A/C Low Pressure Switch

[mcaden]

My a/c low pressure switch is bad and I need to replace it. Will unscrewing and removing the low pressure switch vacate the system or is there a valve that prevents the freon from escaping? I was hoping to just unscrew the old one and screw in the new one.

Thanks, Marc

Removing the valve will dump the refrigerant.

Jim,

Thanks for your quick response - I was afraid that was the answer. Oh well.

All the best.

Out of curiosity what makes you think it's bad?

I jumped the wiring to the switch and the wire is hot. However, I tested the switch and its bad and causing the compressor not to turn it. It's fairly easy to test.
