Buzzer/Timer for 2g Milk Pasteurizers SafGard KleenFlo

Pretty easy to install but the new buzzer works inconsistently. I found that out the hard way when I went to check on a batch of milk that was taking longer than normal. Milk was 180 degrees and a lot of water in the heat tank gone. I now use my phone to time every batch because I no longer trust the buzzer. The way the unit is set up, if the buzzer goes bad the unit won't work at all. So as long as the buzzer allows the pasteurizer to do its thing, I'm fine using my phone as a timer.
