Low on freon, or presssure cut-off switch bad. Easily replaced. LS has 4 wires, GS has 2 wires. On the GS shorting the wires will tell if the switch is bad. Not sure on the LS which wires.

Check/replace the over-pressure cut off valve. It sticks right up on top, easy to get at and replace.. Has a schrader check valve, I think (saves freon) You can check it by shorting the wires together, and see if the compressor runs.
