Frozen AC Coils
I noticed that my outdoor compressor was running a lot but no cold air was flowing my my vents. Upon inspection, I found that the coils were frozen as well as the line connected to the compressor. I tried turning on the blower fan in the furnace but no luck. When the thermostat is in heat mode the blower fan will turn on but not in AC. Right now I have everything off and defrosting. The system is a Bryant 90. Any thoughts?

The model number is 350MAV 048080ADKA
I don't have a multimeter but can get one. I'm fine with live electricity.
I just tried it again after warming up overnight but no change. When starting, you can hear a click like a switch wants to turn over but isn't.

I'm mistaken in that when the heat turns on, the inductor motor runs. After letting the heat run for a few minutes, the blower motor never kicked on.

I just tried running the AC and giving the blower a push start to see if the capacitor was dead. No luck.
