My Kenmore dehumidfier 50 freezes up.

I cleaned the filter and used a air gun to clean the condenser. It freezes up on low settings. The Model #25357510791

IS THE ROOM HUMIDITY LOW. IF IT IS BELOW 30% THE HUMIDISTAT WILL SHUT DOWN THE UNIT. THE AMMBIENT TEMP SHOULD BE ABOVE 65 DEGREES AND THE HUMIDITY SHOULD BE ABOVE 50 %.

SOURCE: kenmore dehumidifier runs but won't collect water

Hi,
If you haven't done so already, try removing and cleaning the inlet filter screen which is almost certainly just behing the inlet grille. It may slide upwards out of the casing or downwards unto the bucket area. If this is blocked with fluff then no moist air will get to the cold pipes, so little or no water will be extracted. There's also a chance that the humidity sensor is clogged with fluff, so fooling the system into thinking the room is pretty dry, in which case the compressor will probably not run.
A running compressor can usually be detected as a deep throbbing from the machine. If it is running, but not cooling the pipes behind the intake grille, then you may have lost the refrigerant from the system via a leak. If the air coming out of the machine is warm (caused by the compressor running) but there is no water produced this may be the cause.

Explore along these lines and let me know what you find.
Cheers, D

SOURCE: Unit is repeatedly freezing up

Almost all dehumidifiers now have automatic defrost, but if you are seeing frost is just one small area, it means there is a refrigerant leak. Check your warranty to see if the sealed system is covered longer than one year. Generally, if it is, most manufacturers will replace the unit (rather than repair it, as the repair is rather expensive compared to the cost of a new unit). If you do not have any sealed system warranty coverage left on it, don't fix it. Buy a new dehumidifier.

SOURCE: Kenmore 54501 turns on but nothing happens in my damp basement

A dehumidifier heats and cools the air to remove moisture. Most are like a small air cond. The Condenser coil is right in front of the evap.coil. So the compressor may not be coming on. Does it sound the same as before? It may be low on freon. You will have to get in there and listen and feel the lines at or near the compressor, Learn how to get down in there to the compressor. Run it for 10 Mins. unplug it, open it up, and feel the lines. Some lines should be or can be HOT to the touch. Some should be cool. The smaller the line the hotter it should be, and the compressor should be warm (to hot) to the touch. repost for more info.

Frozen filter


This can typically be caused by two items, low refrigeration gas or insufficient air flow. I would shut the unit down, unplug it and let it set for a day to thaw out. Clean all the air passages and replace the filter. Plug it in and turn it back on. If it continues to freeze you probably have either low refrigeration gas or a fan that is not opperating properly.

Hello , I have goldstar dehumidifier model #DH40 . It's freezing from back grill? Can you please give me some solution to it? Thanks for you're help


It sounds like not enough air flow. clean the filter. I would suggest unplugging it and let it set for a day to dry out then replace filter and clean the air path including coils.

The top of the unit has alot of condensation on it. so i am wondering if its freezing up inside. Have set point at 55% what can i do to fix the issue


A little condensation is not something to worry about. But, a lot can be caused by a dirty or clogged air intake filter. Which can also cause the cooling coils to freeze.

Turn the unit OFF & unplug it, before removing the filter for cleaning.

Also, maintain 12" to 18' of clear air space all around the unit.

If the unit is in an extremely moist or damp environment, 55% is not really a low setting. 35% would be more appropriate for this type of environment.

Hope this helps you to troubleshoot and solve the problem. Thanks for choosing FixYa.

I bought the FriedrichD50. It worked fine in 2 weeks with the built in pump. After I disconnected the drainage by using the bucket, no water comes out. Does it make sense the machine runs 2 days straight...


Yes, it does make sense, depending on what humidity extraction level you have it set on. Set to high, it will will remove little to low condensation/humidity. Set it to 35% or if you have an analog model (no LED screen) set the humidity extraction knob on Maximum Also, be sure that the air intake filter is clean.

Kenmore dehumidifier will run but collects no water and turns off and fan is not turning on


There are 5 basic, but solvable reasons 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%. If you have an analog unit
(No LED screen), set the humidity extraction knob on Maximum.

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.

After an hour, the refrigeration unit begins to freeze up. Condensation appears on top of the dehumidifier cabinet. I have eliminated all obstructions to air flow, including the filter. What can I do?


Hi,

The most common cause of frost and ice buildup on a dehumidifier is because the unit is operating in temperatures that are too cold. Many dehumidifiers are not equipped to run at temperatures below 65 degrees Fahrenheit.
To fix this problem, Position the dehumidifier in an area where there is at least one foot of clearance around the unit in order to allow for proper air circulation during its operation. Close all windows, doors and other outside openings to make sure your unit isn't attempting to remove moisture from areas outside of the immediate room. Determine the temperature of the room by checking a nearby thermostat or by using a hand-held thermometer.

Check the filter for dirt and buildup. Unplug the unit from the electrical source and check the filter by opening the filter compartment. If the filter is dirty, it will restrict airflow through the unit and lead to freezing. Soleus recommends lightly vacuuming the surface of the filter to remove dirt. The filter also can be washed in warm water if it is extremely dirty. Once clean, place the filter back in its compartment. Allow for the ice to melt and then restart your dehumidifier.

I have a Zenith dehumidifier P/N 3850A20500H. It was working, and now its not. I cleaned the air filter, and the fan spins just fine when I spin it by hand. Any suggestions? Thanks, Gary

The dehumidifier freezes up and continues to run so it never melts.


Check the air filter. Freeze ups are often caused by low airflow across the cold coil. A dirty air filter can severely restrict air flow. Replace or wash (if a washable type) the filter and allow the dehumidifier coils to defrost completely. Reinstall the filter and be sure to locate the appliance so that air flow in and out of it is not restricted in any way (not up against a wall, behind a door, curtains, etc.) and restart.

If the unit has been run without an air filter, the cooling coil fins are probably choked with dust and dirt. They should be cleaned with a product designed expressly for this purpose such as:

Evaporator coil cleaner is available from many hardware and "big box home supply stores" such as Lowe's or Home Depot.

Use only as directed, and buy filters! it's much easier to replace filters than cleaning coils.

I hope this helps and good luck! Please rate my reply "4 thumbs up" if it was helpful. Thanks!
