Question about LG Refrigerators
Model number LMX25981ST. Rest on main board does not fix problem.
My name is Peter. I am a retired field service refrigeration technician.
In your owners manual, it is recommended that you have a surge protector on your unit. In fact, any appliance including your television, home computer requires a surge protector.
At your local Home Depot, Ect. you can purchase individual wall socket surge protectors for about $20.00. They are a well worth investment.
Your board reset button is not going to work. The power shut down and restarting surge blew out both your control board and control board capacitor.
As a field service refrigeration technician, I carried no less than 3 LG control boards in my truck. 65% of my service calls were LG & Samsung. The fewest service calls I had were Amanda & Kitchen Aid, follower by GE and Kenmore.
Anyway, You need to replace both the control board (Part Number LMX25981ST - $122.00) and your control board capacitor (Part Number OCZJB20146 - $27.00).
You can get a lower price searching on the internet.
You have already accessed your control board.
So, lets replace the control board and capacitor.
1.) Un plug your unit.
2.) First ground yourself, static electricity will nock out your board. Rub your hands across something that is steel. Do not wear wool clothing.
3.) Your new control board will come in a anti-static silver bag.
4.) The control board is held in by several white pins. On the two sides of these pins are clips you must squeeze in to pull the board out.
5.) Systematically, remove one connector from the old board to the new board. The connectors have a locking tab at the top, squeeze the tab to remove. When inserting on the new board make sure these clips are locked in.
6.) replace the capacitor next to the board.
7.) Reattach the control board cover plate. Plug your unit back in. Allow 24 hours or less for the unit to balance the high pressure (160 PSI) liquid and the low side (65 PSI) vapor side.

Testimonial: "Peter, thank you for your response and I will be following your instructions. You sent me the Model number rather than the part number for the board. Do you have the part number for the control board?"

Ok the motherboard is malfunctioning. Ive observed this exact problem before. Replace the board and all will be normal again. If you keep lettig it click and click it may finally kill that relay that you descibed to me or even worse the compressor itself.

The compressor is locked up. Basically it is stuck. You can pick up at the local appliance parts store a hard start relay, Home Depot ,Lowes, or or those guys wont have it. Its not too expensive and is worth trying because your only other option is you need to replace the compressor. The part is called a kick start or hard start, the guy at the parts store will know what you are talking about. It is simple to connect and has the wiring directions on it. Sometimes this is all it takes. I have been able to get a stuck compressor to go by placing a short 2x4 on it and whack it with a hammer a few times. This is only a temporary fix though, as it will eventually lock up again, but emergency situation this saved the food. If the fridge has a fan back there make sure it works too, it may have been the original cause. Good luck.

The ice remains stuck between the dispenser and the top of feeding ice. This respond to a broke rubber on the last section where the ice must be delivered. Replace the rubber will fixed the problem. It is a common problem on this kind of devices. To remove the ice simply move the stuck ice from the bottom oro yu can try putting some warm water from the top. Before to do nothing, unplugg your refrigerator first.

It is possible you have a defective fan motor in the condenser area or evaporator area. Sometimes when they become defective they will run for a while and just warm up and stop while the compressor continues to run. I learned that one on four costly returns to the home. The cost was to me not the customer. Thanks, Sea Breeze
