Is the refer in a Slide room? When you say it started working again, THAT is a subjective opinion. What was the freezer temp? What was the actual lower refer temp? The temp for the lower is to be taken in a glass or water after 24 hours on MAX cold setting. Cooling units can be harmed 2 ways. Run OFF LEVEL for over 24 hours. OR, IF you have severe heat and inadequate or NO cooling air up the rear coils, you can "BAKE" a cooling unit which the result is the same as OFF LEVEL. Then you have to replace the Cooling Unit. Baking a cooling unit takes less than 24 hours if NO AIR FLOW AT ALL. If you had air flow but the 115 heat caused a flow problem, I will bet you are OK. Doug
