This, things are simply not designed to be repaired, and the cost of repair often approaches the cost of replacement.
Years ago I had a LG fridge, bought it in 2008. A few years later I opened the door to it one morning and there were no lights on in the fridge. I noticed it also was not running.
Checked the breaker, it was on.
I thought great now what.
I pulled the fridge out and checked for power at the outlet yup got power.
Now I know its the fridge.
Pulled off that back cover that says do not remove, theres the circuit board and a automotive type glass fuse. Fuse is blown. Only thing is the fuse is soldered to the board, none removable.
I look online and a new board is $300.
So I get to looking at the board and came up with a idea.
How about I cut the fuse off, solder on fuse brackets and install a new fuse. If it works I saved $300 and have a removeable fuse, if it fails well I spend $300 or more if I want a new fridge.
Off I head to HD, pick up some fuses and fuse brackets, head home.
Cut off the fuse, leaving 2 small studs sticking up from the circuit board. Solder on the brackets, pop in a fuse, plug in fuse and Hey what do you know fridge is running.
A couple $$$ in parts, a little know how and a idea and $300 or more saved.
Fridge ran until December 2021 when the compressor finally crashed, bought a cheap GE top freezer for $600 at HD and its still up and running.
