LFC25760SB - Interior Lights Issue
« on: October 20, 2012, 04:51:01 PM »
I'm having an issue with the interior lights of my LG LFC25760SB, manufactured in 2006.  When the doors are opened, the interior lights do not come on.

We've tried a few things with no results:

While troubleshooting, I've noticed that if the door is open and I repeatedly depress the door switch, the interior lights will flicker, so they are getting some power, they just won't remain on.  I'm not sure what I should be looking for to further troubleshoot or what parts to replace, looking for some guidance from the community.

Hi, most likely a problem with the main control board.
I looked up your model and it uses control board part # 6871JB1423N

These have a problem with the light relay staying on and melting the light cover.  It sounds like you have the opposite problem. The fix is new cover and light sockets with a thermal fuse and a new control board with a larger light relay. Contact LG customer service, it should be a free repair.

That's right, i forgot to mention that we had that issue back in Sept 2011 where the light melted the cover.  We had that repaired for free by LG.  A year later, I now have the opposite problem as you pointed out.  I tried calling LG about it last month, they pointed me to a local tech who look at it and told me what I already know, the light's not working.

Thanks for the input, I'll look into the control board and will try LG again with the info in the thread you shared.

Sounds good, let us know what LG has to say.

Also here is the service manual for your model refrigerator. Maybe you will find it helpful.

**********************

Every single incident that I've encountered with the above-mentioned-symptoms---an LG authorized "technician" stated to the customer that the MAIN BOARD and LIGHTBULB ASSY (with  a thermostat) was replaced.

In each case---the MAIN BOARD had **NOT** been replaced.
Only the LIGHTBULB ASSY was replaced.

I don't understand, why would a tech tell a customer the board had been replaced when it was not?
"Depend on us."

Yes, I replaced the main control board to fix the issues with the lights.  Thanks to all for their input.
