I have a 4-yr old LG dehumidifier 65 pts. This year when I went to use it I noticed the "actual" reading was much too high. I know this because I have another humidimeter on the wall and I know the air was very dry. So it seems the LG is not reading correctly. Since the humidity set point looks at the actual for comparison (two side-by-side digital displays) I fear this unit is cooked. (It does seem to run all the time now.) Am I probably right, or any ideas? Thanks. Frank
Does it use batteries perchance? just a wild guess. maybe a dirty sensor?
I have a Danby that is similar to capacity to yours and it's humidity reading never matches the accurate ones. As long as it pulls water out of the air when I ask it to, that's fine with me.
You won't get things accurate, so keep that in mind.
Does it have a battery? Hmm. Do all the models like this one that restart after power failures have batteries? Never thought of that but will look into it. I will be going away for extended periods so do not want the unit to run all the time if it doesn't have to, which it might if the humidistat doesn't work right. I have noticed differences bewteen the wall unit and the dehumidifier display but this is a mile off.
Went to the LG web site and looked through the manual of the current 65 pint product. It has a 5 yr warranty. Before you give them a call. are you sure that the display is showing the "actual" RH? The manual does not mention this feature. It displays the "set point". I suspect that you need some service. It's not a "humidimeter", it's a hygrometer.
I knew humidimeter was wrong but couldn't think of the other one...:) There are two displays side by side- one shows actual (or what it thinks is actual), the other shows the set point. I think service is in order.
Everyone that I know that has experience with these says the same thing. They only last a few years. I had a Sears, made by LG. The blower fan burned out. Bought a replacement fan from Sears and it lasted one year. Bought another fan and it smoked as soon as it turned on.
Replaced that one with a GE and it lasted two years. I did buy the extended warranty on that one, something I almost never do. But knowing what crap these are I did. So, just got a brand new Amana to replace the GE.
To the OP's question, like someone said, is he sure it even reads the current humidity? Some only display the setpoint. And some display the temp in one display, the setpoint and/or current humidity in the other.
He says it's running, but is it removing any water? The Sears/LG I had, the blower failed, but with the compressor running it sounded normal. Is good air flow coming out?
Finally, there is the mystery of my new Amana. When set to 55 it maintains about 52 as indicated by both it's own display and other units. But when I set it to
60, it then maintains 63. Which makes no sense at all. All in all, these things sure aren't what they used to be.....
I shut the unit down for about an hour to replace the drain hose connection. When I restarted, all was fine! I guess there was some icing. Never encountered that before in all the years I have been using this dh (since 2008) but the cellar was quite cold when it was first turned on (which it always is.) Also I have a transparent drain hose and the dh seemed to be functioning just fine through all this despite the icing. Also a mystery as to why the icing would have caused "actual' humidity to read incorrectly high. More penance I suppose...should have noticed the icing right away! (Thanks all for your help!) Frank
...unless the ice acted as a moisture source. With no melting tho I'd wonder. Does stable ice (not melting) create moist air around it? Anybody out there good at this?
Some dehum have a "freeze stat" that turns off the compressor when the coils start to freeze.
A good refrigeration guy can add freon. Or a freeze stat, or both.

Time for a new dehumdifier. Icing usually indicates low freon (or its not a low temp dehumdifier) and its usually a sealed unit. At least mine was, and it lasted about as long as yours before I had to buy a new one. The new one works great, the old one ices up when running side by side.
