When I bought my first house 22 years ago lol my mom bought my refrigerator. It's an Amana and would still be kicking butt if a spring mount in the compressor didn't come loose. The motor rides on 3 or 4 springs in there, I can't remember, but if one comes loose or breaks, when the motor in the compressor stops it's cycle, the down torqueing makes it wobble so you will hear a loud Clank, bang, thunk. I mean it will scare anybody if they're not use to it. It's been doing that for at least 5 years, still working though. I checked out youtube and refrigerator compressors for a while when I was playing around with the one I found. Apparently, compressors from China were causing some problems but I think China is doing better with it's manufacturing today. It's hard to get over it though, when you read, "made in China" on the back, I know, the "oh no" trigger goes off in the brain. I just found this

We have several appliance repair and resale stores like that around here. Most have been around a while, they seem to do good business.
There's a biz a few miles north of me that does just that, I think it's just one guy that owns and runs it. I bet he's making pretty good $ This stuff is usually easy to fix. When I bought that little dump of a house, it had a washer in there that didn't work. Somebody bought a new timer for it thinking that was the problem, it was sitting on the lid. I never tried fixing a washer before. That meant I was going to take it apart because I'm curious. There really isn't much to those things. I saw the door switch looked a little burned. That's all the problem was, the switch, only cost about $20. I think those guys go pick up this stuff, look on CL under "free stuff", bring it to the shop, spend $50 or so on it and sell it for $300-$400.
