Russell Dunn February 08, 2022 for Model Number 795.74043.411 Hello, My unit was made (per label) in March 2015. The fridge is not cooling at all (about room temp) and the freezer is 45 degrees. I've replaced the overload assembly, and the control board. There is no ice buildup behind the wall in the freezer section. There are no error codes on the display. The compressor hums with no clicks or rattles. There is a yellow DRY powder in the drip pan. All fans are running. Would someone please point me in a new direction? Thanks, Russ
1 Answer Russell, If the unit has frost on the rear wall then you will want to pull the rear wall and check for the coils being impacted with ice. It sounds like you have a defrost problem in which you will need to test the heater and the defrot sensor and thermal to make sure that they are good. If they are then the issue will be with the main control board. Read More...
Matt July 05, 2021 for Model Number LFX31925ST/04 There are to control assemblies. What is the difference? Refrigerator Control Assembly Part Number: AP5325101 Defrost Control Assembly Part Number: AP6004251 I have an Error code r DH whih leads me to the defrost assembly. Is there anohter assembly which would throw the same error? Should I get both just in case?
1 Answer Matt, It may not be the control board but the sensor for the defrost that is faulty. It would be recommended to test this sensor for resistance and the fuse for continuity. If the fuse does not have continuity then you would need to replace the assembly 6615JB2005R. If the resistance is off with the sensor then the assembly will need to be replaced. If both check ok then check the heater to make sure that it is good. If it is good then the main control board will be the issue.the only difference between the 2 parts is one is for the refrigerator and the other for the freezer. Read More...
Maurice November 22, 2020 for Model Number 79574023412 i have a kenmore elite model number 795.74023.412 i have replaced the capacitor the thermistor and the pcb board my problem is i cant get fridge to cool down all the way like it should its about 7 degrees off it wont hold temp it goes up and down fridge and freezer are doing the same thing fridge about 45 and freezer at about 5 degrees it acts to me like it dont come on when it should but when it does it cools off pretty quick to around 40 i cant get it down to 33 or any colder then 40 seems like when the door is opened it triggers fridge to cool i think maybe it gets stuck in defrost mode any ideas on which way to direct me would be greatly appreciated
1 Answer Hello Maurice, based on your description of the symptoms and the parts you have replaced (the main control board ) it is likely this point to be a compressor or sealed system problem. Read More...
Pavel September 07, 2020 for Model Number Kenmore 795.79993510 Both the fridge and freezer are not cooling enough. I opened the back of the freezer and found ice on the Evaporator Assembly. I thought that the problem may be in the Defrost Control Assembly, but the compressor is running non-stop and it is very hot (my understanding is that it should be off during the defrost cycle). I checked the Defrost Control Assembly (0 ohm on red, 14.5k ohms on orange) and both Heaters around the Evaporator Assembly (66 and 155 ohms). How can I diagnose what is the issue here? Is the culprit the main control board? Thank you.
1 Answer Hello Pavel, the compressor is controlled by an inverter circuit, it and the defrost circuit are part of the main control board. This ref has dual evap coils, a defrost problem on one will not affect the other. Likely the ref is running a lot to try to cool each compartment to the correct set temp. This sounds like a sealed system problem rather than a control board problem. Read More...
Stan February 28, 2020 for Model Number LFX33975ST/03 Hello. I need some help to find the problem I have water in the fridge part of my LG Fridge.LFX33975ST/03 I opened the back panel inside the fridge and there was ice at the bottom of the tray. the drain pipe was frozen.water was going inside. Should I try to change the defrost control module#AP6004251 red wire sensor is reading 0hms the orange11.7kohms Is this O.K Or there is something else. The heater element has 82ohms I have already cleaned the pipe a month ago. But the problem is coming back. Thank you for your help. Stan
1 Answer Stan, as the drain hole is clogged up, it is likely that the drain tube 5251JA2006B at the compressor section is sticking closed and would need to be replaced. Read More...
Joe W. July 05, 2019 for Model Number LFXS30726S I'm losing my mind trying to figure out why my LG french door refrigerator isn't getting cold enough. The freezer isn't either. Initially, I opening up the bottom rear panel and vacuumed out the condenser coils and vent louver. They were covered in very thick dust and dirt. The condenser fan was working when the compressor was running. I let it run overnight but it is still not cold enough. I decided to replace the evaporator fan in the freezer. I checked continuity of the old one and noticed it only had continuity while I manually turned the motor shaft so I figured that should be the problem. It still doesn't seem to be getting to the proper temperature. Should I replace the temperature sensor in the freezer? Does that second evaporator fan push just push air up into the door for the ice maker? When I replaced the motor there was a fine even layer of frost across the entire evaporator coil so I didn't think there were any issues there. I'll let it run overnight but I'm losing hope.
1 Answer Hello Joe, If you could post a new question and include an e-mail address we can send you the troubleshooting section of the service guide to aid you in your repair. Read More...
Frankie B March 12, 2019 for Model Number LFXS30766S/00 Unit not cooling, compressor is pumping but no air coming from duct from evap. fan what should I be looking for to get this unit cooling? These newer refrigerators can be very challenging for me as I am from the 60's and am use to the older simple to repair ones. Any help would be very appreciated. Thanks, Frankie
1 Answer Frankie, The first step in figuring this unit out would be to remove the rear wall and check to make sure that there is a frost pattern on the evaporator coils. The fan does not run when the doors are open. If there is ice completely covering and blocking air flow then this would be a defrost issue in which you would need to test the evaporator sensor, defrost heater and if they are ok then will be a faulty control board. If there is no frost pattern at all then this would be a sealed system issue in which you would need to have service to repair. If the frost pattern is full even frost pattern top to bottom then this would be a normal frost pattern and would need to test to see if the control board is sending power to the fan to run. If it is then replace the fan if it does not run. Read More...
Eric L July 18, 2017 for Model Number LFX31945ST/02 Hello our fridge is not cooling, I've open up the bottom to see the coil had frozen in the freezer. Now that I found my problem I was wondering if it could be the fan part#[EAU60694510] reason why is that it's not consistently on. I have no clue if it should. Thanks for your time. Eric
1 Answer Eric, The coils in the freezer being frozen would be a issue with the defrost system. You will want to check the heater and the controller assembly to make sure they have continuity. If they check ok then the issue will be the main control board. The fan motor would most likely not be the issue with this unit. Read More...
Robert February 13, 2017 for Model Number lfxc24726S/00 My LG 3 door (freezer bottom) evaporator is frosting up about every 2 weeks. Last hairdryer defrost I noted more for information. The heater element was warm to touch (approx 1-2 sec touch) but maybe from the hairdryer? Looking at your site about issues it seemed the defrost sensor or thermostat might be the issue. Comments?
1 Answer Hello Robert. You will need to test the heater MEE62225112 and the sensor 6615JB2005S in the unit. If both test good, then you will need to replace the main control board. Usually in most cases it is the thermal fuse in the sensor assembly 6615JB2005S that fails. 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...
Ryan August 28, 2015 for Model Number 795.72053.112 Does this refrigerator have a thermistor in the freezer and fresh food section of the refrigerator? If so please let me know what part numbers I need.
1 Answer Hello Ryan, The freezer temperature sensor is part 6500JB2001B and the one in the fresh food compartment is ACQ73244001. Read More...
