I ALSO REPLACED MY COOLING UNIT WITH THE AMISH COOLING UNIT. IT LASTED ABOUT 1 YEAR SO I CONTACTED DAVID FORCE HAD A REPLACEMENT SENT OUT. THEY CHANGED THE DESIGN AND THIS ONE SO FAR IS PERFORMING GREAT. HOPE IT KEEPS RUNNING.I HAVE MY FRIG.SET ON 5 AND NO PROBLEM EVEN IN THIS HOT WEATHER IT STAYS AT 40 IN TH BOX AND MY FREEZER IS BELOW ZERO.
