LG GR-L206CPQA fridge freezer repair.

I'm sat in the lounge watching the news....

Ding-dong. Ding-dong. Ding-dong. Ding-dong.

Funny... that's the noise our fridge makes when someone pushes a button on the front panel.

I walk into the kitchen... it stops...

It appears our fridge is possessed (possibly by the curry I stuck in it's freezer compartment last night)

Ding-dong. Nope, it's altering it's fridge temperature settings on it's own...

I'll take a look before organising a priest....



It's an LG of some vintage. It wasn't new when we got it... ah, found the logo under some of the fridge magnets...




















Let's get the front panel off... Grasp the panel and gently pull it off...












Unplug the PCB and retire to the workshop with the front...












The PCB is secured to the front panel with two philips screws...










... and removed shows the three tactile switches. One for freezer temp, one for fridge temp, and one switches the ice making thing into different modes.

Sure enough the fridge temp switch reads leaky, at about 40 kilohms. Checking the others show them to be better, but still a bit leaky at ~200 kilohms.




Sadly, I'm out of stock of suitable switches, so I order some. In the meantime, I give the switches a good dose of switch cleaner, which seems to fix it (at least temporarily, whilst the replacement switches arrive)

Another (and probably damned expensive thing to replace) saved from consignment to an expensive de-gassing and recycling scheme, if not landfill.

  1. So glad you posted this as I’ve been having the same problem and it’s been driving me mad. I’ve taken the front off and weirdly enough it’s stopped. Do I have to switch the appliance off to unplug the PCB?

    1. I didn't. But just in case your supply isn't isolated, it may be prudent..

  2. Hi mate, just wondering a couple of things.
    1. Were the switches easy to solder ?
    2. What exact switches were they
    3. How did you get the panel off as ours is pretty stiff
    4.did the fix work in the end ?

    1. 1. Yes it' really straight forward through-hole construction.
      2. A quick search on eBay should find you the exact replacement. Beware you want to get the correct shaft-length.
      3. Yeah, it's stiff. Perhaps work round the outside with one of those plastic spudgers used to crack open mobile phones.
      4. Still working now!

  3. The size is 6x6x5mm
