Maytag m7dh65b2a freezes up ,

This is a common problem with most dehumidifiers, not matter who the manufacturer is. The best way to prevent it is routine maintenance. Especially when you stop using it for the season. Dismantle it and clean the unit thoroughly. Putting a light coat of WD40 on the coils and contacts will help abate corrosion during the off season. If you are in an area where you use the dehumidifier continuously , then you should step up your routine maintenance to every 6 months. Cleaning the filter regularly, will help expand the dehumidifiers life span. By the way, the model you listed was manufactured by Fedders for Maytag.

Keep up the routine maintenance.

Hi,

Here is a tip that I wrote that will help you understand why and what you cando with a dehumidifier that ices up.

Dehumidifier is Freezing up and not working

probally has lost some charge on the refrigerant. Low charge will ice the coil. Unless you are operating this at low temperatures. The ones I have seen do not have a defrost on them

Unless you have special model, that's what happens at 60 or less. defrost over a drain (it won't run into the bucket) and move to wamer location or face a electric space heater 2-3 feet from it

is the filter dirty or is the air flow not as much as it used to be - low freon pressure - low air flow causes a/c units - dehumidifiers to ice up - if fan is running normal are the fan blades dirty

Condenser coils do not freeze, it is the evaporator coils that freeze. If it is icing up then the setting is too low for the area it is in, basically the humidistat will never be satisfied so it will run continually and end up freezing the evap coils, the coils could also freeze if the filter is dirty or there is an air flow problem.

There was a clip (rusted off) that held mine to the evaporator coil. I used a wire tie to hold it between 2 evaporator coils.

Its too old where you are running the appliance - lift it up in the air or raise the heat in the room. This is *not* a low-temp dehumidifier.
