We went out for a couple hours and came back to no ac. The unit is off as well as the thermostats upstairs and downstairs. We checked the fuses and they weren't off. We tried to reset them, but it didn't work. We are new homeowners and have no clue what to do next.

Try R to G instead. The red is the 24v side. Greeen is the blower. You should also have 24v ac between r and c (brown or black) at the air handler. You can check at the condenser for power also. Turn the unit on at the thermostat and go outside to check thermostat wires between y and common (probably brown or black). Possible a transformer went bad. If it were a problem with the air handler or the condenser, one would run and the other wouldnt. In this case neither run so you have to look at what controls both. I say transformer or thermostat. If you find 24v in either place, its not the transformer.
If you are referring to the secondary pan there could be a problem with your drain line.i would find the drain at the exterior of your home and **** it out with a wet vac..most A.H.Us have float switches or moisture sensors.They will shut down the unit if the drain clogs.
Hey kellyrepp -- Three things to check quickly, so many things can be wrong, but i will try to help with the info you gave me.
The first sounds like your electric aux heat is not wired in or not working correctly , this should kick in when the heat pump cannot keep up with desired set temperature. For sure thats a problem
The second thing i would check is that the compressor for that unit is running. It should sound exactly like the one for the upstairs, the fan noise should be like a whrrrr , and the compressor should be a semi loud hummm.
Third feel the pipes on the outside unit that are on the outside of the unit (the unit for the second floor) Let the unit run for 5 minuites. Now check that the first floor unit pipes are the same tempereture. They are about 110 degrees or so, depending on the outside temperatur , be carefull not to burn yourself. If the lower unit is colder , the two most prominent problems would be #1 the compressor is not running #2 Low on freon.
If it is an older weather king unit (10yrs+) strongly think about replacing it. Known for there problems any expensive to fix. To check the chimney, shut unit off and remove flue pipe from chimey connection. It is always better to have a professional chimney swqeep do it. I really don't think the thermocouple has anything to do with it, it probable does'nt even have one. If the thermocouple is bad, the unit will not work at all.
The motor of your air mover in the inside unit has failed.
It is responsible for circulating the air through the exchanger and your home.
This may be located in an attic space depending on the construction of your house.
Running the cooling with this not working could cause your outside unit to operate continuously or fail.
A more remote possibility is that the thermostat has failed and is only causing the outside unit to run.
sounds like you have a freon leak hence the smel of oil and fog the unit runs because it has a low pressure cut out to protect the compressor when the pressure builds up enought to close this switch the unit runs as thwe pressure drops the switch cut off you will need to have a leak test done on the Evaprator coil inside
