Frigidaire FAD704DUD 70 Pt. Dehumidifier



Don't last, warranty practically useless
I bought mine at the local big-box home improvement store. It is used in my heated basement, which I want extra-dry as my firearms and other sensitive items are stored there.

After six months it started making a lot of noise. I checked it and found that the cooling coils were completely iced up, totally blocking the air flow. I let it defrost completely and tried again, with the same icing resulting after a few hours. I checked the manual. which gave "room temperature is too low" as the cause. Doubtful, I thought, but it is winter and only about 60 degrees in here. So I waited to spring and tried again. Now there is no cooling effect at all, and no water output. Obviously the icing was from the cooling fluid leaking, and finally it all leaked out resulting in the total lack of operation.

This is my second Frigidaire dehumidifier. The first had a fan motor failure after six months.

Obviously Frigidaire is no longer synonymous with quality.

Works like a sponge--but needs a modification for hose drainage
This unit sucks water from the air by the gallons. I set it up in my finished basement and right out of the box it worked great. So well, in fact, I needed to empty the large capacity tank too often. So I opened up the back hose valve, connected a short garden hose and pointed it to the floor drain. The unit kept filling up the tank and did not drain out the hose :-(. It appears that the hose drain in the back just works on gravity--there's no pump. So if the floor is not level and/or if the hose is a little narrower than the male connector on the back of the unit (as most are) the water will not drain through the hose the valve. The fault is poor product design. To remedy, I bought a right-angle PVC adapter, barb adapter and clear tubing (to visually see whether it was working) from Flex PVC.com. Parts: "508-007 FGH by .75 FPT (female NPT) 90degree", "PPN46 3/4 mpt x 1/2 barb adapter", and "1/2 x 5/8 Clear Tubing BTF". The right angle adapter is large and maintains the 3/4"...

Newer Version - Works Great ... So Far
I owned the previous version of this dehumidifier (Frigidaire Dehumidifier, 70-Pint Capacity, FAD704TDP) and the compressor failed in just over 1.5 years. I was disappointed by this, but it was not unexpected. My previous research of customer comments on both amazon.com and Consumer Reports indicated that failure in 1.5 years is now the norm for dehumidifiers! (I wonder whether the new government regulations have anything to do with this - FYI, they now prohibit the use of FREON and the failures in a couple of years started after that; previously dehumidifiers lasted 10 or more years). Note that everyone who wrote reviews in 6 month or less after purchase was very pleased with the dehumidifiers in general (as was I), but reviews written 6 or 12 months after purchase started to complain about failures (compressor mostly). Very disppointing since all my previous dehumidifiers lasted well over 10 years; and one of them is still working fine. But I needed a dehumidifiier and this...
