I usually put the probe in a glass of water in the brew fridge to stop temp reading fluctuating too quickly and stop cycling the fridge too much, but now it looks like the probe is corroding and it looks like the readings are way off. Set too 7c and there’s ice forming inside!
I assume the corrosion has damaged the probe?
Any similar experiences?
Also- if i replace, i wont put it in water again

Cheers
