Dash ac recharge on class a diesel pusher

I did mine last year. I spent the bucks on a proper hi/lo gauge set even. Put in a can of freon. I found that the compressor was not kicking on, even though the gauges said the system was full.

Troubleshooting revealed a temp switch on the ac unit had failed. It's purpose is to cutoff the compressor before things ice up, but it was preventing the compressor from running at all.

I hot wired it.
Replacing it is on my list.
