Newly purchased and set up per inst. worked great for two weeks while testing it out,checked it every day. Now 3 days before brewing my first lager I discover it no longer works. Display blinks 67 degrees ( so it gets ac) but does not allow AC to pass through to fridge any longer. It was set and maintaining 53, +/- 4 F. Took it out of line and fridge works fine, compressor ok. Tried leaving it unplugged…maybe to reset?..still just blinks temp.
Any thoughts? And yes I’ve already read all the negatives!
