Question about Goldstar DH304 Dehumidifier

1 Answer

Goldstar DH304 Freezing up / no water in bucket

Room Temp 70F or 21C
Fan and Compressor motors both work.
Coils are clean and air movement is good.
Took off front cover and frost is present on the lower coils. Unit does turn itself off and on .... assuming this is the defrost mechanism.

No water in bucket even though the carpet in my office is wet due to spring seepage.

Anyone have an idea what would cause this ... doubt it is lack of refrigerant as the lower coils get cold enough to frost over within seconds after the compressor kicks in.

Thermostat or the temperature control module are not working properly. Also make sure that your fan blades are not broken or warped as this will cause you a problem. Also if the coils have or do get iced up then it will be a low coolant problem. But this is a thermostat or temp control problem

Fan works. Filters and clean. Heater a Can aster seems warm. Room is damp. Unit does not produce water


There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2.. Yiu have already cleaned the filter, so that one's covered.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a mechanical unit
turn the control knob to Mai=ximum.

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 - 60 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.

Hope his helps you to further troubleshoot and solve the problem. Thanks for choosing FixYa.

My Goldstar GHD30 dehumidifier is not putting out water


If the machine's compressor runs when you switch it on, then turn the machine on maximum and let it run for an hour or so. Then check the coils in the back with your hand. If they are not getting cold at all, then there is a significant problem with the refrigeration process in the unit. It may have developed a leak and allowed your refrigerant gas to escape, or there may be another internal problem with the compressor. Either way you would need to have it serviced by a fridge technician, or more likely just replaced with a whole new unit since both options can potentially cost about the same.

If the unit runs normally and the coils are getting cold, then make sure they are not totally icing up which will impede the unit's performance. If your dehumidifier is freezing up then that probably means the unit itself is actually working well, and you probably have the unit turned up too high for the conditions.

Try turning down the setting on the unit so that it cycles on and off every few hours and does not run continuously.

Also try using some warm soapy water to clean off any dust or oily residue from the cooling coils in the rear of the unit. Remember to also clean the air intake filter while you are at it.

The ambient temperature in the room may also be a bit too low, so you can try adding some heat to the room if necessary. A dehumidifier will not work properly if the ambient air temperature is too low. Basically, the warmer and more humid the room is, the better they work. Since warm air rises, you can even try lifting the unit higher up off the cold floor onto a bench or table where the air is warmer.

Sometimes the drain tube leading to the bucket is clogged. You can often clean this out by inserting the pointy end of a long heavy duty plastic zip tie and jiggling it around a bit. Do not insert anything metal or sharp into the tube or you may damage it.

My Goldstar dehumidifier model DH304 runs,but fails to pick up any water


If the room air is less than the set air, then there is no water in the bucket, because there is almost no humidity in the air. If it is winter, there is likely not enough humidity in the air to have water collect in the bucket. A dehumidifier will only pick up humidity out of warm air. If you are running a dehumidifier in your basement in the winter, the room may be damp, but too cold for the dehumidifier to pull out the humidity. Try running the unit in the bathroom after having a hot shower without the bathroom fan on. If working correctly the unit should draw water.

Other things that can cause problems: 1.Check to see if the air filter is dirty and/or blocked. 2. The room temperature might be too low, (below 60 degrees Fahrenheit ) 3. Check to make sure that there is no obstruction to the unit that might be causing poor airflow circulation.

Hope this helps you to troubleshoot & solve the problem.

Hi

You need to check that the bucket is clean and that the sensor for the water level in the bucket is clean.

An old toothbrush and some warm soapy water can sometimes achieve a great result.

Failing this you may need a new sensor, be careful and either draw or photo the old wiring route with your cell phone to make it easier to fit the new sensor

Hope this helps

I don't have the manual and need to replace and/or clean the air filter on my Goldstar DH304. Where do I find it on the appliance?


if this is the correct picture - pull out the collection bucket and reach just inside the opening at the top (just at the bottom of the grill in the front) the filter is plastic and pulls straight down. Clean it tin soapy water, dry it, and slide it back it place.

Is Part # 3850A20500F one of this model? my unit


I found the model # on my Goldstar DH304 at the top of a sticker on the inside of the unit behind the bucket. Mine has stopped working too. I'm awaiting an answer to my problem but after some research it seems that unless the filter and/or coils simply need cleaned, there is lttle that can be economically repaired. Good luck.
