We have a Maytag 25 CU FT French Door Bottom Freezer with water dispenser inside. Recently the vegetables, milk and most foods have been freezing. The water reservoir at the back of the unit is frozen solid. Interior temp is set to 38 degreesF for the upper unit and 0 degreesF for freezer. We haven't changed the temp settings.

This is due to defrost not working in your unit.First Try the manual defrost reset procedure before replacing any part.------- 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, if the problem returns again. If the same problem occurs then it's defrost problem. The defrost board and the defrost thermostat/heater is not functioning properly and it has to be checked and replaced. ------------------------- to get required parts for your refrigerator you can get it from www.repairclinic.com .This should help.
