Question about DeLonghi Dehumidifiers

Have a DeLonghi DE40P dehumidifier that ran great for 10 years and just stopped pulling moisture out of the air. Want to know if system just lost refrigerant charge or defrost control board failed?

- When unit get's switched on, fan comes on and dehumidifier cycle light goes on, but no compressor. - after about 3 minutes, dehumidifier light goes off but compressor switches ON. - Only the capilary tube between condenser and evaporator frosts up. When the compressor cycles off, the capilary tube frost melts, giving a few drops of condensation but not enough to reach/fill the tank. - System apprears mechanically sound with some rust on evaporator coil end loops. -I'm better mechanically than with electronics but seems to be a board issue - any debugging thoughts to help isolate the problem?

Pull the bucket out... reach up under the bottom edge of the display bezel and pull down on the back edge to get the filter out; rinse out/off thoroughly, dry and reinstall it...

Get some airflow thru there!

Good Luck!

What do you have the humidity level set at on your dehumidifier? The average is 65%. Make sure you do not have it set at 75% because if you do this could be causing it to keep the humidity so high.

Your unit has a sealed system leak. The sealed system is warrantied for five years. Check your owners manual for this info. You will need your receipt and to call an authorized LG warranty dealer to exchange it.

I need the intruction manual for Delonghi dehumidifier model #DE40P.

Here is a link to the Owner's Manual, you're looking for. You can download and print the manual for future reference. Take good care of your model, perform routine maintenance, as required. As it no longer in manufacture. It has been replaced with a 45 pint unit. However, some parts your model are still available, if needed.

Hope this helped you.

The unit just stopped extracting any moisture from the air. The fan runs and the compressor sounds like it turns on. I use the bucket to capture the moisture so do not have the pump on for the hose.

If the unit isnt extracting moisture in the air you have one of two problems a leak in the refrigeration system or the compressor is locked up. In my experience its probably a leak in the refrigeration system because they make the dehumidifiers very cheap and the coils are paper thin. Delonghi has a lot of issues with there dehumidifiers and any other appliance they make. Check to see if the compressor is running if it is then you have no freon in the system. You can access the compressor by the back panel and you will know if it is running. If it is a refrigeration leak buy a new unit it will be a whole lot cheaper and less stressful,.
If this helps please rate me.

Icing up on our dehumidifier

typically happens when there is a lot of dust in air. Try cleaning it VERY well, which would mean, shutting it for a few days, letting it melt and dry off, then not only vacuuming it, but then take an air gun (or Air in a can) and get the dust off the coils. Obviously if there is a filter clean it, or replace it.
Check for bent fins on the coil. Most of the newer ones (and yours should as well) have an auto defrost to help with that.
Good luck
