About 5 years ago I bought a cooler/warmer from Sapp Bros that had a freeze protect switch that would automatically shut off the cooler if it dropped below 32 degrees in the cooler. It was a great cooler but then it clonked out about 2 years ago and I havent been able to find that cooler again. Has anyone seen one with the freeze-protect switch. Also it needs to be a warmer too so I can defrost it in about 2 minutes. thx
