should.
Incorrect low voltage wiring, or if the wiring is old, most likely a break in the insulation of the wiring creating a short.
First thing, check the wiring diagram to see that all wire colors are attached where they should be at the thermostat.
Then look at the wiring diagram at the air handler and verify the control wires are on the proper terminals.
Heat pumps require a reversing valve for heat operation on the outdoor section, a control signal to a "O" terminal or orange wire is required for heating and cooling depending on the thermostat and out door unit requirements. The thermostat also has to be heat pump type for the system to operate heat for electric system with heat strip, two stage electric heating.
What was the old thermostat labels and the wire colors that went to them?
The typical heatpump wiring Terminals are:
R = Red = Hot side of Transformer
C-B-X = Common side of transformer Depending on brand of heatpump
Y = Yellow = Cooling Contactor
G = Green = Furnace Blower
O = Orange Reversing Valve Energize to Cool
B = Blue Reversing Energise to Heat Depending on brand of heatpump.
W2 = White = Auxiliary Heat
You need to be sure where each wire comes from when you connect them to the new thermostat.
The best way to do that is to go to the furnace and see where they are connected. R-Y-G are probably correct, you need to see where the Blue wire comes from and determine what the X terminal was on the old thermostat.
Depending on the size of your Electric heat you can use one set of wires because your unit does not run with the heat like the heat pump. The large set of wires going to the electric heat should be used. You may have to jumper a new set to the contactor. On Goodman unit come in L1 and L2 jumper to contactor. Very simple good luck. Rus
First,Turn on the heat cycle (Not Emergency)and see if the outside unit come on,If not,and you don't have low voltage outside,Go to the inside unit and test the transformer,If you have low voltage from the transformer but not outside,It is the low voltage wires,If you don't have low voltage from the transformer,It's the transformer.If you have low voltage outside when in heat mode,but the unit won't come on,It's the contactor.Let me know if you need more help.
new unit and old thermostat/wire? thermostat could be bad or bad thermostat wires. try putting in new of anything old. do this wiring practice with the terminals being the letters.
r- red (24 volts)
w- white ( heat)
y- yellow (cooling)
g- green (fan)
Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
R- red
AUX-white
Y- yellow
B- O/B
C- black
G- green
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
170-7
190-1
200-0
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters
