Frigidaire FAD504TDD 50 Pint Dehumidifier Review

Frigidaire FAD504TDD 50 Pint DehumidifierAtt. The highly appraised Frigidaire FAD504TDD Dehumidifier is no longer available after being slowly phased out of the market since May 2012. It has been substituted by the NEW Frigidaire FAD504DUD unit which is the current 50 pint dehumidifier model that replaces the FAD504TDD in the Frigidaire range.

Must Read : How Much is a Pint

The new FAD504DUD maintains all the great features of the FAD504TDD model, while adding some improvements that include: A more compact design (weighs 1 pound more and is a slightly larger), has a different looking but very user-friendly Electronic Controls Panel and is a little quieter, at least according to the many Customer Reviews.

When the FAD504DUD was introduced in May 2011, it had problems with a faulty continuous drainage system. Frigidaire was able to fix this problem with a new drainage kit and now the new model is one of the top selling Dehumidifiers in Amazon.

Apart from the improvements mentioned above, everything else is identical, so the Dehumidifier review (below) of the “phased out” Frigidaire FAD504TDD still applies to the new model, Frigidaire FAD504DUD 50 Pint Dehumidifier, which has been in the market since the Spring of 2011.

Read the full Dehumidifier Review of the OLDER Frigidaire FAD504TDD Dehumidifier Model below:

The Frigidaire FAD504TDD Dehumidifier is an Energy Star rated unit that could filter out up to 50 pints of water per day from your home. This Frigidaire unit comes with an Effortless Full Tank Alert System that will automatically shut off the unit when the bucket is full, letting you know that it’s time to empty it. The splash guard and carry handle make emptying the water really easy. As an alternative you can attach a hose to the FAD504TDD and allow a continuous discharge of water to a nearby drain, avoiding the need to unload the water container manually.

The Frigidaire FAD504TDD Dehumidifier weighs 39 pounds and is fitted with four caster wheels as well as three carrying handles; one on top and the other two at the sides to make it easy to move the unit around the different rooms or basement in the house. The Frigidaire FAD504TDD has a full-function electronic control panel, featuring an easily accessible collection container with level indicator as well as a washable clean filter that removes moisture, harmful bacteria and allergens, helping to keep the air in your home smelling fresh and clean.

The Frigidaire FAD504TDD 50 pint Dehumidifier has an adjustable humidistat that helps you control the amount of air that the unit sucks in to be dehumidified, allowing it to increase or decrease the level of humidity in the range 35% to 85%. The most comfortable level for most people is about 50%, give or take 5%.

This feature is important as it helps to save energy by switching the dehumidifier’s compressor off once the desired relative humidity is reached. But even though the compressor switches off, the fan will continue running in order to provide a flow of air for the humidistat so that it can sense the humidity in the room and will “know” when to re-start the compressor.

Another important feature on the Frigidaire FAD504TDD is auto-defrost. This will stop the refrigeration process by stopping the compressor. The main purpose of auto-defrost is to protect the dehumidifier from damage. A sensor detects the formation of ice on the cold coil and turns off the compressor. The fan keeps running and the flow of ambient air melts the ice. This is normal in dehumidifiers with this feature and is regarded as a safety feature that should also prolong the life of the FAD504TDD.
