First warm weather using my nest thermostat and now trying to use the central air. However, only the fan turns on and it doesn't actually cool no matter how long I run it. (It worked perfectly in the winter with this setup)
Looking at the furnace and NEST, the wiring is as follows:
FURNACE | NEST ------------------ R | RH W | W Y | Y1 G | G C | C
On the Nest, the remaining spots that do not have wires are: Y2, OB, RC, W2 aux, and *.
Any help is appreciated. Thank you.
