High or low depending on the mode. If the frost pattern is good then test the thermistor which should have a resistance of 5K ohms at room temperature and if the sensor is good then it would be the control board that is causing this issue. Our example thermistor performance curve chart (left) is for an NTC thermistor as we will explain below. For copper cable with a cross-section of 0.22 mm2, the following guide value applies: 0.162 Ω/m → 0.42 °C/m for Pt100. $15.67. Yes; The capacitor fan runs constantly. Alternatively, a version with Pt1000 sensor can be chosen, with which the influence of the supply line (at 0.04 °C/m) is smaller by a factor of 10. Using your ohmmeter, read the resistance of the sensor to determine the temperature. The manufacturer typically determines this property with a high degree of accuracy, as this … Please note that the typical failure mode for this type of sensor is to cause the refrigerator to cool all of the time due to high resistance. The circuit board uses data sent from the thermistor to determine when it should cut power to the heating element and allow the drying cycle to restart. It’s possible for one to erroneously appear open circuit if you don’t have the range correctly set to high on a continuity test meter. Slight frost buildup near the door gasket but the gasket is tight with no gaps. LMX25984SW LMX28988ST LFX21976ST … positive E - PT1000A Sensor type: Platinum, temp coef.
