Question about LG LHD45EL Dehumidifier

1 Answer

The compressor does not kick on - this is the second one I have purchased in the last couple of years and believe there must be some things I can check out on my own. I only run it during the summer months in the south.

Yes, there are some things you can check.

The first thing to check is the setting on the Dehumidifier. If it's above 60%, it's not likely that the compressor will turn ON, as 60% is a pretty high humidity level. Keep in mind, if it's set at 60% that's what it will maintain, not remove. Lowering the level to 45% will have a much bigger effect.

Now, let's suppose, after turning the setting down, it doesn't cause the compressor to turn ON.
Take the unit into the bathroom, plug it in and turn it ON, with the Humidity setting at 45% or lower. Turn the shower on, using hot water and on the way out close the door. DO NOT run the exhaust fan in the bathroom. Wait about 15 to 20 minutes, return to the bathroom, turn the shower OFF and check the water collection bucket for water. If any water is in the bucket, your unit is working as it should.

Routine Maintenance:
Check and clean the air intake filter regularly. A clogged filter causes the compressor strain to keep up. Also, cleaning the coolant coils prior to using it in the Summer, can go a long way. After cleaning, a light coat of WD40 really helps.

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

How do I determine reason that my Danby Dehumidifier isn't cycling on to compressor for more than 3-4 seconds at a time? Fan always runs but compressor only kicks in for 3-4 seconds then back off.


I would say low on gas or bad switch/thermostat.
The compressor probably has a shutoff for low freon. You would need a set of gauges to check for that.
Bad thermostat? You'd need a ohm meter.
User error? What kinda settings or controls do you have on the control panel?
There was a recall on these in 2014 for catching on fire.

It is probably the start device(the coil looking things), as long as you don't hear the compressor humming. A loud hum is a lock compressor and the cost would be far greater than a new 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.

Will run but won't take moisture out of the air


Fedders, the maker of the maytag dehumidifier, went bankrupt and they are not honoring the warranties. call this number and if it is still under warranty, they will send you a prorated check for the remainder of your warranty. 1-866-629-8241. we had two months to go on our warranty and they gave us $14 and change.
