Hello, I am Danny.

Are you asking if there is a system cut-off switch? There is a compressor cut-off switch that will shut the A/C system off when it is detected the system is low on refrigerant. It does this to keep the A/C compressor from cycling to keep from causing damage. After the system is recharged to proper specifications the system will work again. Hope this helps and feel free to ask any further questions. Danny-
