Question about Kenmore 54501 Dehumidifier

1 Answer

Fan runs, but unit doesn't remove any water. Dryness setting is stuck and won't change. How can I tell whether the problem is electronic (control board) or mechanical (compressor)?

    Compressor is not running. I've disassembled the unit somewhat (front, rear and side panels off), so I can see the boards, etc. There are no burnt wires or other indications of damage.

    Can you provide troubleshooting instructions that I can follow to determine if the control board is faulty? Also how to perform continuity checks on the compressor and overload?

    Thanks.

Hi,

First check if the compressor is running, if you hear a buzzfor a few seconds, every few minutes, then you have a faulty compressor or atleast faulty start components on the compressor. Disconnect the power cord from the power source. Remove thecompressor cover and check for any burnt wire connections on the compressor oroverload. If you do not see any burnt wires then the failure could be the controlboard, an open overload or open compressor windings. Some continuity checkswould be needed to see if the compressor and overload is okay. Youmay also have a control board failure.If it not working properly, then you have to change it.

My dehumidifier full light is on but the unit is empty and the fan motor won't work. Is there a way to reset it? Is that why the fan motor won't work?


This is generally causes by improperly installing the water collection bucket after removing it to empty it. Or the float valve in the top ow the water bucket s stuck in the "UP" position. Some Maytag models have a float control that moves from left to right, depending on how much water you want it to collect, before having to empty it. It may be stuck in the center position and needs to be moved left or right.

When installing the bucket, be sure that it fits into the holder "squarely" from top to bottom and makes contact with the bucket removal safety switch at the back of the bucket holder. When installed properly, the bucket should not tilt down at the bottom.

Hope this helps you and thanks for choosing FixYa.

Runs but doesn't work (no water accumulates)


It sounds like what you hear working is the fan. The unit also has a compressor; if the compressor is bad or the freon is gone, the fan will run but the coils wont cool to remove moisture from the air.

DDR2504 dehumidifier has always worked well. Now the fan runs and all seems normal, but the humidity is not dropping and you can tell that the dehumidifier is not cutting in and out. I do not have it on...


derkfarm - It may simply be a case of the humidity extraction level being set to high and/or the air intake filter needs to be removed and cleaned.

Solution: Lower the humidity extraction level to 32 - 35% and clean the air filter.

If the unit is in a basement, the ambient air temperature at floor level is colder than at chest level. Dehumidifiers don't work well at temperatures between 40 - 60 degrees F.

Solution: Set the unit up off the floor on a sturdy table, cabinet, counter top, etc. It must be sturdy enough to handle the weight of the unit, plus a full tank of water and the vibration, while in operation.

Any or all the simple solutions above may solve the problem. But, we won't know, until you try them.

Please let me know if it helped or didn't solve the problem. Thanks.

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.

My dehumidfier won't shut off. I check everything out and it's good but it just won't shut off it keep running.


It may be, that you have it running in continuous mode, rather than timed mode. Also, most dehumidifiers fans will run almost continually, to keep the air moving, so the humidity sensor can pickup and increase in humidity, if there is one.

If the above doesn't seem to be the problem with your unit, turn The Master ON/OFF Switch to OFF and unplug the unit for 12-15 minutes. This will give the electronics time to reset themselves, if necessary.

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

You may have the humidity level set to high. If it's above 60%, that's what it's going to maintain, not remove. Set the humidity level on the lowest setting and try again. Whether you're using the hose or not, I don't suspect it's playing a role in it. Also, clean and reinstall the air intake filter.

Hope this helped you solve the problem. Please let me know. Thanks.

How do you know if it is on?


Assuming that the unit is plugged in to an outlet that has power, press the ON button and a green light should come ON. That will indicate the unit is getting power and is ready to function. If however, you have the humidity level set to high and it's equal to or higher than the humidity level in your home, the unit's compressor and fan will not turn ON and run. Keep in mind, the humidity level, whether it's and LCD readout screen or just a minimum and high setting, that's not the amount of humidity that the unit will remove. It's what it will maintain. So, setting it as low as possible, should cause the unit to start functioning.

If it doesn't start, check the water collection bucket, to be sure that it's installed properly and is making contact with the safety trigger switch. If it's not making contact, the unit will not turn ON.

Hope this info helped you. Please let me know. Thanks.

My dehumidifier compressor runs and then shuts off, then runs and shuts off, continuously. The fan continues to run. It seems to be pulling water, though it's hard to tell how much because I have a...


Part of the problem may be that you have the humidity level set to high. The fan runs constantly to move the air around. When the unit senses a humidity level higher than what you have it set for, the compressor turns ON. Once it's ON, if the humidity level is short lived, it turns OFF.

Try setting the humidity level to the lowest possible setting. Usually, that 45%. If the humidity level in you home is higher than that, the compressor should turn ON and run until either the bucket is full or the humidity level reaches 45%. If this doesn't solve the problem, turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet for 12-15 minutes. Plug the unit bakc in, turn the Master ON/OFF Switch to ON and set the humidity level at it's lowest setting. Allow the unit to run until it cuts OFF and check the bucket for water. Hopefully that 12-15 minute time out allowed the unit to reset itself.

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

You may have the humidity setting to high. Try lowering it to 45%. Or if yours doesn't have an LED Screen, set it for minimum. Also, check and clean the air intake filter, if you haven't already. Keep in mind, most dehumidifiers have a fan that may seem to run constantly, but the compressor doesn't turn ON. The fan is circulating air, in a effort to detect humidity levels that are higher than what you have the humidity removal set on.

Hope this helped you.

Dehumidifier does not see to be collecting water, fan is running but no water from hose


It very well maybe, that you have the humidity removal set to high and it's not sensing any humidity to remove. For example, if you have it set on 65 - 70%, that's not how much humidity it's going to remove. It's the level of humidity it's going to maintain in your home. To remove moisture/humidity, the setting should be low, like 45%. As far as the fan running ... many units are designed that way, in an effort to help keep the air circulating and also to defrost the cools.

If you want to test the unit, to see if it's working properly. Place the dehumidifier in the bathroom and set it at 50%. Turn the shower ON and let it run for 20 minutes with the bathroom door closed and without the exhaust fan running. And check on it after 20 minutes. More than likely, there' will be water in the bucket.

Also, there's routine maintenance that should be performed regularly. Clean the air intake filter, clean and wipe off the the compressor coolant coils, and check for clogs in the drain line of the unit.

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