Question about Maytag M3DH30B2A Dehumidifier

2 Answers

Compressor turn on briefly, no water collected

After I plug in the device, I turn it on and select a setting. Immediately the fan starts blowing. After a few seconds, the compressor (I assume its the compressor) turns on for approx. 6 seconds, then turns off. The fan runs for another 30 seconds, the compressor comes back on for another 6 seconds. This process repeats, and no water is collected. I purchased the dehumidifier from a friend, and it's about 3 years old. Any ideas? e

    ...just to add to the above note, I haven't taken the product apart, because I don't know if it's under warranty (it was a gift, in 2004)

Sounds like the low pressure cutout switch is stopping your compressor running, especially if the "6 seconds" you mention are exactly the same length. Not enough refrigerant would be the usual cause, but the reason for the refrigerant loss is harder to tie down - possibly a seal or a loose valve seat or even a pinhole in a copper tube. Best solution now would be to take it to a refrigerator mechanic to top it up and check for leaks - get a quote first to check - 'fridge gas is getting costly. Other possible solution is that the low pressure switch itself is faulty, relatively inexpensive to replace (but unfortunately you will need at least a partial gas recharge on most types of system after) - your fridge gas guy will be able to check very easily if there is adequate gas in the system, and should check this low pressure switch if there is not.

Dehumidifier keeps running and no water collects in the bucket

Sounds like a refrigeration problem, I am assuming the fan operates. Unplug it and let it set for about an hour. Plug it in and see if the compressor starts. If it does and you do not get water It is either low on gas or the compressor has failed. If the compressor does not start but hums it would need a new capacitor. If nothing the thermal overload has probably failed. This should get you started. Good Luck. If it is to involved they are not that expensive to replace.

Kenmore dehumidifier compressor on but doesn't collect water

clean the condenser in the front or the filter if it has one. no air flow to cool it down will result in overheating and no condensation collection across the evaporator coil.

Does not extract moisture from the air. It runs and cycles on and off. I have changed the filter, turned the device off and reset it. Changed the humidity setting. The device is about 4 years old.

Fred, here is an in home test, that will determine whether your unit is working properly or not.

Please the unit in the bathroom, plug it in, turn it ON and set the humidity level at the LOWEST setting. Turn the shower On hot enough to generate steam. Do Not turn the bathroom's exhaust fan ON and make sure any window(s) is closed. As you exit the bathroom, close the door. Wait 15 to 20 minutes before reentering the bathroom. Then turn the shower OFF and allow the unit to run for 5 more minutes. Then, check the water collection bucket for any signs of water. If you find water in it, it's working as it should. It may simply have been a case that the humidity extraction level was originally set to high.

If you found no signs of water in the bucket, the humidity sensor in the unit may have failed or the compressor is low on refrigerant. Either one is repairable, but the cost of troubleshooting it, finding the part and the time repair it, may exceed the cost of a new unit. As, yours is a 4 years old unit.

Hope this helpd you to troubleshoot and solve the problem. Please let me know. Thanks.

Kenmore Elite 70 pint unit. Compressor appears to be frozen. Fan runs and compressor attempts to engage but immediately shuts down. Any suggestions. Unit is only about 2 years old.

Hi, I think you got it figured out...
There can be many reasons why a dehumidifier willnot work or collect water.

Fan runs ,coils are room temp. should they be hot or cold , no water is collecting in bottom

A dehumidifier is basically an air conditioner, so some coils should feel hot, the others should feel cold.

If no water is collecting, then the unit's compressor is not starting. Typically you have four possible failures causing this: the switch/wiring for the compressor has an open circuit, the motor-start capacitor for the compressor has failed, the compressor itself has failed, or all the refrigerant has leaked out.

If there is evidence that it is 'trying to start', but then clicking repeatedly, this can be a symptom that the refrigerant has leaked out, as some devices have a pressure switch to prevent compressor damage.

Also, a failed start-capacitor can also cause the click-click noise if the device has a current limiter switch on the compressor.

So the short answer is, it's broken :)

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.

Oil inside the water collection res

the compressor runs in oil. suspect you have a quite bad leak and loss all the gas - hence no water collection and the compressor oil is being pumped out thro the leak
