DDR2504 dehumidifier has always worked well. Now the fan runs and all seems normal, but the humidity is not dropping and you can tell that the dehumidifier is not cutting in and out. I do not have it on contiuous fan. Is it fixable?

Derkfarm - It may simply be a case of the humidity extraction level being set to high and/or the air intake filter needs to be removed and cleaned.

Solution: Lower the humidity extraction level to 32 - 35% and clean the air filter.

If the unit is in a basement, the ambient air temperature at floor level is colder than at chest level. Dehumidifiers don't work well at temperatures between 40 - 60 degrees F.

Solution: Set the unit up off the floor on a sturdy table, cabinet, counter top, etc. It must be sturdy enough to handle the weight of the unit, plus a full tank of water and the vibration, while in operation.

Any or all the simple solutions above may solve the problem. But, we won't know, until you try them.

Please let me know if it helped or didn't solve the problem. Thanks.
