Question about Aprilaire 1700 Dehumidifier

Open Question

I have a aprilaire 1700 dehumidifier. when i turn up the control, the fan starts then a minute later the compressor starts. the cmpressor runs for about 20-30 seconds, then shuts down and so does the fan. i know that both the fan and compressor are operating fine. wondering if the issue is the control or power center? i am a hvac service tech, but do not have much experience with these units. thank you.

Hi,
Have they messed with the wires to the humidistat??
Either they are unhooked or they shorted out the wires and burnt out the transformer...

SOURCE: what does a blinking green status light mean on

http://dl.owneriq.net/a/a64a1426-8226-4b14-9621-800688d1ff17.pdf
her is a manual and will cover the usage and settings ..but for flashing green lights ...it indicates a malfunction ...and it can only be something related with the drain ..water tank or the fildter needed to be cleaned or changed..
Check the water tank to be on level .and also see if it has a floater inside, that can be stuck .if it has one ..this is for to sense the presence or absence of the water..(shake it good if you think it is stuck ..
Another operation is to clean the filter ..The filter should be cleaned or changed (if damaged ) once a year ..but in some conditions ..it needs to be cleaned more often ..The cleaning is made under he tap with warm (not hot ) water..
The drain trap or outlet should be checked and cleaned of debris annually. Flush it with water
under pressure to ensure opening is clear.
if all that is done and still blinking ..than there is something physically wrong on the fan area ..and this should be checked by a repair-man

Why does compressor continue running, even with dehumidifier turned off?


Hello Bernard, thank you for your post!
I see that you are experiencing an issue with the Frigidaire dehumidifier, FAD704DWD, compressor consistently being on. This could be a possible issue with your control panel or sensor. Since it could be any one of these underlying issues I would suggest contacting the manufacturer for further assistance. Hopefully this information is helpful to you. -Matt

I have an Aprilaire 1750 installed inline with my upstairs central air system in the attic. The unit's ducting appears to be installed as indicated in the installation manual, but when the unit is running...


Your dehumidifier is likely working correctly. When operating and removing moisture, a dehumidifier will supply warm/hot air to your house. Your dehumidifier moves less air than your A/C, so your supply ductwork in your house is oversized for the dehumidifier. This will lead to uneven feeding of your supply duct branches with just the dehumidifier operating.

Since your dehumidifier is installed in the attic, make sure that the ducting connected to it is well insulated. Also make sure that your dehumidifier cabinet is insulated. These actions will help prevent heat gain from the hot air in your attic.

Is your dehumidifier bringing in fresh air from outside? If the outside air is hot and humid, the dehumidifier will supply warmer air to your home.

Some people run their A/C fans continuously to help with the air distribution, but this is a bad idea since it increases energy usage considerably.

Fan kicks on but compressor does'nt start. Humidity control checked out. Compressor ohmed out. Fan runs for about a minute then it shuts down.


i would do a continutity check on you relay and overload, other than that
what is the humidity level in the room, as well as the ambiant temp. these mahines cycle for that very reason, the fan will come on, do a check and then determine if it should start the compressor.
check if you have voltage at the compressor when its supposed to be running ( just a last thought)
ive seen compressors ohm out, but in fact be bad

Dehumidifier not collecting moisture


Normal 0 When you push the power button, the blower fan comes on. In a few minutes you should hear a second "click"--that is your compressor starting. Do you hear that second click?

What you think it means is exactly what it does mean. When a running unit is shut off it should not be restarted until the system pressures have had time to balance out so the compressor can restart without difficulty.

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.
