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

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.

Tip

Dehumidifier VS. Air conditioner


A dehumidifier is basically the same thing as an air conditioner but both coils (condenser and evaporator) are in the same unit meaning a dehumidifier exhaust warm air in the same room it is in. running a dehumidifier would make an air conditioner run more because of the warm exhaust, when you run an air conditioner it acts like a dehumidifier and dries the air. As far as saving energy it all depends on the size of the AC and dehumidifier and the size of the room. If you want warm dry air, use a dehumidifier; if you want cool dry air run the AC but not both.
How do all these parts fit together to pull moisture from the air? It's fairly simple, but very effective:
  1. A fan collects air from the surrounding area and pulls it into the dehumidifier.
  2. As the air passes through, it comes into contact with the dehumidifier's cooled coils. These coils use condensation to pull moisture from the air. The collected moisture remains on the coils and drips into the dehumidifier's reservoir.
  3. The dehumidifier reheats the air and exhausts it back into the room.
A dehumidifier usually has a removable plastic bucket for are reservoir; most buckets also have a place where you can hook up a hose so the collected water can drain straight into a floor drain or pump. This frees you from having to remember to dump out the water. But don't worry too much about the reservoir overflowing -- most dehumidifiers also have an automatic shut-off. If you're using a dehumidifier in extremely moist conditions,however, or if you need to keep your dehumidifier on all the time, you should look into a unit with a built-in condensate pump, which regularly pumps water out of the unit's reservoir rather than simply relying on gravity to empty it as a hose does.

Just bought, brand new. where to put water in? unit will not turn on.


If you bought a dehumidifier, you will not need to put water in it. A dehumidifier removes water. A humidifier add moisture to the air, and you need to add water to this. Was your dehumidifier running before and then it stopped? If so, it will have a tank on the bottom that will have water in it that needs to be emptied out. Let me know if this is your problem.

HOW TO USE


Hello,

follow the instructions below on how to use your dehumidifier:

Prepare the room for the dehumidifier by vacuuming, dusting and cleaning the room. Be especially careful to have all mold removed prior to using the dehumidifier.
Plug in the dehumidifier into a grounded outlet.
Set the dehumidifier to high in order to remove excess moisture from the room.
Wait for the dehumidifier to run several cycles, removing all undesired moisture from the air. This may take days or even weeks in especially damp rooms.
Adjust the setting of the dehumidifier when the air has reached your desired comfort level. Make the setting one that will maintain the current conditions.
Good luck.

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.

Everything seems to run fine, just hasn't pulled a drop of water


remove the back airfilter, and touch the tubes while the unit is running, if nice and cold, all is well, there just isnt any moisture there. but if compressor is running and tubes are warm , means freon/coolant has leaked out

Unit will run but will not kick in to remove moisture


the compressor sounds like is not coming on check the refrigerant or check the power to the compressor it could be something as small as a humidistat which will not tell it that we still have humidity like a thermostat
