    Thank you.



    I am not able to find a part number or even a repair parts supplier.



    Can you help in that area.

  • flogman Sep 27, 2010

    I was just talking to Encompass Parts and they sent me a sketch of BHD-501, however the part I am looking for is not on the sketch.



    Apparently,my unit is an orphan.



    Thank you.

    Thank you for your four thups up voding.

    Moreover if you can not find a new control board you can remove yours and is your able do it your self or ask you nearest elecronic techincian to replace all realys that are on the control board. You will be suprised by the results. By 90% the fauld on electronic boards especialy old models are due to an overworking relay.

Frigidaire FDL50s1 runs continuously but will not collect water. What could be the problem & can it be fixed?


Thank you for your post, K!

I understand that your Frigidaire dehumidifier is continuously running and it is not collecting water. This can be caused by a dirty filter. A dirty filter can restrict air flow which will allow your dehumidifier to not pull in air. I would recommend checking your filter to make sure it is clean.

Frost on the coils within your dehumidifier will also cause your dehumidifier to stop working as well. You should check to make sure that there is not frost visible on your dehumidifier. If you do locate frost you would need to perform a manual defrost on your dehumidifier and you can do that by disconnecting power from it for at least two to three hours.

If these steps do not resolve your issue you may need to reach out to the manufacturer for a proper resolution. I hope this information is helpful to you. -Matt

Coils freeze up. completely blocked. have to shut off to thaw coils. located in basement.


After the unit is totally thawed and dried, turn the unit Off if you haven't already and unplug it. Remove the filter and clean it. If it's really dirty wash it with warm water and dish washing liquid, thoroughly rinse it and allow it to completely dry, before reinstalling. DO NOT operate the unit without the filter in place.

Because the air temperature in a basement is colder at floor level, than at shoulder level, this caused the coils to freeze. Dehumidifiers do not work well at temperatures at or below 60 degrees F. That is, unless, it's a Low Temperature model, designed especially for basement applications. Obviously, yours isn't a Low Temp model.

To overcome this, place the unit up on a sturdy table, counter top, etc, that can handle the weight of the unit, as well as a full bucket of water. The higher off the floor the better. This way, the ambient operational temperature will be higher and the coils will have less of chance to freeze again.

I would suggest that continue to monitor the unit and if you notice that it's doing more than a little frosting on the coils, turn the unit OFF immediately. A little frosting is normal and the deforst mode should kick in and thaw the coils. When this happens, the compressor should automatically shut OFF, but the fan will continue to run. Once it's defrosted, the compressor will start again, if necessary.

I hope this helped you to troubleshoot and solve the problem. Please let me know.

Why is my dehumidifier icing up.


The room temperature is probably too cold, or there's poor airflow
Here's some info that should help you figure out what's causing the problem:

If the evaporator coil is frosting completely and evenly, the most common cause is that the room temperature is too cold. Most dehumidifiers are not meant to be used when the room temperature drops much below 70°F and certainly not below 65°F (depending on humidity). There are however some models called "basement" dehumidifiers which are.

Another possible cause on standard models is poor air flow through the unit. If the fan motor is not turning fast enough (or at all) or the evaporator, condenser or filter (if used) being plugged can also cause this symptom .

Humidifier gets ice on top of cabinate. It still produces water.


Most dehumidifiers have a defrost cycle that they run through, as needed. But, apparently, your is not functioning. Eventually, yours will stop collecting moisture, if this continues. In the interim, I would suggest turning the Master OnN/OFF Switch to OFF and unplug the unit until it thaws. While it's unplugged, remove and clean the air intake filter on the front of the unit. If it's clogged it causes the unit to strain and may cause it to ice up. Once the filter is clean and the unit is un-thawed. Plug the unit back in and turn the Master ON/OFF Switch to ON and set the controls as you normally do. Hopefully, that period of being unplugged will have allowed the unit to reset itself and work properly.

I have included a link to your Owners Manual that you can download and print for future reference.

Need a repair shop in the baltimore area to look at my dehumidifier runs but wont pull water


It's cold outside. If the temperature is too low, the cold coils will just frost up and you won't get much water 'pulled'.
Check to see if the cold coils actually are getting cold when the unit is running and the control is set to cause the compressor to work-not just the fan.
If the coils are cold and full of frost or ice, the room is too cold for the dehumidifier to work. You'll have to raise the temperature of the room or wait for warmer weather.
If the coils never get cold, the compressor might be bad or the unit might have lost its freon.
I wonder, though, if it's just too cool and dry right now for a dehumidifier to be pulling more moisture out of the air.
Hope this helps!

I have a dehumidifier (Emerson I believe - sorry don't have the model # right now) in a very cool basement (55-60 degeres). When I turn it on the coil quickly frosts up as expected and a while later the...


Dehumdifiers work by cooling a coil below the dew point temperature of the ambient air. When this happens frost or water will form on the coil. Most room dehumidifiers work with the room temperature above 65 deg F. It works well when the temperature of the room is 65 deg F or higher. But when the temp is below 65, it won't work because the coil does not reach the dew point.

There are cold temperature dehumidifiers that are designed to work in colder environments such as basements. They can work in a environment as cold as 40 deg F. Check your owners manual to see what type of humidifier you have to see what is the minimum operating temperature for you unit. Hope this helps you.

Dehumidifier


Most dehumidifiers these days have a built in defrost control, which turns the compressor off when the coils frost up while the fan continues to blow to help melt the frost off, so if it is frosting you may need a new defrost control, but first check the following: If your model has an air filter, clean it, as restriction of air flow will contribute to icing. Try to move the unit to a warmer location. Usually the best way to do this is to get it above the floor as far as possible, as the air temp is warmer closer to the ceiling than it is at the floor. Make sure there is plenty of room for air to circulate. (don't push it against a wall)

Not working


Hate to tell you, but it may be a goner. Many units have a rectangular air filter that may be clogged, but I would still expect to see some moisture removal. Without exact model I'll have to be general,.... remove cover (front or back, depends on model) to see cooling coils. If the compressor is running, these coils should be wet or may have a light frost on them for a time. Not = refrigerant leak. (not economical to repair) If you see one small area of ice,... it's also a goner. If the compressor does not run you could have a bad compressor, a bad defrost control, or a bad control / humidistat. Other than the filter or possibly a fan motor, these unit are rarely economical to repair.
