Repairing Chest Freezer for Ferm Temp Ctrl
I bought a gigantic (maybe 20+ cu. ft. by the looks of it, but I don't know), 16 yr old chest freezer from craigslist.
Kenmore Model 253.9133580
The freezer's plugged into an analog temperature controller (the cheap one from morebeer) that is set to maintain the temperature inside at 65 F.
I have only brewed a Mr. Beer 2 gal kit. I was about to have my first real brew day when my chest freezer stopped working. I have very basic knowledge of fridge operation (from reading, not experience).
The first night I hooked it up, it sounded fine. The temperature warning light was flashing. I pressed it, but nothing happened. The freezer was producing a very loud, steady hum, so I was sure it was doing something. But when I checked on it the next day, there was an alarm sounding from the freezer. The temperature warning light was flashing as before. No signs of cooling. I still heard something running in the freezer, but it's very quiet compared to before. Maybe a major component like the compressor has failed.
I ran the freezer without the analog temp ctrl but the problem is the same.
I want to educate myself and try to make a good diagnosis. I want to be able to decide if I can fix it myself, hire a mechanic, or just find some other temp ctrl. Please point me in the right direction guys. Thanks!
