Water sensor kit 50027998-002 for all TrueSteam models. Replaces part number 50027998-001. Includes the sensor, wire harness, 2 gaskets, retaining clip and screw. As shown in photo.
This sensor has five 1/4" terminals that connect with the harness's modular connector. The terminals are non-magnetic stainless steel bars that protrude out the bottom of the assembly at different levels.
This is a simple device with no internal electronics. Continuity should exist between the terminal connection and where the stainless steel protrudes from the bottom. Continuity should not exist between the different terminals (when dry).

TrueSTEAM Water Level Sensor: works fine

The original equipment sensor (part no. 50027998-001 in a Honeywell TrueSTEAM Direct-Injection Humidifier HM509A) failed after 3 years, due to cracks in the plastic coating around the metal probes. The troubleshooting procedure in the manual correctly identified the problem (2 blinks of red light = failed water sensor). After ordering the part, while waiting for it to arrive, I coated the cracks in the original sensor with superglue, which worked for a couple of days before it failed again.This replacement part was the correct item as advertised, and I receive it within the stated delivery time. Installation was simple, with instructions provided in the box in case the original manual is not available.In addition to the sensor and gaskets, a wiring connector and 2 wire clips were provided. I used the new gaskets, although the original ones were still pliable. I did not need the new wiring connector and I think it's unlikely this would fail within the service life of the humidifier. Only 1 wire clip is used, so even in the unlikely event that the original clip was damaged, including a 2nd clip is unnecessary.I installed the new sensor about 3 weeks ago and it is working properly. No way to know what its life span will be.

Shipping and brokerage fees to Canada added about $40 to the price of this Honeywell steam humidifier water level sensor. To replace it under warranty (part only), the local HVAC serviceman required ten times that amount and two service calls for which I would have had to hang around for a half day each. I would have had to wait 3 days because the part wasn't in stock at the HVAC depot. If I picked it up myself I would have had to pay for it (no warranty so at a much higher price than I paid from Pex), take a half day of my time and put 80 km/50 miles on the car.I ordered it online from Pex and the sensor (Honeywell original part) was delivered by UPS to my door in 7 days. It took me 5 minutes to install. Think I'm going to use my local HVAC dealer again? Not likely. We have extremely hard water and during the winter the steam humidifier requires monthly service with a complete cleaning each time. It does a superb job of humidifying and I'm happy with it even though it requires regular frequent and intensive maintenance.I would recommend a steam humidifier to a friend but with the reservation that the humidifier isn't install-and-forget.

When buying a new humidifier is NOT an alternative, Supply House came through again for me with affordable replacement parts for the Honeywell TrueSteam humidifier.
Exactly what the Stat ordered.

For some reason these fail, and this is what the stat tells you you need. Easy to replace and fixed the problem.

Ordered the part and fixed my humidifier that was overflowing from water source, existing part was clearly damaged (cracked at different dip sensors).

The sensor came on time, easy to install--except the screw was not easy to start ( a bit larger than hole).

HM512 Water Level Sensor Assembly...
from Salt Lake City, UT
Was getting a 6-flash error code on my Honeywell HM512 (water overflow alarm.) So I ordered a new sensor kit and installed it yesterday. Works like a charm (old unit came out easily, and the complete new unit went in just fine.) Seems to be working perfectly!But as I was putting back together, I noticed the top steam nozzle had broken in two...so now I'm checking on a new 50028000-001 remote nozzle/hose kit. So, if it ain't one thing, its amother!

Needed a replacement water level sensor for my Honeywell Steam Humidifier unit. Part was reasonably price, arrived quickly and was easy to install. Humidifier working like a charm now.
Trusteam humidifier water level sensor
from Burlington, KY
I have needed to replace this item every heating season since I purchased the TruSteam humidifier. The humidifiers are 3 years old and the parts are covered by warranty but it is still a hassle to replace it every season. Trusteam needs to correct whatever causes this item to fail.
