Hi guys,

i’ve tried using the search function but nothing coming back under fh4g6tdn2.

I’ve got an LG fh4g6tdn2 front load with touch screen that wont power on the display. Now i’ve tried unplugging and holding play/pause and this resets but still doesn’t allow the front panel to light up. It does however bring the red supply light on on the back of the board which is telling me that supplyto there is in fact okay. After not getting a run command the board then switches off after about a minute.

The unit itself is in the out house so my first question is “do these have a trip for external low temp”? Secondly, does anyone have any ideas on what it could be?

Thanks in advance, any help really is appreciated!

Solution Summary

AI-generated from this discussion

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

LG FH4G6TDN2 washing machine dead with no display

The problem
LG FH4G6TDN2 front-loading washing machine would not power up the display. The user had already tried unplugging it and holding Play/Pause to reset it. A red supply light was seen on the rear board, then the board switched off after about a minute when no run command was received. The machine was located in an outbuilding and the user asked whether low temperature could inhibit operation.
Likely cause
The accepted reply said low temperature was not thought likely to trip a sensor in this case. The strongest supported diagnosis was a power supply problem, despite the rear board supply light being present.
What fixed it
Recommended actions were to first try the machine on a completely different socket, and otherwise suspect a power supply fault. No specific component replacement or completed repair was confirmed in the discussion.
Checks to try
  • Unplugged the machine and held Play/Pause to attempt a reset
  • Observed a red supply light on the back of the board
  • Noted the board switched off after about a minute without a run command
  • Advised to try a totally different socket

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi. I don’t think the temperature would trip any sensors. If by any chance they had designed it to do that it would most likely display an error code indicating the temperature was too low.

Usually if an appliance is totally dead with no display apart from lights you’d have to firstly suspect a power supply problem. Make sure you try a totally different socket just in case though that’s a long shot.
