I would say yes, the fan has to run when the A/C is on, if not it will freeze up. I have no clue if you have a variable speed fan.

Our dehumidifier is running some of the time an not at other times but no longer has any water in it (for several weeks) Is something busted?


to test your unit simply lower the humidity setting an see if it comes on in a few minutes , if it does listen for two motors to run (compressor and fan) this is normal , if not then it might have a problem then

reset humidity setting to normal (72%rh)

When turn off. makes a humming sound. compressor seems to be running.


Have same issue with 3 year old Frigidaire dehumidifier purchased in 2012. Must unplug to stop compressor running with power switch turned off. Unit gets hot and smells. Unplugging creates arcs at outlet since unit is pulling a lot of power. Plugging back in after some hours will make it appear to run normally and again remove moisture but it will not shut off when the fan goes off (humidistat bad?) and the set-point is reached. Cannot leave plugged in due to safetty/fire/overheating concern. Have not found answer on this forum or any other so far.

Compressor runs and gets hot but fan will not kick on. Replaced the capacitor and that did not help. One side of coils gets hot, the other side gets cold, which seems normal. Just can't get the fan...


Don't run the compressor for any length of time without the fan operating. Is it possible that the fan must be replaced? Can you power the fan safely to test it?

When the humidity set point is reached, the compressor shuts off but the fan continues to run. Is this normal?


Chucke - Depending on which mode you're operating the unit in (Continual Mode), yes that is normal.The fan continues to run in an effort to recirculate the air. If it senses a rise in humidity above the level you have it set on, the compressor will turn and remove that humidity.

Hope this helped you.

Not creating water. Unit runs but the cistern does not fill up like normal


Many times on a dehumidifier we hear the fan run...and think all is ok. But the key is if the compressor is running. Listen for the "refrigerator" type sound ....It must first be determined if the compressor is running...and if so is the filter and the coil behind the filter clean

Unit runs but no water collects in bucket. Unit is over a year old and has run continuously that whole time. Up till now it has performed beautifully. Is it just worn out?


Hi;
Your dehumidifier is similar to a refridgerator or air conditioner. It has a compressor and coils, and a fan. Basically, the unit has to **** in air with it's fan, and as the humid air goes across the cold coils, the humidity condenses in to water. If the coils are not getting cold, they won't condense any water, or if the fan isn't running, or the coils are dirty. If you check your unit over, see if you can tell if anything isn't working. Make sure the control knob is set at the highest setting. If the compressor lost it;s refridgerant charge, and won't get cold, it isn't probably worth fixing

DH30 Dehumidifier Compressor Does not Operate


I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad.
Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.
