Comments about Honeywell Honeywell 50027998-001 Water Level Sensor for TrueSTEAM Humidifiers:
Couldn't imagine this piece could go bad. Followed the troubleshooting diagnostic code in the manual, changed the part, and the unit worked. I am a plumber for a plumbing, electrical, and hvac company. Our service manager said that our hvac division changes these things everyday.
