Question about Haier HD656E Dehumidifier

Open Question

Hi - the temperature and humidity readings on my dehumidifier are inaccurate - both are reading to low so the unit won't start up - its reading 32F when the room is 56F - can I simply bypass these sensors and hard wire it to run when the powers on - I have the top off and the sensor/on/off wires exposed but I'm bot sure what all the wires are for. Thanks. Scott

SOURCE: unit wont run but lights up. It reads low humidity

Hello,

First, make sure the reservoir is empty. If you plug the unit in and see a green power light, but the unit won't run, make sure the reservoir is properly inserted. Many dehumidifiers have switches or sensors to make sure that the reservoir is placed so that it won't leak. Look for these sensors and make sure the reservoir is engaging them. If your dehumidifier has a float or switch to indicate a full reservoir, make sure this switch isn't being tripped accidentally.

Good luck.

SOURCE: Model HD656E dehumidifier ran well

Hello
There should be a button on top for the fan speed,High and low.If your running it in automatic with say a humidity setting of 58 to 60,the fan will run low unless the unit sences say 70 to 80% humidity.

There is a filter in the back you may want to clean it, before you know it it will be hot and humid again.

To answer your question the unit is working fine.You can set the humidity level to its lowest point then try high speed,just for a test.

Hi,
It could be just the sensor, but not likely... many times it is the circuit board that goes bad, making the repair almost prohibitive.. as the circuit board, if you can find one, is often half or more the cost of a new unit...
But you are correct... if the unit thinks the humidity is 20% then it will not bring on the compressor...that is what is happening...

We just bought a new Friedrichs dehumidifier for our damp basement. The temp is reading 81 and the humidity 63 and it's been running for 2 hours. The basement is about 1000 sq feet and the outdoor temp...


Iris, all dehumidifiers generate some heat while in operation. However, it may be generating higher temps because of it's location. Dehumidifiers don't work well in temperatures below 65 degrees, In fact they struggle below that temp. Unless it's a Low Temperature unit, designed specifically for basement applications.

For example, the ambient air temperature never changes more than 10 degrees F throughout the year.
The air temperature at floor level (where the dehumidifier is placed) is colder then the air temperature at shoulder level. Raising the unit up off the floor onto a sturdy table, counter top, etc, that can handle the weight of the unit, plus a bull bucket of water, will generally solve the problem.

Be sure to clean the air intake filter regularly. At least once every 2 weeks. And wipe off the cabinet and the front louvers, when you change the filter. Always, turn the unit OFF & Unplug it, before removing the filter. Never operate the unit without the filter in place. Doing so could cause damage to the unit.

I hope this information has helped you and thanks for choosing FixYa.

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.

No, it may mean that you don't have the humidity extraction level set low enough. The lower the setting, the more humidity it will extract. Try setting the extraction level at 35%, to see if the compressor turns ON.

If yours is being used in a basement, the 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.

Unit seems to not read correct humidity. only operates for short time(one minute or less) then turns off. i know the air is humid, + 90%


John, there are 5 basic, yet solvable reason for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. 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 none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

John, I hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

If the humidity level is at or lower than 30%, the unit won't turn ON, until the reaches 35 - 40%. It's rare for the sensors to go bad. Just keep in mind, the dehumidifier is reading the humidity near the floor, not up at say, chest level. Humidity levels change every season, so this really would not be that unusual. Make sure that your clean the air intake filter regularly. Cleaning and wiping down the coolant coils would be a good idea, too..

Hope this helped you. Please let me know.

Humidity sensor reads to low and does not kick the machine on. The readout seems to always be at 20% and wont kick on till 35% Is there an adjustment i can make to tuen the unit on?


It probably doesn't need adjusting, It's simply a case that 20%, there's not enough humidity for the sensor to read. But, at 35% there is. I'd say, your dehumidifier is working as it should.
FYI - there is no adjustments to change the factory settings.

Hope this helped you, chu.

New unit, try using in basement. nothing happen, should humidity settings be high or low? Dose humidity level be high? In the bucket whats the plastic cup about? do something alow water to enter bucket?


If you trying to remove humidity, the setting or percentage of humidity to you want to remove should be set low. it's actually the humidity that will be left in the air. In the Hot Summer months, you want lower humidity, as opposed to the Winter months, when you want higher humidity.

"Plastic cup inside the bucket" - that's got me stumped. But, I suspect, it may be a float valve to turn the unit off, once the bucket reaches the full level. The water enters the bucket through a drain tube or hole from inside the dehumidifier, above the bucket.

By best advice, since this is a new unit, that you recently purchased, is read the Owners Manual/User Guide and become thoroughly familiar with the proper operation of your Dehumidifier, as well as how to properly maintain it. As, they aren't maintenance free.

The unit is set at 40%...stiill reading hi...over 3 days


reading of hi, is only ambient reading.
you probably have more humidity problem than your dehumidifier can handle. try adding one, or getting larger capacity model

Humidity reading is 16% when actual humidity is 46%


Running a dehumidifier when the ambient temperature is to low will cause freeze-ups. Also running it when the dew point of the moisture in the air is to low will cause it to freeze up when you set it to low which would be a higher number on the set point.

The hand written number on the probe casing is probably a quality control inspector number.

Temp and humidity levels are not correct


It sounds as if the temperature sensor probe is touching the cold coil inside. The sensor is located in the incoming airflow, in front of the cold coil. It must not touch the coil. This should be visible with the cover off. You can gently bent the sensor away fron the coil, 1/4-1/2" of clearance is plenty.
