I have an older BM23. A few months ago it was having difficulty staying cold. I had a tech come out and recharge the coolant. That worked for about 3 months and it started acting up again. He came back out and replaced the evaporator coil (just before July 4th 2015). Said there was a small leak and this should really fix it. It seemed to be work well after that. I had the thermostat set around 5 and that seemed to be a good temperature. However, after getting a keg in there, it was actually colder than I thought and I nearly froze the keg. I ended up turning the thermostat to just under 3. That put the temp around 38F degrees. I just recently noticed that the tower was not cooling. After poking around this weekend, I realized that the tower hose wasn't getting any air because it was blocked by ice. I exposed the evaporator coil to find that it was encased in a block of ice! I took a hair dryer and melted all of the ice off and powered the unit back up. Thermostat set at 3 is giving me about 47 degrees, so I dialed it up to 4. Will check tonight to see what temp that gives me.
I've never had this issue before. What are the causes of a frozen evaporator coil? The fan in front of the coil (the same one that pushed air to the tower) seems to be working just fine.
Thanks for the help!
