Question about Maytag M7DH45B2A Dehumidifier

1 Answer

Fan runs but does not collect water

The fan kicks on but the coil never gets cold and therefore water does not flow into the bucket. I took the back cover off and noticed that the small black tank on the bottom of the unit (I'm assuming it's the condensor) is quite hot. Any ideas?

It sounds as though the compressor is not running or the machine is low or out of refrigerant.

Does not collect water in bucket but runs all the time


Does it have a filter?

"
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.

Unit runs but no water collects in bucket. Unit is over a year old and has run continuously that whole time. Up till now it has performed beautifully. Is it just worn out?


Hi;
Your dehumidifier is similar to a refridgerator or air conditioner. It has a compressor and coils, and a fan. Basically, the unit has to **** in air with it's fan, and as the humid air goes across the cold coils, the humidity condenses in to water. If the coils are not getting cold, they won't condense any water, or if the fan isn't running, or the coils are dirty. If you check your unit over, see if you can tell if anything isn't working. Make sure the control knob is set at the highest setting. If the compressor lost it;s refridgerant charge, and won't get cold, it isn't probably worth fixing

No moisture


check to see if the coils in the back are cold. if they are not, you either have no freon or the vent in the front is blocked and the condenser coils have no air flow to cool down. if they are, there might not be sufficient air flow across the evaporator coils or the air is already dry.

also, if the bucket switch isn't activated (due to the bucket not being in all the way), the fans will come on, but not the compressor.

Goldstar DH304 Freezing up / no water in bucket


Thermostat or the temperature control module are not working properly. Also make sure that your fan blades are not broken or warped as this will cause you a problem. Also if the coils have or do get iced up then it will be a low coolant problem. But this is a thermostat or temp control problem

Running but not collecting water...


Dehumidifiers have only a few components, and operate on the same principle as a refrigerator, freezer, or air-conditioner.
Components Residential dehumidifiers have a cooling system made up of these primary components:

  • The compressor is the quiet motor (engine) of the cooling system. It's the black, football-size component at the bottom of your dehumidifier. The compressor runs as long as the dehumidifier humidistat (the humidity-sensor) calls for a reduction in the humidity.

  • The condenser is a series of finned tubes, similar to a radiator. It's usually near the circulating fan.

  • The evaporator is located near the back of the dehumidifier, right above the water-collection container. It also resembles a radiator or a coiled-up set of tubes. When the dehumidifier's humidistat senses increased humidity, it cycles on, which starts the compressor and circulating fan.

  • The circulating fan circulates the air over the evaporator and condenser coils.

Principle When the unit runs, the circulating fan and compressor also run. The fan continually draws room air over the evaporator coils, which are cold, and then over the condenser coils, which are warm. Because the evaporator coils are cold, the moisture in the room collects on them--just as the outside of a glass of icy liquid "sweats" on a warm, humid day. When the moisture on the coils increases, it drips off of the coils into the collection container.

The air then flows over the warm condenser coils and out into the room. This process removes water from the air and, because of the heat from the fan motor and compressor motor, the exiting air is somewhat warmer, as well as dryer.
