Comfort-Aire BHD-301 Dehumidifier Questions & Answers
I thought the freezing up issue was resolved post cleaning of filter (didn't know there was one). Now, it will begin to run but shut off...the compressor doesn't seem to engage. How may I re
Glad to hear that cleaning the filter got us to the next step-- Congrats on the progress!
Now Tell me more about what you mean by: ..." THe compressor doesn't seem to engage."
If you can reach the compressor piping, you can tell if the compressor is 'engaging' - by noticing a drastic difference in temperature -- the outlet pipe-- usually near the top of the compressor can-- / -- and the inlet pipr -- usually further down the side or near the bottom of the compressor.
THe Discharge pipe can get VERY HOT at the top, and the Suction pipe at the lower level can get VERY COLD (likely close to freezing) at the inlet-- the lower pipe.
Be very careful!!, if the compressor has been running a few minutes-- as the outlet pipe can burn your fingers!
Anyway-- if you notice a great difference in temperature, while the compressor is running, you know that it is moving gasses thru the system-- and thus should be creating the condensing surfaces needed to cause water to be removed from the air flowing thru the coils.
Please check this, and let us know what you learn.-- then maybe we need to dig deeper--- Like where is a frost (or sweat) line appearing, -- and more about air flowing details.

Moisture collecting at the top front when running,
Well, sounds like you have a good cold section in the dehumidifier-- that is good!-- But I agree-- we don't want water condensing on the surface-- and we surely don't need it turning to ice!
A couple questions to help us get to the next level of trouble shooting this problem:
1.) How cold is the room you are running the dehumidifier in?
(Obviously-- the warmer a room is, the easier to remove moisture--
the colder the room, the easier to drop the air temperature well below the freezing point-- making ice.)
2.) Have the air filters been cleaned/changed recently?
A dehumidifier needs a steady fast moving supply of air across its whole condenser/evaporator surface, in order to remove the maximum amount of water from the air, and not freeze up. (I would winder if something isn't blocking the flow of air toward the top of the coil?-- so that the coil in that area is going well below freezing temperatures, and thus allowing water (or ICE!) to develop near the top of the coil?-- Can you check air flow for us?
3.) You have suggested a good solution,-- especially if the above problems can not be easily corrected: Turn off the unit every few hours, and allow the warmth of the room, to defrost the coil....
In fact-- just to make sure that the air flow is not being restricted by ice deep within the coil-- let it stay off over night-- or bring the dehumidifier into a much warmer room, to make sure no ice is still blocking air flow deep within the coil..
Let us know what you learn about air flow, and get back with us-- THen maybe we need to take the trouble shooting deeper insicde the device.
I hope this helps-- MB

There are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1, 2. & 5.
1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a mechanical unit,
set the humidity extraction knob on Maximum.
2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.
3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.
4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.
5. Ambient air temperature at floor level is between 40 - 65 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air
temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.
If
none of the above solves the problem, it may be a case of the
compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are
5 years old or older. It's rare in a unit younger than that. But, it
can happen.
I hope this helps you to trouble shoot and solve the problem. Thanks for choosing FixYa.
I HAVE THE BHD-301-D COMFORT
The filter is located behind the front louvers. It can be accessed by removing the water collection bucket and looking up into the bucket holder, just behind the louvers. You should see a plastic pull tab handle, which is the filter frame. If you have never removed the filter for cleaning, it may have a piece of plastic tap, which was used for shipping. you will need to remove the tape and discard it, before pulling straight won the filter frame.
The filter can be cleaned by vacuuming it or if it's really dirty, washing it it in warm water and mild dish washing liquid. Rinse thoroughly and shake off any excess water and dry the filter completely before reinstalling it. Never operate the unit with out the air intake filter in place.

I stored two different comfort air dehumid. for
Hi,
Yes... set the dehumidifiers up on blacks so that the hose drains downward and your problem will be solved... make sure the hose is supported so that it steadyly slopes downward and does not trap...
The outlet is very crappy and the hose does not seal well ...also make sure the hose end has a washer in it...

What do the control knob
If you have an analog unit the humidity extraction knob should be turned to Maximum.
If you have an LED screen, the arrow down button is what determines the amount of humidity to be removed and maintained. In this case, the lower the number does mean less humidity.
On an analog unit, it's the higher numbers that determine the lower humidity levels.

Hose attachment to drain water to sump pump not
If you hooked up the hose correctly, you had to remove the drain cap.
If the hose is longer than 5 feet, that's part of the problem. The hose must slope down and straight to a floor drain. It relies on gravity to drain.
Although
you just purchased it, the hose connector and inner tubing may be
clogged. This is another reason water is diverted to the bucket. Turn
the unit OFF & unplug it.
Using an appropriately sized, 18" long, plastic
Zip Tie, carefully insert the tip of Zip Tie into the hose connector and tubing.
Continue to push it in until you reach a bend in the tubing. You will
need to gingerly work the Zip Tie past this bend, until it either
bottoms out or you run out of usable Zip Tie. Then slowly pull the Zip
Tie back out while rotating (twisting) it. This will breakup any clogs.
As you reach the inserted end of the Zip Tie, be prepared, as some water
may follow. Reconnect the hose, plug the unit in and turn the Master
ON/OFF Switch to ON. Set the humidity extraction level to 35% or
Maximum if you have a manually controlled unit. Allow the unit to run,
while you monitor the hose for water flow. It may take 5 to 10 minutes for water to appear.
NOTE: If you don't have a Zip Tie, you may use something similar ( i.e.a long pipe cleaner), but NO wire coat hangers.
Hope this helps you to troubleshoot & solves the problem. Thanks for choosing FixYa.
Although I have attached a
What is going on is that either the hose is to long (should not be more than 48" long) or it's clogged or the hose connection and it's tubing is clogged. When any of the aforementioned occurs, water is diverted to the bucket.
Turn the unit OFF & Unplug it.
Disconnect the hose and check it for a clog and it's length. If none is found, the clog is in the hose connector on the unit or in it's tubing. To clear the clog, do the following:
Using an appropriately sized, 18" long, plastic
Zip Tie, carefully insert the tip of Zip Tie into the connector & tubing.
Continue to push it in until you reach a bend in the tubing. You will
need to gingerly work the Zip Tie past this bend, until it either
bottoms out or you run out of usable Zip Tie. Then slowly pull the Zip
Tie back out while rotating (twisting) it. This will breakup any clogs.
As you reach the inserted end of the Zip Tie, be prepared, as some water
may follow.Reconnect the hose making sure it slopes down and away from the unit, plug the unit in and turn the Master
ON/OFF Switch to ON. Set the humidity extraction level to 35% or
Maximum if you have a manually controlled unit. Allow the unit to run,
while you monitor the hose for water flow. Keep in mind, drainage relies entirely on gravity. The water will not drain up.
NOTE: If you don't have a Zip Tie, you may use something similar ( i.e.a long pipe cleaner), but NO wire coat hangers.
