My A/C blows hot air was working and then quit blowing cold air. Hook a gauge set to it low side is 100 psi when running and high side is 150 psi. What is the problem just low on Freon?

That means your system is static when the pressures are equalized. We need to suspect a possible control issue or compressor.

I suspect we have a power issue so we need to start with jumping power to the compressor to see if the compressor will come on. Let's start there and see what we get.

Here is a guide that will help with what we are doing:
