I've had this Maytag dehumidifier for about 2 years now, and in the last couple of months, the coils have began to frost up every time the unit runs. No water accumulates in the bucket. It started when I unknowingly let the unit run for about a week while it was frosted up. I've taken the unit apart and cleaned the coils, and the problem continues. It is not very cold in my basement. Is my dehumidifier shot, or is there a fix to this? Your comments would e greatly appreciated.
I have the same problem under 5 year warranty. The Authorized May Tag Dealer (Stan & Pauls), advised that they were unable to duplicate the condition. I then took it home, let it run for several hours and brought it to them with the Evaperator completely frozen in ice. They then ran it in their shop and stated that it will not freeze their. It is interesting to note that this model is supposed to detect, icing and shut the compressor off and turn the fan on high for a while. Evidently this feature does not work on mine and can not be repaired. No more Maytags for me.
It needs gas. Quite simply the only way it can freeze up is when the refrigerant gas is getting low to the point when it starts super-expanding at the evaporator. Any authorised refrigeration technician should be able to top it up, and check it for leaks - there may be a seal that is partially shot, or possibly a leaky joint / pipe / compressor. A refrigerant leak detector will track this down quickly. Only thing is - get a quote for the work first - sometimes refrigerant is pricey enough to make it close to not worth it on some units. Unfortunately this is not something you are permitted to do yourself (topping the gas up, not the leak checking) due to environmental legislation. Good luck, it should be worth doing, otherwise it will probably continue to get worse until the compressor fails, maybe quite quickly. Hope this helps :)
I am on the third year of a 5 year warranty with same symptoms. I took it to one approved factory repair center in Dover, NH, and they were unable to duplicate the problem. I have limped along all summer. It runs sometimes for a week or more and some times for only a day. I have to shut it off for more than 24 hours for it to run properly again. At the factory's suggestion I took it to another authorized factory repair center in Goffstown NH where I was told the Fedders was no longer honoring the 5 year warranty as of September 9, 2007 ??? They have had a number of these units in for repair with the same symptoms. I was told that if I wanted to pay for repairs it would cost $80 - $100. When I tried to call the number used last Spring it was no longer in service. Their web page no longer lists dehumidifiers. The Maytag myth appears to have evaporated with the acquisition by Fedders.
Mine is 2 years old with the same problem. I can see through the side slot and front grill that a thermal sensor that should be reading the coil tempurature is loose. It's loose because the metal clamp holding it on has rusted through and fell off. If this model was built with a rust prone clamp attached to the end of the coils that are wet all the time, then this is probably happening to a great number of these models after 2 years depending on use. To fix it I need a clamp and how to open the outer case to get to the side of the front coil. Any ideas?
