Customer Questions and Answers for Refrigerator Main Control Board by Ge

Jeff, You will want to check the thermistors in the unit to make sure that they are reading the proper resistance. The following chart is the resistance values for the thermistors. Thermistor Resistance Temperature(°F)Temperature(°C)Resistance in Kilo-Ohms -40 -40 166.8 kO -31 -35 120.5 kO -22 -30 88.0 kO -13 -25 65.0 kO -4 -20 48.4 kO 5 -15 36.4 kO 14 -10 27.6 kO 23 -5 21.0 kO 32 0 16.3 kO 41 5 12.7 kO 50 10 10.0 kO 59 15 7.8 kO 68 20 6.2 kO 77 25 5.0 kO 86 30 4.0 kO 95 35 3.2 kO 104 40 2.6 kO 113 45 2.2 kO 122 50 1.8 kO 131 55 1.5 kO 140 60 1.2 kO Note: To accurately test a thermistor, place the thermistor in a glass of ice water (approximately 33°F) for several minutes and check for approximately 16K O. If the resistance is not within ranges listed then the thermistors would need to be replaced. If they check ok then the main control board would be the issue.
