Question about Maytag M3DH30B2A Dehumidifier

Mold collecting on coils

When I took out the air filter and looked inside, it looked quite dirty on the face of the ribs that cover the coils. So I took the unit apart and discovered tufts of mold. Why is this happening? Should I attempt to clean it myself, and if so, how?

Quit collecting water


Hawkster, there are 5 basic, yet 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) turn the humidity extraction knob to 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.

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

Dehumidifier is not collecting any water. Took panel off, and saw that fan is not working. What do i do now?


sciocci, the fan doesn't operate all the time. It operates when the dehumidifier is collecting humidity/water from the air or when it is operating in continual mode (draining water into a floor drain). So I'm not sure what you discovered is really a problem at this point. Particularly, since you the "dehumidifier is not collecting any water". Which to me, indicates that it was running, but without success.

With that in mind, I suggest you start with troubleshooting the basics after you put the panel back on the unit.

FROST COLLECTS ON TOP


Hi, rewolff. The problem you're experiencing, with your dehumidifier is usually caused by basic things. That can be fairly easy to solved:

1. Air intake filter is either dirty or clogged: Turn the unit OFF & Unplug it before removing the filter.
Be sure the filter is completely dry, before reinstalling it.

2. Refrigerant cooling coils are dirty aand need to be cleaned. This will require removing the face of
the unit, to access the coils. They should be cleaned with warm water and dish washing liquid.
Then rinsed and thoroughly dried. After they are dry apply a light coat of WD40 to the coils.

3. Air obstruction. The unit requires a minimum of 12" clear air space on all four sides of the unit.

4. If the unit is being operated in a basement, the air temperature at floor level is colder then the air
temperature at floor level. Unless, your unit is a "Low Temp" model, getting the unit up off the
floor, on to a sturdy table, cabinet top, etc, that is sturdy enough to handle the weight of the unit,
plus a full tank of water, will usually resolve the problem.

Your model has been discontinued by LG, but they still support it. So, if none of the above solves the problem, contact LG Customer Service for more detailed trouble shooting at 1-800-243-0000.

I do hope this helped you to do your own troubleshooting and hopefully solve the problem. Please let me know. Thanks.

We need to have the condenser repaired or replaced. No water collects when machine is turned on. Where can I find a qualified repair man in Cumming,GA?


Before you have it repaired, there are several things you can troubleshoot and solve yourself, that won't require any repairs.

1. The humidity extraction level may be set to High. Lower it to 32 - 35%.

2. The air intake filter is dirty or clogged. Turn unit OFF, unplug it before removing and cleaning the
filter. If you wash the filer, it must be thoroughly dry, before reinstalling it.

3. Obstructed air flow. To function properly, there must be a minimum of 12" clear air space around
the entire unit.
.
4. The cooling coils are dirty and need to be cleaned. Remove the front cover and filter to access
and clean the coils with warm water and dish washing liquid. Rinse , thoroughly dry and coat
coils with a light caating of WD40.

5. The air temperature at floor level is between 40 - 60 degrees F. Most dehumidifiers don't function
function well in that temperature range. Especially in a basement application. The ambient air
temperature at floor level is colder than at chest level. Set the the unit on a sturdy table, counter
top, etc, that can handle the weight of the unit & a full tank of water.

Conduct an in-home test, to check humidity extraction: Place the unit in your bathroom, plug it in and set the humidity extraction level at 32 - 35%. Turn the shower ON hot enough to generate steam. Close any window(s) in the bathroom and Do Not turn the exhaust fan ON. Close the door as you exit the room and wait 15 - 20 minutes before returning. After the time has elapsed, open the bathroom door, turn the shower OFF and allow the unit to run 5 more minutes. Then check the water collection bucket for any signs of water. If you see any, the unit is working as it should and one of more of the above solutions took care of the problem.

If the unit showed no signs of humidity collection (water) in the bucket and you want to have it repaired. The closest Delongi Authorized Service Center(s) to you are in Florida (please see the following link) http://www.delonghiusa.com/index.php?service

I hope this helped you further troubleshoot and solve the problem without having to make a repair. Please let me know. Thanks.

Dehumdifier not collecting water.


It may be that the humidity level or temperature in the room where your dehumidifier is located is too low.

When the outdoor temperature is below 50 F, the indoor air will be dry even when the air inside is warm, therefore when it's cold outside the dehumidifier may collect little or no water.

Air conditioners will also remove moisture from the room, even if it's hot and humid outside, resulting in little or no moisture collecting in the dehumidifier bucket.

Some dehumidifiers have a deicer which turns off the compressor but keeps the fan running. When the compressor is off, moisture is not removed from the air. The deicer turns off the compressor when the room temperature is cold.

Some dehumidifiers do not have a deicer. If the room temperature is low enough, ice may form on the evaporator coil. The ice prevents the dehumidifier from removing and collecting water. If ice forms on coils, unplug dehumidifier until ice melts and room temperature rises.

The filter (on some models) may be dirty or clogged. If so, clean the filter. For instructions on cleaning the filter.

I hope this help to solve, if this answer solve it, remember to rate it. Good luck.

Frostguard 36 Dehumidifier runs, but collects no water.


unfortunately it sounds as though your refrigerant leaked out. If your compressor is running and no moisture, this is probably the case. What is the temperature of the air coming out?

ALL DEHUMIDIFIERS REQUIRE ROOM TEMPS TO BE AT LEAST 65 DEGREES AND A HUMIDITY OF AT LEAST 50 % TO OPERATE PROPERLY. ANYTHING LESS AND IT MAY FREEZE THE EVAPORATOR COILS. EVAPORATOR COILS WILL ALSO FREEZE IF THE COILS ARE DIRTY AND HAVE RESTRICTED AIR FLOW.TRY TAKING THE COVER OFF OF THE UNIT AND CLEANING BOTH SETS OF COILS INSIDE. THEY ARE COPPER OR ALUMINUM WITH FINS ON THEM.
ALSO CHECK THE FAN TO BE SURE IT IS RUNNING.
THAT WILL CAUSE AN OVERHEATING CONDITION AND WILL SHUT DOWN THE COMPRESSOR ALSO.
