Thought my low pressure switch was bad, found some thread that mentioned jumping it to troubleshoot. Tried that, thought it was my issue. It wasn’t. Turns out I had a bad hose with a slow leak.

Oh man, that is terrible advice. Unless you verified pressures with a gage manifold, the switch was almost certainly functioning correctly and it was turning off because........the pressure was low. I don't mean to sound like a dick, but using a jumper to "troubleshoot" at described in the video is just terrible. It's like saying "My gas light came on so I removed the bulb. Bam!! Problem solved. Must have been a faulty bulb." instead of checking to see if you need gasoline.

Totally agree, tried to reply to you earlier but I guess I didn’t save / post the reply. Turned out the switch was fine, and I have a leak in a hose.

I will add though, if you're trying to fill a system up from zero and the compressor won't kick on because nothing in the system, that jumper trick works great to get things going and start sucking refrigerant out of the can.
