George My samsung mod# LMX25964ST is only keeping the fridge and freezer compt. at about 45-50f. Took it apart and measured freezer sensor at 3.2k ohms. Measured sensor in defrost evap coil area at 15k. Both at room temp, defrost might have been a bit cooler air temp. with fridge off for a wile and testing while still on unit. Do you think the thermistor sensors are bad or just one? Thanks.
Answer George, The sensors sound like it may be correct except the defrost sensor is high on resistance. You would want to check to make sure that the evaporator coils in the freezer have a full even frost pattern so you will want to turn the unit on and let it run for 24 hours then check the coils. If they do not have a full even frost pattern then this will be a sealed system issue and will need service. Read More... Answered by AppliancePartsPros.com | Monday, February 4, 2019
