Only two wires and two screws. Shut off the furnace disconnect switch before doing anything. Then Pull off the cover and I do mean pull off. Then undo the two screws remembering what terminal they go to. Remove the screws from the back plate and let the wires fall through the back plate as you pull it off the wall or duct. Put the new back plate in place with the wires pulled thought. Install the screws I the same place as the old ones. Re attach the wires into the same labeled terminals as the old one. Put the new cover on. Turn on the furnace disconnect switch and away you go. To check operation all you need to do is, turn the knob on the humidifier control and listen for the solenoid to open and water to flow to the humidifier. If nothing happens then you need to check for power to the humidistat. Should be 24v. If no power then you need to check the source.


good luck

, My KM30 Dehumidifier t'stat will not reognise ambient humidity properly. I placed the unit in my boat-steamy 80% humidity at 50%. it consistently turned itself off. Ok on 35 and Lo.


there is a sensor in the unit much like a temp sensor, (bullet shape) over time these do ware out and need to be replaced this tell the unit the temp so the unit knows humidity. it could also just need cleaning as a build up of damp then dry dust can cover the sensor.

I have a Lasko 1050. The sensor on my humidifier isn't sensing the humidity level correctly; how do I reset it, please? Thanks!


im in the suspicion that since you turned it upside down , some or possibly a lot of stored up water has gotten into the sensor section now , this might take several days of it running in what to remove and dry it all out , or might never recover as it's not a good idea to turn any item containing a gas compressor up side down , as this forces lube oils into the wrong places inside them
for the most part humidity sensors are not consumer (resettable)

Humidity sensor


It may be right. Are you sure you need dehumidification?

Put a free-standing humidity meter near the unit to check.

If you still want to run the dehum, take the humidity sensor out of the line and control the unit with a timer.

My Danby DDR583R dehumidifier no longer dehumidifies unless I set the humidistat to the lowest, constant run setting--then the compressor kicks on. The humidity reading says 14% which I know to be...


There are a several things that can mimic a faulty humidity sensor.

1. The air intake filter is clogged and needs to be removed and cleaned.

2. The coiling coils need to be cleaned.

3. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder
level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If the above fails to help solve the problem, replacing the Humidity Sensor is certainly an option. But, before you jump into it, make sure you have an accurate wiring diagram, so you know which sensor is which. As the part does not come with installation instructions.

I hope this helps you and thanks for choosing FixYa.

Unit doesnt seem to be removing humidity. its


Check the auto defrost sensor. They are known to become defective. Bypass or remove the device and unit will run normally, almost. WARNING: without the defrost sensor the unit will tend to ice up in cooler ambient environments. If sensor is removed watch carefully and only use in summer months. The dehumidifier may also be fixed by replacing the sensor but the design for repair is different and requires a costly modification.

I have an lg dehumidifier LHD 45EL. The humidity reading reads 15% higher than a stand alone humidistat and the unit will go on for a short time even though the set humidity level is 70%. What gives?


Possibly the primary humidity sensor behind right side grill. Unit MUST be unplugged from outlet. Take right side grill out, unplug sensor from wire socket and plug back. If no help, you need new sensor.

20% humidity reading


Hi, I just cleaned my dehumidifier and had the same problem as you. I used a spray water bottle and was not aware that the humidity sensor was being soaked. Very stupid of me!! Luckily I have two same dehumidifiers and used the other sensor to replace the one that I so stupidly ruined, and behold my machine worked again. Now I have to buy another sensor. To make sure we are talking about the same thing, my sensor is white,about 1 inch by 1/2 of an inch. It as 4 wires connected to it. To access it you remove the water tank, you will see 2 screws. Remove those, and pry the front panel loose. Be careful the top of the panel is held by two plastic hooks, they break easy. The sensor is located on the right side just above the radiator, under a produting oval lip which as foam around its rim. The wire colors are red black blue and yellow. Good luck Herman
