The problem is that the humidifier heater bar needs replacing. At least that is what I found with the three that had that problem for me. Luckily, they wee still under warranty. The fix so that it doesn't happen in the first place is to make sure to use the plastic sleeve, over the heater rod, to stop it corroding.

Greetings, Just wondering if others are having problems with the D.C. Humidistate and the red light going on with no smart bar installed. I've just had my third one with this problem. Just before, or with 2 of them just after the 5 year warranty runs out. I've had the old ones, 25 + years old and still working fine. Had nothing but problems with the early smart bars and now the humidistates. Would like to hear from you if you are starting to have this problem. Ron Lindquist
