    Ausrufezeichen Temp sensor not working

    I have a profilux 3 that I upgraded from 2 when it first became available. Temp readings were very accurate up until 3 weeks ago. The temp probe all of a sudden registered 102.8 deg and I was lucky to catch it before I lost the tank. After a couple of restarts and resets - no change. So I bought a NEW temp probe and I just installed it. Same thing - 102.8!!!!!!!!!!!!! I don't understand what is the issue?! Is it the board?

    Thanks!

    If you gently push in and hold the temp plug into the port, do the temp readings go back to normal?

    Have you made any changes to the temp calibration data lately?

    Hi, we are happy to hear that you have a ProfiLux Plus II (upgraded to 3) which must be at least 6 years old and it is still working great besides this temp. issue.

    Maybe during the last couple years the electronics and/or the temp.-probe aged a bit. I think it is possible that the temp.-sensor is defective, maybe even the PII-board, maybe even caused by external circumstances.

    I think it is worth to try a new probe.
