Randal for Model Number Fftr1814qw1 The freezer freezes up and the refrigerator gets warm. I can't get it into service mode by following the instructions. Would this be the board?
Answer Randal, the first thing that you will want to check is the defrost heater, bi-metal, and thermistor. The defrost heater should test at 35 ohms, the defrost bi-metal should have continuity in temperatures less than 110 degrees Fahrenheit, and the defrost thermistor will vary in resistance based on its temperature. If the thermistor reads 19.37 kOhms, then it is sensing 47 degrees, 24.53 kOhms for 37 degrees, and 31.33 kOhms for 27 degrees. Once it has been verified that the heater and bi-metal are testing good, and that the thermistor is reading colder than 47 degrees, then the control would be the next step. Read More...
