Freezer door was accidentally left open for about one hour. Now the refrigerator and freezer are not cooling.

If the freezer or fridge door remains open for one hour or few more hours by mistake, then to again get to its proper cooling cycle, it requires approx another 24 hours.And in that also, dont open the refrigerators doors for few hours.If you open, close it quickly.Once it cooling cycle again gets set, then you can use it like you use regularly.But approx it takes 24 hours to get proper cooling.-------- ------------------ But if its already more then 24 hours and there is very low cooling, then it can be internal defrost cycle issue.You will have to do manual reset procedure.The manual reset procedure is as follows:-------- First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take near to 4 hours to get run in its proper cooling cycle. Then check,it will get set to its cooling cycle and work as normal.------------- This should help.Thanks.Helpmech.
