Faulty LG F14A8RD temp button
Hi,
I have a faulty temp button on my LG washer dryer. I have taken the plastic cover off and had a look at the PCU. The button will work if u press it in fully but the touch aspect doesn't work, meaning it wont work through the plastic front panel. I have spoken to LG and they weren't very helpful. Looking at the button compared to the others, it looks as though the "tape" across the front is maybe water damaged, its a slightly different colour. I realise i can get a new PCU but they aren't cheap. Is it possible to repair the touch aspect of the button or replace this?
Thanks

LG F14A8RD temperature touch button faulty on control panel
- The problem
- On an LG F14A8RD washer dryer, the temperature button would only operate when pressed directly on the control board with the plastic front removed. Through the normal plastic fascia it would not respond to touch.
- Likely cause
- The discussion strongly suggests a failed touch-sensitive button area on the control panel/control board, possibly associated with visible damage or discolouration to the tape/overlay at the front of that button. Exact component failure was not confirmed.
- What fixed it
- Forum advice was that, because the faulty button is part of the control panel/PCB, separate parts were not available and a board-level repair was not identified. The practical option discussed was replacement of the complete control board/panel, but the original poster decided not to proceed due to cost and planned to look for a used part instead.
- Checks to try
- Plastic cover removed and button tested directly on the control board
- Compared faulty button with the other buttons
- Observed the tape/overlay on the faulty button looked a different colour and possibly water damaged
- Confirmed the button changes temperature only when pressed fully with the front cover removed
- Confirmed the issue is limited to the temperature button
- Parts or tools mentioned
- Control board/control panel
- Used replacement part

Hi. Do you mean the control panel? There won’t be any parts available for the PCB or control panel if the button is part of the control panel board. That’s the problem, no parts no repair. Apart from trying some wd-40 on it I can’t suggest anything.

Hi,
Thanks for your reply.
The button is part of the control board and its touch sensitive, which is the bit which doesn't work anymore. The tape across the front of the button which must give it its touch feature looks damaged. I hadn't seen any spare parts but thought i would ask. The button will push in and will change the temp but only when the plastic front cover is removed. The front cover doesn't allow for the button to be pressed inwards as its solid plastic and works off touch. The cost of a new board to around £140 and i didn't really want to be forking out that much.
Those little built in push buttons can definitely go faulty so they don't work properly. It's ludicrous that it costs so much for a printed circuit board. I would assume that hopefully you can still use the machine, it wouldn't be worth spending that much on it.

Thanks for your help.
Luckily it still can be used as its just the temp button and not any other.
The cost of a board is stupid and they are very hard to find, so theres no offers anywhere.
Ill keep a look out for a used part on ebay.
Thanks again
