Model DH 305 serial#502TAWM03857 unit powers up when reservoir is inserted and humidity dial turned up to max but fan doesn't turn. Is the fan motor bad or could another part be causing this problem? Have had the unit in my home's crawlspace removing dampness caused by flooding and functioned ok for about 7 to 10 days before this problem occurred

Lyle, your particular model is designed for the fan to function constantly. However, the fan running doesn't mean the compressor is always running. The reason the unit was designed this way, is for the air to be continually moving, and when the humidity sensor picks up a rise in the humidity level (above where you have it set) the compressor will turn ON and extract that humidity.

Your unit is working as it should. Thanks for choosing FixYa.

hi,


It has high and low fan speeds, variable humidity controls including 'Max', and automatic shut-off with indicator when the reservoir is full.


so pls recheck the automatic shut-off when the reservoir is full .

may be the automatic shut-off botten are stymed.



good luck

Kate, There are several basic things that can cuse the problem you seem to be having. At least you're doing the steamy bathroom test. You must have read one of my relies to someone else.Keep in mind, the lower the humidity extraction percentage or number, the more humidity it will take out of the air.

1. The air intake filter is dirty or clogged.

2. The humidity extraction level is set to HIGH. Lower it to 32%.

3. Obstructed air flow around the unit. You must maintain a minimum of 12" clear air space around the entire unit, while in operation.

4. The ambient air temperature at floor level is between 40 & 60 degrees F. This is true in basement applications and the unit will not function properly. Unless it's a Low Temperature unit. Placing it up off the floor on a sturdy table or counter top that can adequately hold the weight of the unit, plus a full bucket of water, usually solves that problem.

Worse case scenario, the compressor needs to be recharged with refrigerant gas (R14). But, that doesn't happen that often.

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

Depending on which mode you have the unit set on, will determine if it shots OFF entirely or the fan continues to run. In the Constant or Continual mode, the compressor will turn OFF, once the humidity extraction level has been reached. But, the fan will continue to operate, in an effort to keep the air circulating, so that if the humidity level rises, the compressor will turn ON and start extracting again.

In Timed Mode (usually 2 hour or 4 hour) , when the compressor turns OFF the fan does too.

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

Bryan, it may imply be a case of the humidity extraction level being set to high. Lower the level to 35% and see what happens. As far as the fan running is concerned. Most dehumidifiers are designed for the fan to run, even if the compressor doesn't turn ON. It's designed to keep the air circulating and if the humidity rises above the setting you have it on, the humidity sensor will pick up this change and turn the compressor ON.

Also, remove the air intake filter to see if it's clogged and needs cleaning. Maintain at least a minimum of 12" of free air space all around the dehumidifier. Poor air circulation will prevent the unit from working properly. As will, to low an ambient air tempeature. Most unit struggle to work at temperature between 40 & 60 degrees F.

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

So far, you've completed all the right tings, that I would have suggested. Now, take a look at the humidity setting on the dehumidifier. If it's set high (above 65%) there's not much chance that the unit will collect any humidity. It simply is just maintaining what it's set on. Lowering the setting to 35% will have a much better affect in removing the humidity/moisture.

There is an in home test you can do, to make sure the unit is working properly. Place the dehumidifier in the center of a bathroom and turn the shower ON hot enough to generate steam. Turn the humidifier ON and Set the level at 35%. Do Not turn the bathroom's exhaust fan ON or leave a window open in the bathroom. As you exit the bathroom, close the door and wait 15 to 20 minutes before returning. After entering the bathroom, turn the shower OFF and allow the unit to run for 5 more minutes. Then check the bucket for signs of water. If you find any, the unit is working as it should. Also. the dehumidifier, when in operation should have a minimum of 2 feet of clear air space around it. The fans on many units run almost constantly, to recirculate the air and if any increase in humidity is sensed, the compressor will turn ON. This is particularly true, if you operate it in continuous mode, rather than a timed mode. Also, be sure that all exterior doors and windows are closed when the unit is in operation.

If after doing the in home test, the bucket did not show any signs of water, either the humidity sensor has failed and needs to be replaced or the compressor needs to be recharged with refrigerant.

Find out what the cost to repair the unit will be, before committing to it. As your model has been discontinued and it may be less expensive to but a new unit. Hope this helped you. Please let me know.

I'm assuming the that you determined the unit is getting power, because the lights on the dehumidifier light up, when you turn Master ON/OFF Switch ON.

If that's the case, it may simply be that the humidity level you have it set for is equal to or higher than the humidity level in the house. In which case, lower the humidity level to it's lowest setting to see if the unit turns on then. Also, check the water collection bucket, making sure it's installed properly and is making good contact with the safety trigger.

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.

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.

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.
