jbradley0227 posted a topic in DIY Appliance Repair HelpI have a Kenmore French door / bottom freezer - Model 795.72053.110 that we purchased in June of 2011. This has a LG Linear Compressor. We just came back from vacation and discovered the refrigerator was running but not cooling anymore. Everything was defrosted. We found out that while we were away the power had gone out for a few hours and then come back on. The compressor is running but only slightly warm. Condenser and Circulating fans are running. Coils are not frozen and only get to about 40 degrees. I unplugged the frig for 1/2 hour last night and then plugged it back in. It ran all night and this morning it was still warm. The compressor is running constantly. I tested the resistance of the compressor and it reads between 6.8 and 7.1 ohms (one of the posts reads open but I think that's normal on a linear compressor). Is this a variable speed compressor? Could it be a circuit board problem due to the power outage or do you think this is an internal compressor or freon problem. I've read that these linear compressors are not reliable. According to my manual, the compressor is supposed to be under warranty for 10 years but NOBODY at Sears will verify that without me paying for technician to come out. I'm also afraid that even if I replace the compressor the system may be contaminated if there was an internal failure in the compressor. I watched a few videos of people tearing down these compressors and they seem to find that an internal valve goes bad and leaves behind a lot of metal shavings. I don't want to waste any money on this frig if it's not worth fixing. Thank you for any help.
New to the forum, tech with 4yrs experience just getting back into the field after 11 years in the military, so playing catch-up on new stuff. On LG refrigerators with the linear compressors with no cooling, I've been consistently reading anywhere between 600-1500 VAC on the CON201 terminals to the compressor, whether the connecter is hooked up or not. Several of my fellow techs have seen this as well. LG says the max VAC output to the comp should be ~180VAC. I've never had any issues with my Fieldpiece meter. Am I doing something wrong or is my meter insufficient for LGs?
