Goldstar DH304 Dehumidifier - Answered Questions & Fixed issues

You'll have to remove the sensor with wires attached. When sensor is warm you will have continuity (need a circuit tester of some type). Put the sensor in your freezer for about 15 minutes. The relay in the sensor should open and there will be no continuity. If there is continuity after removing from freezer, sensor is defective.

Runs for a few minutes then shuts off, easy fix. First, remove water catcher and slide filter out and clean it. Then find the two screws that hold on the front panel remove front panel. Make sure the unit is un-plugged. The humidity control dial has two wires connected to it. clip the inner wire. This will keep the unit on full. You could replace the humidity control dial, but why bother?

If it is reasonably clean inside and the room temperature is in the 70's you probably have lost some refrigerant gas or the compressor has lost some capacity. Look in side to be sure the coil is not frozen and the compressor is actually operating.Good Luck,Gil

Denis, the problem could be the result of a couple of basic things.

1, The air intake filter needs to be removed and cleaned.

2. The humidity extraction level may be set to high. Lower it to 35%.

On the mechanical side: The fan motor may have failed or the wiring to the fan motor may have come loose. In addition, there is a sensor that controls the fan's operation and that may have gone bad.

With all of the above, I'm betting on one or both of the first 2 things.

Hope this helps you troubleshoot & solve the problem. Thanks for choosing FixYa.

A couple of things can cause your problem.

The water collection bucket is not installed properly or is full. Remove the bucket and empty it if necessary. Then carefully reinstall it, so that it fits "squarely" in to the holder from top to bottom. It must make firm contact with the bucket safety removal switch on the back wall of the holder. Also, while you have the bucket out, check inside the top of the bucket for a float valve (if yours is so equipped), as it may be stuck in the UP position, Jiggle the handle to get to return to the DOWN position.

If all of the above fails to solve the problem, check the outlet the unit is plugged into, to make sure there's still power to it and that the circuit breaker for that outlet hasn't been tripped. If it has, unplug the unit, before resetting the breaker.

I hope the above helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

Before giving up on it. Test the outlet it was plugged into, to see if there is still power there. If not, a circuit breaker may have tripped or a loose wiring inside the outlet.

Hello
Try setting the humidity level lower to force it to run longer.Also check your full bucket shut off switch is not loose or causing it to stop.If there is a filter usually in the back, clean it off with fresh water.
Some dehumidifiers need 5 to 10 min to sence humidity before they continue to run.

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.

Just below Maximum, if it's hot and humid where you are.

If you asking where the humidity extraction knob should be set for optimal humidity extraction. It should be set just below Maximum. Im assuming you have a manually controlled unit, rather than one with an LED screen. If that's not the case lower the numbers using the air down button to 35%.

Hope this helps you and thanks for choosing FixYa.

If your dehumidifier is freezing up then that actually means the unit itself is working well, and you probably just have the machine turned up too high for the current 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.

That's an indication, that the filter needs to be removed and cleaned.
Turn the unit OFF & unplug it before removing the filter. You can vacuum the filter or if it's really dirty, wash it in warm water and dish washing liquid. Rinse thoroughly and allow to completely dry, before reinstalling. Never operate the unit without the filter installed.

If the coils continue to frost, but not defrost, they also should be cleaned.

Fortunately, it doesn't require a special hose, as a standard Garden Hose Connection is on the left side of the water collection bucket. You may have to carefully drill a 1/4 " hole in the center of the connection, once you unscrew the drain cap. The hose should be no longer than 5' , as the drainage relies entirely on gravity to drain.

When attaching the the hose, be sure that the female hose connection has a washer in it or it will leak. Hand tighten the hose connection firmly, being careful not to crack the plastic hose connection on the tank. Also, be sure that the float valve in the tank is in the DOWN. position or the unit will not run.

Hope this helped you. Please let me know.

The problem you're having sound like the drain tubing to the bucket is partially clogged. But, it is resolvable. Here's what you'll need to do.

Turn the unit OFF & unplug it from the wall. Remove the bucket and at the inside top of the bucket holder, you will see a hole or a tube that drains water into the bucket.

Using an 18" long plastic Zip Tie or something similar (NO wire coat hangers, though) that is appropriately sized to fit in the drain hole or tube. Carefully insert the Zip Tie and work it in, until you reach a bend in the tubing. You will need to gingerly work it past this bend, until it either bottoms out or your run out of usable Zip Tie. Then, slowly remove the Zip Tie while rotating (twisting) it. This will dislodge any clogs. Once you start nearing the end of the inserted tip, be prepared for some water to follow.

After completing the above, reinstall the bucket, making sure that it fits "squarely" from top to bottom into the bucket holder. The bottom should not tilt down at all. Plug the unit in, and turn ON the Master ON/OFF Switch. Lower the humidity extraction level to 32 -35%. If you don't have an LED screen on your control panel, set the manual control to Maximum.

One other thing that you want to do on a regular basis. That's remove and clean the air intake filter, if necessary. Be sure to turn the unit OFF and unplug it, before removing the filter.

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