76 Scamp A/C

I would suggest, you set the temp for off at 40 and back on at 45. At the setting you have now the evap is running below freezing. When we get into summer, the compressor will run longer, and it might slug liquid refrigerant back to the compressor, which will blow the valves, even if the evap doesn't ice over.

I would, but the switch I have doesn't go any higher than 39. He did give me a second one along with the one I bought, but he didn't know anything about it and there wasn't any paperwork with it. All he knew was that he bought it about 10 years ago and never used it, so I might try that one and see what it does. But before this at night, it'd be ice from the expansion valve all the way to the compressor and the compressor itself would be sweating. During the day it's not as bad, but now with this switch on it, it shouldn't do that. Right now it needs a new belt because even though I thought I had it tight, it was loose and ended up just slipping and now it's worn out.
