Spec table for the GE-built refrigerators using the WR55X10025 thermistors. – Place the sensor in a glass of ice water. With the thermistor in a cup of water, the ohm reading should be around 16.6 K … Almost gone. This is taken as the R25 value, or the value at the temperature for which the resistance is given. The temperature sensor for the refrigerator section will be 30K at 32 F and approximately 5K at room temp of 70 F. The sensor and thermistor should be the same reading for the refrigerator compartment. The drain hole will be under the coils possibly covered with ice. my refrigerator lg model lfc25776st/03 is not cooling at all, compressor is running , condenser fan motor is working, LG Lfx31925st thermistor values are 5k at room temp and 15 k at 5 degrees Fahrenheit. For the freezer sensor ACQ73244001, the resistance would be 2.5kO at 77°F and 7.8kO at 32°F. The old way was with a mechanical thermometer with a capillary tube. Repair your LG Refrigerator Sensor & Thermistor for less. If there is not a frost pattern, with the compressor operating it would indicate a sealed system issue. ... AED74732910 LG Handle Assembly,refrigerator OEM AED74732910. If you purchase a random thermistor part, it might not match up with the model of your refrigerator and then the refrigerator won't operate correctly. The thermistor reading should be around 5K at room temperature and there is a fuse next to the filter that should have continuity. It tells the refrigerator when to turn on and when to turn off, based on the interior temperature within the refrigerator compartment. thermistor; ge; refrigerator; By Samurai Appliance Repair Man February 3, 2017; 17,239 views; View Samurai Appliance Repair Man's images; Share Followers 2.

Could you hear or feel the air movement from the evaporator fan motor [ADJ73252246] Refrigerator fresh food evaporator cover and fan(tape the door switch down). The idea behind these newfangled sensors is that their resistance increases as temperature decreases. The freezer evaporator does not defrost. I'm getting 2.54KOhm Room Temperature and 6.57KOhm at 32F (Sensor in ice water) on the Freezer sensor, not sure if this is correct or it should be replaced. Is the problem likely a bad sensor in the freezer section, a bad controller board, or a bad compressor or compressor charge? Most of the time the water is building up because the defrost drain line is clogged. There is no excessive frosting on the evap coil that I can see without pulling the panel, and I don't see any sign of a leak near the compressor (oil), and the condenser coils are clean and the fan is running. The thermistor reading should be around 5K at room temperature and there is a fuse next to the filter that should have continuity. Refrigerator not cooling but icemaker and freezer okay. Core Values Locations Rave Reviews Affiliates Program Job Listings Our Policies Ahh, those were the days. WP12791416 Whirlpool Thermistor OEM 12791416.

If this is the case, an EPA certified individual would be necessary to identify what has failed in the sealed system. Condensor coils must be clean as well. I use a garden sprayer with hot water to pump out and spray down the tube till its clear after i have removed any ice build up. Answer Edwin, as the defrost sensor assembly ACM73919214 has been replaced, it would be recommended that the defrost heater MEE62225101 is tested for resistance. The freezer is below zero. All rights reserved. Answer TK, Answer Rudy, it would be recommended that the evaporator is inspected to identify if there is a frost pattern. Thanks :) kenmore refrigerator model 79571019011 Answer Tim, We are Safe, Secure, Dependable and Trusted. ... New Genuine OEM LG Refrigerator Temperature Sensor 6500JB2001B. During the defrost cycle in a LG refrigerator model LFX21976ST, the defrost sensor tells the main control board the temperature inside the freezer.When the sensor is defective, the defrost cycle may stop functioning, which ultimately causes the evaporator in the freezer to ice up and the temperature in the fresh food compartment to increase. Icing Sensor will be the same as the freezer sensor. Refrigerator Thermistor Sensor for Whirlpool W10316760 AP4538142 PS2580944. Manny, at 77°F the resistance would be 11kO and at 32°F, the resistance would be 30KO for the refrigerator sensor. Values of ±2%, ±3% and ±5% are normally available. LG refrigerators come with a host of innovative features that complement a range of lifestyles and kitchen configurations. Thanks. thanks getting on nerves. Both freezer and refrigerator on the LG is not cooling. This site uses Akismet to reduce spam. $34.95. Learn how to test the thermistor to see if it's working. The control board will control each defrost circuit differently. Please help. REVIEW LG Electronics 70UF7700 70-Inch TV with BP350 Blu-Ray Player42 in lg tv | led 32 lg price | lg led lcd The sensor resistance should be 16 ohms ±5% at 32℉. Don't forget the condenser fan in the back needs to be running also whenever the compressor is running. I have a 3 door LG and the refrigerator section is staying between 45° and 52°F. If you’re starting from a temperature higher than 32℉, then you should see the sensor resistance increase; if the starting temperature was lower than 32℉, then you should see the sensor resistance decrease. Free shipping for many products! Almost gone. These sensors are also called thermistors. You’re looking for readings in the k-ohms range. The defrost heater should measure between 41O to 46O. I am not sure what part I would need to replace to troubleshoot this. The valve or other repairs would be a sealed system issue and would require a certified refrigerant repair technician to perform any repairs. Answer John, you'll need to access and check the main control board EBR83806901/EBR83806901 Refrigerator electronic control board for cracks, damage loose connections, and discolored/burnt areas on the board and components. The evaporator coil did not have any ice on them and did notice no air flow through refrigerator what is the problem. John, was there an even frost pattern across the evaporator top to bottom and front to back? I use an infrared temperature sensing gun for this. I am having a problem where there is water building up at the bottom of the inside of my fridge (freezer area is fine). Thermistors are specialized resistors whose resistance values change in accordance to the temperature they are exposed to. Note the resistance. I have decided to replace the thermistor, but … Then wait for at least five minutes for the temperature of the thermistor to reach 32 degrees. refri works proper defrost and stays at assigned temp (defrost perfectly) i know that refri works on a different cycle than freezer.
