Default AC compressor kicks off under load more so after repairs. What controls this?

Guys I had an engine fire. I replaced the harness and three sensors. The MAF, TPS, and one other I'm not sure what it is located in the same area.

What controlls turning off compressor under load?

Thanks!

This is a 1992 Olds 88 by the way.

Low refrigerant pressure is one possible cause.

Thanks! I'll check that out. Was working fine before the fire though.

Anyone know what turns the compressor off when the accelerator is floored? Is there an adjustment for this?

I wonder if my car has a sight glass window to check freon level?
