TruSteam water sensor
A number of people have experienced failures with the water sensor in their TrueSteam humidifiers. I now belong to that group. Honeywell is pretty hostile to DIY people, so you might have to get an HVAC guy to come look at yours when it quits. Anyway, these sensors seem to fail pretty often. If yours is broken, Honeywell will send you 2 new ones, presumably because they know that the replacement is going to fail as well. And, they are now telling people that the sensor should just be replaced every year as a maintenance item. I don't know if they'll just keep sending free replacements, but I kind of doubt it. (It would be nice if they redesigned them so the plastic they're made of didn't crack and fail.) Plus, if you follow the rules, you'll have a $113 service call (what it cost me, anyway) to have some guy come and replace it for you. Kind of harsh to have to spend $160 (if you have to buy the sensor, too) every year for the life of the unit to keep it working, on top of the energy costs, and the $25 water filter that should be replaced every 6 or 12 months, depending on how hard your water is. Don't get me wrong - I like what the TrueSteam does, but it's not clear it's worth it. At a minimum, Honeywell ought to let you replace the sensor yourself, if you're so inclined. It's not really very hard to do, and takes about 10 minutes time.
