If it has been to the "shop" and they state it is good, WHAT ARE THE TEMPS THE SHOP REPORTED? The ONLY test for the lower section is a glass of water after 24 hours with the 120 element wired direct to 120 volts. THIS will tell you the condition of the cooling unit. The FREEZER will get extremely cold within a few hours but the lower section will take 24 hours. 24 hours is the required time. NO SHORTCUTS. If you have had the refer in the shop and told them about the failures, they should have told you the water temp after 24 hours hot wired. The Freezer should be 0 to 10 degrees after 24 hours. The lower section the water in the glass should be at least below 36 degrees. 36 to 40 is marginal and indicates a partially block Cooling unit. Anything above 40 degrees the cooling unit is blocked enough to prevent adequate cooling. Make sure the AC line voltage is above 115 volts. Doug
