Question about LG Goldstar LD65EL Dehumidifier

1 Answer

The condensing unit does not run consistently, it clicks on every minute or so.

I just purchased a large 150 year old home in Mass. The basement is field stone and very unfinished. When I bought it there was standing water at all times. I have since installed a sump pump and french drains (outside) on the wet side wall. I still have 90% to 95% humidity. I purchased the LG last week, but I do not think it is functioning correctly. All dehumidifiers I have used in the past the condensing unit would run for a long period of time. This one runs for seconds at a time. The humidity is down to 80% but will not go any lower. Is this LG damaged?

It sounds like there is an issue with either the controller board or humidity sensor. LG has a 5 year warranty on these models. You may want to contact them first instead of opening it up because it could void the warranty. My recommendation is to have this serviced if it is under warranty. They usually will tell you of a service center nearby which will service it free of charge since it is under warranty. If you do not live near a service center they may ship you a replacement and you send your old dehumidifier back to them. Make sure you have your reciept when you contact them so they can verify it is under 5 years old.

From a cold start, the dehumidifier starts and the fan kicks on. But after running for 2-3 minutes it shuts off. If you remove bucket and reinstall the fan will come on for a short period and shut off...

Wayne, There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have an analog unit
(no LED screen) 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 - 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 this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

Gayle, your unit has some age on it, but it may still be salvageable .

There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. Or set to Maximum if yours
is a manually controlled unit.

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.

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. As far as repairs are concerned: The unit is 14 - 16 years old and the cost to repair, may be as much (or close to it) as purchasing a new unit. If you decide to purchase a new unit, be sure it's a "Low Temperature" model, as yours is being used primarily in a basement application.


I hope I have helped you and thanks for choosing FixYa.

The unit runs but no longer removes water from the air, there is high humidity in the basement. Is it worth repairing the unit because it's 7 years old and where can I purchase another Mayta unit?

I have a dehumidifier that runs but does not pull moisture from the air in the basement. the application is about 3-5 years old. It is a Maytag and I purchased it at Home Depot. The Model is M3DG30B2A A....

There are a couple of things you can check for and they are; First of all, when you say the unit is running you may only be hearing the fan run. The compressor may possibly be not running(if it isn't running you will have no dehumidification as a dehumidifier is really nothing more than a small airconditioner.(cooling a coil for the moisture in the space to condense to). Second, The space may be to cool for the unit to run and dehumidify well, The space should at least be 65 degrees or warmer. Third, the system may have a leak and it is out of or low on refrigerant(freon). Depending on what you paid for the unit and if it has any remaining warranty(parts only-labor not covered) if the system is out of refrigerant or if the compressor is bad it probably isn't worth the cost to repair.

Unit runs a lot. Doesn't condense much water. Sometimes fan runs alone, sometimes compressor runs alone.

You may also want to check the coils and make sure they do not have dirt or dust on them. If they are clean you may have an issue with the refrigerant level which will cause the coils not to cool properly. For that you will want to contact LG. There could be an issue with the compressor also. LG backs alot of their models with a 5 year warranty. Contact them and let them know about your issue. Make sure you still have your reciept. Here is their contact number:

Iced up coils and will not dehumidify

I did a little digging around on the internet and found out that if the basement (or where ever you have your unit) is in an area where the room temp might dip below 65 degrees the coils may start to become "too efficient" in pulling the moisture/humidity out of the air and it begins to freeze on the coils before it can drip off into the reservoir. The site said to turn off the unit and let it thaw out, then restart it and see if everything works ok after that. If the temperature gets too low you might need to warm up the air in the room/basement before it will operate correctly again/not continue to freeze up. Hope this helps. Mine just did the same thing but we've had some pretty cold weather recently and the basement is fairly cold as well.

Goldstar dehumidifier won't stay on

Check the relative humidity in the room or space where you are operating the dehumidifier. Damp feeling and actual humidity level are two separated items. Humidifiers will run for a few minutes until it is signaled that the humidity is already low enough and then shut down.
