Question about Goodman Heating & Cooling
Not turning on at all. Anyone has suggestions? I have already check for cloggs and all clear. I hear a humming when I turn on the plug switch so power is coming. I even used a drill to test to see if they outlet works and it does. All electrical seems to NOT be loose. Thermostat is working properly and the fuse inside the furnace is still good. Fuse in the main fuse box still good too. Any suggestions before I fork out money. This unit is not even 3 years old.

Test while the unit is firing with a meter. you should have 24 volts going to gas valve. If you do and no gas is coming out, you have a bad gas valve. You will need a gas pressure test kit to install a new one correctly.

I had the same issue as zippygaloo with the harness plug. By lifting up the connector, the furnace would go out of it's current fail mode and start operating normal again. I have temporarily resolved my issue, by tying up the wires (looped under them with tie raps) and secured them to the vented furnace housing directly above, thus alleviating any stress pulling down on the connector plug by the weight of the wires. Since doing this my furnace has been running flawlessly and stays right at the temp on the Tstat. No more fault modes with blinking lights! Hope this helps you guys. I don't know if it's related to bad design flaw, or there is a weak connection on the board, but it worked for me.

I had the same problem. I had to remove a return air duct filter that i had installed and it worked just fine. The system needs plenty of air flow to operate.

double check your wiring. R terminal on the furnace will provide 24 volts to the t-stat. W terminal in the t-stat will send 24 volts back to the furnace W terminal to turn on the heat. G terminal in the t-stat will send power to the G terminal in the furnace when the t-stat is switched to fan on. Y terminal in the t-stat will send power to the Y terminal in the furnace which in turn will send 24 volts to the A/C outside. The C terminal in the furnace should be connected to the c terminal in the A/C outside as well as to the T-stat. Check the fuse again
