Nest thermostat will turn A/C for about 1 second, then I get a "No Power" error M20 and another one, forgot what it is. Did ALL the troubleshooting, did a factory reset and set it up again, same thing. Thermostat says the correct wires are connected, app says the wires are connected, and there's 24vAC at the red wire. It has R, G, Y, W and C connected. Got tired of messing around with it and hooked my old thermostat back up. Any help appreciated.
