hello, I received a bosch kdn49, with the same problem, the busted triac and the cut environment sensor, the first thing I noticed, was the sensor, because the refrigerator was about 10 minutes and cut the compressor, change the sensor and started to establish normal periods and consequently a good cold, but I realized that, when returning from defrosting, the alarm was activated and when it reached temperatures of less than 12 or more, it went off, but it was rare for me to make that error, I uncovered the plate and I found the triac with a flash, which I don't know why replace it
