Donald April 11, 2019 for Model Number LRBC20512WW How can I run diagnostic mode? All temperatures are fine in frig/freezer, and the display board is not working. If you unplug it, it will work for a time then only the right side shows, and then only 456 on display will light up, but both freezer/frig work.
1 Answer Donald, you will want to check the voltage going to the dispenser board. The display board should receive constant voltage and if it does receive constant voltage during a state of failure, then the display board [6871JB2047A] is bad. If the display does not receive a constant voltage supply, then the main control [6871JB1215J] is the issue. Read More...
Basil March 26, 2016 for Model Number kenmore fridge mod# 795.75012402 I had a low voltage problem in my neighborhood and just after that my refrigerator temperature control selector which is the left side is the fridge and the right side is freezer. The setting are 1 thru 7 on either side. So I notice that freezer side stay lite up on 5 6 7, and the fridge side is not lite up. And i'm not able to make any adjustment or change the setting on the side that's lite up which is the freezer. So i unplug the refrigerator for 5 minutes and plug it back in, and it started back working like it normally use to. Both sides lite up and I can adjust the temp setting as I would like on either side. But this will only work or stay like this until it makes a few cycles on and off, and then it goes back to the freezer setting only 567, and stays like that. The refrigerator is cooling top & bottom and cycling off as it normally does. Could I have a bad control board due to the low voltage problem that I had? It's a Kenmore refrigerator, the fridge compartment is at the top & the freezer is at the bottom, mod#795.75012402.
1 Answer Basil, Yes this issue would most likely be caused by a faulty main control board 6871JB1215J. Read More...
Steve A March 17, 2015 for Model Number 795.75012402 Most times the food is thawed in the freezer section and the refrigerator is fine. Sometimes the food is frozen. Was told the defrost is cycling too often and a new control board is necessary. Any thoughts? Thank you
1 Answer Steve, Based on the description of the issue, it does sound like this could be the case with the unit. You will want to check to see if you notice the unit running at the time that it is warming up in the freezer. If it is not then unplug the unit and plug it back up and see if it come right on. If it does then the control board would be the issue. Read More...
Saruni February 04, 2015 1-power not coming out of control board,compressor not running 2-fridge not defrosting ice
1 Answer Hello Saruni. If the main board is not powering the compressor, and the defrost is not working, you will need to order and replace the main board on the unit. Read More...
Tom July 08, 2014 for Model Number LRDN22711TT Compressor runs fine, freezer freezes fine, refrigerator warm. Evaporator fan not blowing. Fan works fine on the bench. No voltage at the fan connector inside freezer. Do I need a new PCB assembly? My part # is 6871JB1215A, which appears to have been replaced by 6871JB1215J. If this doesn't fix the problem, is it returnable? Thanks for any help you can provide.
1 Answer Hello Tom. If there is no power coming from the control board to the fan motor, you will need to order and replace the main board on the unit. If it does not fix the issue, you can return the new board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Allen E December 04, 2013 for Model Number Kenmore 795.75002402 My refrigerator freezes everything. The push button control does not change when I select a different setting. What part do I need to fix this?
1 Answer Allen, There is a damper in the duct assembly that sounds like it is stuck open and would be causing the freezing issue. If the door is broken or stuck then the duct assembly [AP4439530 would need to be replaced. Read More...
Rich September 03, 2013 for Model Number LRBC22522ST LG LRBC22522ST Fridge not cold but the freezer works fine. Temp controls work and I can adjust for both but not happens in the fridge. If I hold the door button closed I feel no air coming out. Pulled off the back cover in the freezer compartment and did not see the fan spinning. Tested the wiring harness and their is no voltage going to the fan.
1 Answer Hello Rich. Test it with the door switch taped shut. If no voltage, replace the main board in the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
James June 22, 2013 for Model Number LRBC20512WW I submitted a question before about a month ago about this LG bottom freezer and had some more info to help diagnose problem. top fridge is 38-40 degrees bottom freezer 20-30 degrees. No ice on coils, fans working, and it comes on and cycles . freezer just won't freeze anything. Thank you,
1 Answer James, You will want to check the evaporator for a full complete and even frost pattern. If there is very little frost on the coils then the issue would be a sealed system leak. If there is no frost pattern then it is either a compressor, leak or restriction in the sealed system. Read More...
Ray December 31, 2012 for Model Number LRBN22514st Ice cream and other foods are not cold enough. Bought freezer thermometer and temp was in the upper 20’s F. Actions: Cleaned condenser coils – no change in temperature. Removed freezer cover panel and inspected evaporator (no frost). Unplugged defrost thermostat and defrost heater element and operated refrigerator – Freezer temperatures dropped to low-mid teens. Ordered replacement defrost thermostat. Installed new defrost thermostat and plugged in heater element. After 48 hours the freezer temperature is at 23°F and the refrigerator temp is at 37°F. What else I should try before calling a serviceman or buying a new refrigerator? Thanks
1 Answer Hello Ray, If there was no frost pattern on the evaporator, the issue is definitely not related to the defrost circuit. I'm curious as to whether there was any ice at the back wall where the freon line enters the freezer compartment. This would be an indication of a freon loss. If there was no ice at all and the temperature dropped to 32°F, I would be more inclined to suspect a bad relay on the control board. This would cause the unit to operate normally at times and not operate normally when the relay didn't make electrical connection. 37°F is a perfect temperature for the fresh food compartment, but 23 is at least 8° too warm for the freezer compartment. I believe the most likely suspect in the electrical control circuit would be an out-of-tolerance temperature sensor 6500JB2002T in the freezer compartment. The last thing to try, (because of cost), would be the control board 6871JB1215J. Read More...
Larry August 25, 2011 for Model Number 795.75014402 The frig will run 6-8 hours and then the settings go crazy. The only way to reset it is to unplug and plug it back in. It never will go into defrost. I replaced the mother board and that did not solve the problem. Do you have any suggestions for how to fix this?
1 Answer Hello Larry. Based on the information you provided, it sounds like the case assembly ABQ33905301 my be bad on the unit. If you have replace the main PCB assembly 6871JB1215J, and the problem continues, you will need to replace the case assembly. Hope this helps. Read More...
