Samurai Appliance Repair Man posted a blog entry in Samurai Appliance Repair Man's BlogThis LG refrigerator was DOA- warm inside, no compressor operation, no lights, no nuttin'. Found a blown fuse on the main control board. What took out the fuse: bad board or just a spike on the power line? I show how to check for that. The fuses on these LG boards are soldered in and not easily replaceable. But a new fuse can be installed and I show how to do that without even having to remove the board, while it's still installed in the refrigerator.

15yr old ge profile refrigerator. Noticed freezer contents like ice cream softer than usual suddenly. Condenser fan appears to be running slower than I would expect to keep it cool. Metered voltage at J2 T3&5 is 4.35 which I understand should be in the 12/8/4v range depending on if it is a variable voltage compressor which I believe it is based on what I think is the invertor to the compressor. J2 Pin 3&8 give 13.38v within the 12-14 proper range. Placed a fan behind which seems to help get it cooler inside. Temperature in freezer doesn't seem to want to get below 5F with fridge
