Nest 3rd gen causing my outside ac unit ti freeze

[MikeSark]

My AC unit is old 2 years old but my thermostat is very old. So i replaced it with the Google Nest 3rd gen. Ever since I installed it the furnace shuts off and my ac unit continues to run and freezes up.
This never happened before. 
I installed per the instructions and I don’t have a c wire. 
I have W, Y, G and the RH 

the old one had a jumper from RC to RH.

please help

Based on your post information, the reason for this issue might be that you don't have a C-WIRE connected to your thermostat.  Here you have this article Troubleshoot strange heating or cooling behavior which describes the issue you're facing and the troubleshooting steps to fix it.
