This is a 7 year old unit that worked fine until this year. Fan runs, compressor starts, room temp is good, and all settings are as they normally are (a reasonable difference between room RH and set RH). I haven't taken it apart to try to feel if the coils are getting cold, but my suspicion is a refrigerant leak. Two questions: - is there a way to identify if that's the problem, without dismantling the unit? - if it is a refrigerant problem, is it ever economical to fix? Thanks SN
SOURCE: No drying!
I just got the same model via mail order, and it isn't drying either. I'm going to give it another day before I send it back and buy some other junk product locally that is easier to return.

Hi,
Is there any sign of ice or condensation on the cold pipes? You may be able to see them by removing the filter screen (if present on your model) from behind the inlet grille. There's also a chance that the humidity sensor is clogged with fluff, so fooling the system into thinking the room is pretty dry. A running compressor can usually be detected as a deep throbbing from the machine.
If it is running, but not cooling the pipes, then you may have lost the refrigerant from the system via a leak. If the air coming out of the machine is warm (caused by the compressor running) but there is no water produced this is usually the cause. This is usually beyond the scope of a DIY repair.
Hope this helps. If these suggestions do help you solve the problem, please give my reply a rating to help others judge my knowledge / guessing skills.
If they do not, please hold off on the rating and add a comment with more details so I can try to help you further. Cheers, D

Most dehumidifiers these days have a built in defrost control, which turns the compressor off when the coils frost up while the fan continues to blow to help melt the frost off, so if it is frosting you may need a new defrost control, but first check the following: If your model has an air filter, clean it, as restriction of air flow will contribute to icing. Try to move the unit to a warmer location. Usually the best way to do this is to get it above the floor as far as possible, as the air temp is warmer closer to the ceiling than it is at the floor. Make sure there is plenty of room for air to circulate. (don't push it against a wall)

This dehumidifier is built in such a way that the fan runs all the time;however the compressor works only when it is needed. These infos are not specified in the booklet. It does not work like the old ones.

Make sure you have enough air moving over the coils. There is an air filter on some models which may be obstructed. Insufficient air flow will cause your problem.
