One of my Johnson (blue) digital temp controllers seems to be acting a bit wonky as of today. I have it set for 57F to cool down to 55F. It just keeps flashing between ASD cycle and 57F reading. If it bump the temp up one degree the flashing stops but then the temps blink back and forth between 55F and 57F. WTF?
Granted, I do brew a lot of beer and this controller has seen a ton of fermentations, but does anyone have any data points on how long one of these things last?
I am not 100% sure of how old it is, but I have owned at least 7 of these in my brewing days and never seen anything like this before. Just wondering if the controller itself might be going south. Thoughts from the crew?
set the ASD to 0 minutes then set your temp but then go back after that make your fridge turn on…Then readjust it back to whatever time you want your compressor to cycle/ minutes.
I accidently turned mine off the other day and that fixes it…
But I will try this if it persists. Last night I swapped it out with another digital temp controller I have on my serving chest freezer. The wonky one got right to work no problem and last night the chest freezer one I put on my fermentation fridge also started working better.
Today when I get home from work, the display is reading 55F and then the fridge turned on? WTF? It should only turn on at 57F. Oh well, at least the beer is being cooled. Weird though.
I may try that trick above.
